Combustion of 0.157g of the co. 1)A compound contains only carbon, hydrogen, nitrogen, and oxygen. Combustion of 0.157g of the compound produced 0.213g CO 2 and 0.0310g H 2 O. In another experiment, it is found that 0.103g of the compound produces 0.0230g NH 3 . What is the empirical formula of the compound? Hint: Combustion involves reacting with excess O 2 . Assume that all the carbon end up in CO 2 and all the hydrogen end up in H 2 O. Also assume that all the nitrogen ends up in NH 3 in the second experiment. A binary compound between and unknown element E and hydrogen contains 91.27% E and 8.73% H by mass.

If the formula of the compound is E 3 H 8 , calculate the atomic mass of E. US Search Mobile Web. Welcome to the Yahoo Search forum! We’d love to hear your ideas on how to improve Yahoo Search .

Nitrogen Analysis & Techniques Used: The method in use is an upgraded form of that originally researched in Switzerland and marketed by various firms in the US. Fundamentally, the scheme involves combustion of a sample in ultra-pure oxygen at 990 deg C in a closed system. The products (gasses) are swept through copper to remove excess Oxygen and silver salts to remove halogens, phosphorus, and sulfur. Since the heat conductivity depends upon it’s composition, the mixture of remaining gasses is sensed. The H2O is removed. Later the CO2 is removed and finally only N2 remains. Sensing is done after each removal. The instrument is calibrated using various standards from the NIST. Thus all three elements can be determined in one run from the same sample selection. Running one sample at a time enables us to check for inorganic residue post combustion. Interferences are very few. Very high fluorine levels (>60%) can cause high nitrogen results.

This can be circumvented. The optimal sample size depends upon theory. It is always best that the analyst knows all elements present (the molecular formula). If completely unknown, the operator will select about 2 mg for analysis. This equipment does well in the analysis of air-sensitive samples. These samples are sealed under nitrogen (in a controlled atmosphere) in preweighed capsules. After removal from the glove box, the capsule is reweighed and quickly inserted into the analyzer. This “special handling” process can be done in less than 4 minutes thus minimizing any degradation of the sample. There is a correction made for the increased nitrogen blank from the glove box gas. Atomic weight 14.00, Atomic Number 7, Melting Point -210 C, Boiling Point -195.79 C. Nitrogen is a chemical element which has the symbol N and atomic number 7 in the periodic table. Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78.08% percent of Earth’s atmosphere. Nitrogen is a constituent element of all living tissues and amino acids. Many industrially important compounds, such as ammonia, nitric acid, and cyanides, contain nitrogen. Nitrogen is a non-metal, with an electronegativity of 3.0. It has five electrons in its outer shell and is therefore trivalent in most compounds.

Nitrogen condenses at 77 K at atmospheric pressure and freezes at 63 K. Liquid nitrogen is a common cryogen. Relevant sites about Nitrogen. About Midwest Micro Lab.

Binary Molecular Compounds of Nonmetals. How does one determine the formula for two non metal elements? Such as Nitrogen and Oxygen. I look at the charges with Nitrogen having -3 and Oxygen having -2. How would I get to zero? How do you build a formula based on those two elements. Why does it equal $\ce $ ? Nonmetals form covalent bonds with other nonmetals, not ionic bonds. This means you can't use ionic bonding rules to figure out what the structure will be. In fact, there is no way to predict the structure - all you could do is propose Lewis structures for various combinations to predict what it could be. This is also why there is a special set of nomenclature rules for molecular compounds - it's not enough to just give the names of the elements, you also have to specify the number of each atom. In your example, if all you are given is N and O, you would have no way of predicting the formula. It could be any one of maybe half a dozen compounds (maybe more). To end up with $\ce $, you would need to know the name of the compound first.

For binary molecular compounds, the naming rules are pretty easy. First, you need to know the prefixes: Then, for each element (starting with the least electronegative one - the one furthest to the left on the periodic table) you just use the prefix in front of the element name. $\ce $ would be called dinitrogen pentoxide . There are two small details. The first is that we don't use "mono" when there is only one atom of the first element. This means that $\ce $ is carbon monoxide rather than monocarbon monoxide. The second is that when an element starts with a vowel and the prefix ends in a vowel, we drop the prefix's ending vowel. This means that we say pentoxide instead of pentaoxide. To find the formula given the name, you just reverse this process. $\ce $ - nitrogen monoxide. $\ce $ - dinitrogen monoxide.

. you get the idea. If you're asking how can you determine a molecular formula when simply given two elements, then there are no hard and fast rules, especially with nitrogen. The only rule I can think of is that molecules, as opposed to ions, are electrically neutral. This still leaves you with plenty of possibilities. Nitrogen is a versatile element and can adopt a variety of oxidation states. So you'll find nitrogen in a variety of compounds in various proportions. Question : 1)A compound contains only carbon, hydrogen, nitrogen, and oxygen. Combustion of 0.157g of the co. 1)A compound contains only carbon, hydrogen, nitrogen, and oxygen. Combustion of 0.157g of the compound produced 0.213g CO 2 and 0.0310g H 2 O. In another experiment, it is found that 0.103g of the compound produces 0.0230g NH 3 . What is the empirical formula of the compound? Hint: Combustion involves reacting with excess O 2 . Assume that all the carbon end up in CO 2 and all the hydrogen end up in H 2 O. Also assume that all the nitrogen ends up in NH 3 in the second experiment. A binary compound between and unknown element E and hydrogen contains 91.27% E and 8.73% H by mass. If the formula of the compound is E 3 H 8 , calculate the atomic mass of E. Best binary sites compound of nitrogen and oxygen While there are many thousands of different chemical compounds there is a very definite system of nomenclature whereby we can name or write chemical formulas for most compounds.

We divide the compounds into two main types – binary compounds and ternary compounds. All true binary compounds contain only two elements. The name of every binary compound ends with “ ide .” Binary compounds come in three types. They are: Type I. the metal forms only one type of cation. Type II. the metal forms two or more types of cations. Type III. contains only nonmetals. We will look at each type, one at a time. Type I Binary Compounds.

For Type I binary compounds the metal present can be found in either Group 1 or Group 2 on the periodic table. The naming system for this type of compound is quite simple and is found below. Rules for naming Type I binary compounds. 1. The cation is always named first and the anion second. 2. A simple cation (obtained from a single atom) takes its name from the name of the element. 3. A simple anion (obtained from a single atom) is named by taking the first part of the element name (the root) and adding the letters “IDE.” 4. Write the name for the compound by combining the names of the ions. Name the compound RbI. · Rb is the chemical symbol for rubidium . · I is the chemical symbol for iodine, whose root is “iod.” Add the “ide” ending to get iodide .

· Put the pieces together to get the name rubidium iodide . Name the compound CaO. · Ca is the chemical symbol for calcium. · O is the symbol for oxygen, whose root is “ox.” Add the “ide” ending to get oxide. · Put the pieces together to get the name calcium oxide. Name the compound Li 3 N. · Li is the chemical symbol for lithium . · N is the chemical symbol for nitrogen, whose root is “nitr.” Add the “ide” ending to get nitride. · Put the pieces together to get the name lithium nitride. Write the formula for potassium sulfide.

· The chemical symbol of potassium is K . K is in the 1 st column of the periodic table, therefore, its oxidation state is +1. · Sulfide is derived from sulfur, whose symbol is S . Its oxidation state is -2. · So far we have… K S. · The total positive charge must balance the total negative charge. Therefore, we need 2 K atoms to give a total positive charge of +2. This balances the -2 charge on the sulfur. · Putting it all together we have K 2 S . Write the formula for magnesium chloride. · The chemical symbol of magnesium is Mg . Mg is in the 2 nd column of the periodic table, therefore, its oxidation state is +2. · Chloride is derived from chlorine, whose symbol is Cl . Its oxidation state is -1. · So far we have… Mg Cl. · The total positive charge must balance the total negative charge. Therefore, we need 2 chlorine atoms to give a total negative charge of -2. This balances the charge on the magnesium. · Putting it all together we have MgCl 2 . NaCl sodium chloride. KI potassium iodide. RbBr rubidium bromide. MgS magnesium sulfide. Sodium fluoride NaF.

Strontium oxide SrO. Beryllium chloride BeCl 2. Cesium sulfide Ce 2 S. Potassium phophide K 3 P. Type II Binary Compounds. For Type II binary compounds the metal present is NOT found in either Group 1 or Group 2 on the periodic table. The naming system for this type of compound is found below. Rules for naming Type II binary compounds. 1. The cation is always named first and the anion second. 2. A simple cation (obtained from a single atom) takes its name from the name of the element. Include a Roman numeral to indicate the oxidation number (charge) on the metal cation. 3. A simple anion (obtained from a single atom) is named by taking the first part of the element name (the root) and adding the letters “IDE.” 4. Write the name for the compound by combining the names of the ions. Name the compound FeCl 2 . · Fe is the chemical symbol for iron. o Fe is not in the 1 st or 2 nd column therefore a Roman numeral is needed in the name. We’ll come back to that shortly.

The Roman numeral is II. · Put the pieces together to get the name iron (II) chloride .

Name the compound PbS 2 . · Pb is the chemical symbol for lead. o Pb is not in the 1 st or 2 nd column therefore a Roman numeral is needed. · S is sulfur, whose root is “sulf.” Add the “ide” ending to get sulfide. · At this point we have lead (??) sulfide . · To find the Roman numeral… § S has a charge of -2. § There are 2 sulfur atoms so…. 2 x -2 = -4. <---- total negative charge. § The total positive charge must be +4. § There is 1 lead atom so… +4 1 = +4. The Roman numeral is IV. · Put the pieces together to get the name lead (IV) sulfide . Write the formula for nickel (III) oxide. · The chemical symbol of nickel is Ni . The oxidation state is +3, as given by the Roman numeral. · Oxide is derived from oxygen, whose symbol is O . Its oxidation state is -2. · So far we have Ni O. · In order to balance the charges we find the least common multiple (LCM) of 3 and 2. The LCM is 6. We need two Ni atoms (+6 +3 = 2) and three O atoms (-6 -2 = 3) to balance the charges. Write the formula for lead (IV) nitride.

· The chemical symbol of lead is Pb . The oxidation state is +4. · Nitride is derived from nitrogen, whose symbol is N . Its oxidation state is -3. · So far we have Pb N. · The LCM of 4 and 3 is 12. We need three Pb atoms (+12 +4 = 3) and 4 N atoms (-12 -3 = 4) to balance the charges. Write the name for iron (II) oxide. · The chemical symbol of iron is Fe . The oxidation state is +2. · Oxide is derived from oxygen, whose symbol is O .

CuCl 2 Copper (II) chloride. PbS lead (II) sulfide. PbS 2 lead (IV) sulfide. Chromium (VI) oxide CrO 3. Nickel (II) bromide NiBr 2. Cadmium (II) iodide CdI 2. Type III Binary Compounds. Type III binary compounds contain no metal atoms. There are two different naming systems for Type III binary compounds: the “old system” and the “new system.” The old system uses prefixes to indicate the number of each atom present and the new system is identical to that used for naming Type II compounds.

It is important to note that only one system can be used at a time. NEVER mix prefixes and Roman numerals. Rules for naming Type III binary compounds: the OLD SYSTEM. 1. The first element in the formula is named first, and the full element name is used. 2. The second element is named as though it were an anion: root + ide. 3. Prefixes are used to denote the numbers of atoms present. (See table below) 4. The prefix mono - is never used for naming the first element. 5. penta 10. deca. Name the compound NO 2 . · N is the chemical symbol of nitrogen . Since there is only one nitrogen atom AND it is the first element the prefix mono is not used. · O is the chemical symbol of oxygen, whose root is ox. Add the ide ending to get oxide. There are two oxygen atoms so we also add the prefix di to get dioxide. · Put the pieces together to get the name nitrogen dioxide . Name the compound N 2 O. · N is the chemical symbol of nitrogen .

Since there are two nitrogen atoms we need to add the prefix di to get dinitrogen. · O is the chemical symbol of oxygen, whose root is ox. Add the ide ending to get oxide . There is only one oxygen atom we add the prefix mono (mono IS used for the second element) to get monoxide . · Put the pieces together to get the name dinitrogen monoxide. Write the formula for carbon tetrachloride. · The chemical symbol of carbon is C . There is no prefix before carbon in the chemical name, therefore, there is only 1 C atom in the chemical formula. · Tetrachloride has the prefix tetra which means there are 4 atoms present. Chloride is derived from chlorine, whose symbol is Cl . Thus, there are 4 Cl atoms in the chemical formula. · Putting it all together we have CCl 4 . Write the formula for dinotrogen pentaoxide. · The prefix di means 2 . Thus there are 2 N atoms in the chemical formula. · The prefix penta means 5. Thus, there are 5 O atoms in the chemical formula. Now let us apply the “new system” to these same compounds. For Type III binary compounds the “new system” is identical to that used to name Type II binary compounds. The advantage to using the new system is that you have one less system to learn.

Rules for naming Type III binary compounds: the NEW SYSTEM. 1. The cation is always named first and the anion second. 2. A simple cation (obtained from a single atom) takes its name from the name of the element. Include a Roman numeral to indicate the oxidation number (charge) on the metal cation. 3. A simple anion (obtained from a single atom) is named by taking the first part of the element name (the root) and adding the letters “IDE.” 4. Write the name for the compound by combining the names of the ions. Name the compound NO 2 . · N is the chemical symbol for nitrogen . o Nitrogen is not in the 1 st or 2 nd column therefore a Roman numeral is needed in the name. · O is the symbol for oxygen, whose root is “ox.” Add the “ide” ending to get oxide . · At this point we have nitrogen (??) oxide .

· To find the Roman numeral… § O has a charge of -2. § 2 oxygen atoms times -2 = -4. <---- total negative charge. § The total negative charge of -4 must be balanced with a total positive charge of +4. § +4 divided by 1 (one N atom) = +4. The Roman numeral is IV. · Put the pieces together to get the name nitrogen (IV) oxide. Name the compound N 2 O. · N is the chemical symbol for nitrogen . o Nitrogen is not in the 1 st or 2 nd column therefore a Roman numeral is needed in the name. · O is the symbol for oxygen, whose root is “ox.” Add the “ide” ending to get oxide . · At this point we have nitrogen (??) oxide . · To find the Roman numeral…. § O has a charge of -2. § 2 oxygen atoms times -2 = -4. <---- total negative charge. § The total positive charge must be +2. § +2 divided by 2 (2 N atoms) = +1. The Roman numeral is I. · Put the pieces together to get the name nitrogen (I) oxide.

Write the formula for carbon(IV) chloride. · The symbol for carbon is C . The oxidation state is +4, as given by the Roman numeral. · Chloride is derived from chlorine. The charge on chlorine is -1 . · So far we have C Cl. · The LCM of 4 and 1 is 4. We need 1 C atom (+4 +4 = 1) and 4 Cl atoms (-4 -1 = 4) to balance the charges. · Putting it all together we have CCl 4 . Write the formula for nitrogen (V) oxide. · The symbol for nitrogen is N . The Roman numeral indicates a charge of +5 . · Oxide is derived from oxygen. The charge on oxygen is -2 . · So far we have N O. · The LCM of 5 and 2 is 10. Therefore, we need 2 N atoms and 5 O atoms to balance the charges. (A. K.A. Compounds that contain polyatomic ions) An ion is an atom with an electric charge (positive or negative). A polyatomic ion is a group of atoms with an electric charge. (Even though it is a group of atoms it acts like it were a single atom.) The names of nearly all polyatomic ions end with the letters – ate or – ite .

Beware three exceptions: cyanide, hydroxide, and peroxide. These ions end with “ide” which can trick into thinking you have a binary compound when you actually have a ternary compound. Naming ternary compounds. Follow the naming systems for Type I and Type II binary compounds but… DON’T CHANGE THE NAME OF THE POLYATOMIC ION . KH 2 PO 4 potassium dihydrogen phosphate. Mn(OH) 2 manganese (II) hydroxide. Calcium hydroxide Ca(OH) 2. Naming Polyatomic Ions that Contain Oxygen. There are many atoms that form several different polyatomic ions with oxygen. The naming system for these ions is based on two things: the most common ion in each series and the number of oxygen atoms compared to the most common ion. The ones that concern us most are ions of phosphorus, sulfur, nitrogen, chlorine, and carbon. Memorize these ions! Naming Polyatomic Ions that Contain Oxygen. One more oxygen that the most common.

per___ate. Most common . ___ate. One less oxygen that the most common. ___ite. Two less oxygens than the most common. hypo___ite. PO 2 3- = hypophosphite. Note: Some of the ions do not exist in the real world, they are written here to show how to use the naming system. For this class, ALL acids begin with H (hydrogen). The names of ALL acids end with the word “acid.” There are two types of acids: those that contain oxygen and those that do not. Naming acids that DO NOT contain oxygen. 1. Take the name of the anion, add the prefix “ hydro ” and change the ending to “ ic .” 2. Add the word “ acid .

” Name the compounds HF. · We know this is an acid because the chemical formula starts with “H.” · Take the name of the anion (fluoride) add the prefix “hydro” and change the ending to “ic”: hydrofluoric. · Finally, add the word “acid.” Name the compound HCN. · We know this is an acid because the chemical formula starts with “H.” · There is no oxygen present so we start with the prefix “hydro.” · Next, take the name of the anion (cyanide) and change the ending to “ic”: hydrocyanic. · Finally, add the word “acid.” Write the formula for hydrobromic acid. · We know the formula starts with “H” because it is an acid. The charge on hydrogen is +1. · We also know that the acid does not contain oxygen because of the “hydro” prefix. · Removing the “hydro” and “ic” leaves us with “brom”, the root of bromine or Br . The charge on bromine is -1. · So far we have H Br. · Balance the charges to get the formula HBr. Write the formula for hydrosulfuric acid. · We know the formula starts with “H” because it is an acid. The charge on hydrogen is +1. · We also know that the acid does not contain oxygen because of the “hydro” prefix.

· Removing the “hydro” and “ic” leaves us with sulfur. The charge on sulfur is -2. · So far we have H S. · Balance the charges to get the formula H 2 S . Naming Acids the DO contain oxygen. 1. Find the name of the polyatomic ion. 2. Change “ate” to “ic” or “ite” to “ous.” 3. Add the word acid. Name the compound HClO 4 . · You know it’s an acid because it starts with H. · ClO 4 - is the perchlorate ion. · Change the “ate” to “ic” and get perchloric. · Add the word acid and get perchloric acid . · You know it’s an acid because it starts with H. · SO 3 2- is the sulfite ion. · Change the “ite” to “ous” and get sulfous.

· Add the word acid and get sulfous acid . o The name is actually sulf ur ous acid, but I will count sulfous acid correct because it follows the naming system. Write the formula for phosphorous acid. · The word acid tells us the first element is H. The charge on H is +1. · We also know it is a ternary acid because the prefix “hydro” (meaning binary acid) is missing. · Change “ous” to “ite” to get phophite. The formula for phophite is PO 3 -3 . · Putting it together and balancing the charges we get H 3 PO 3 . Name each of the following compounds. 13. ZnSe 38. CuCl.

Binary Molecular Compounds of Nonmetals. How does one determine the formula for two non metal elements? Such as Nitrogen and Oxygen. I look at the charges with Nitrogen having -3 and Oxygen having -2. How would I get to zero? How do you build a formula based on those two elements. Why does it equal $\ce $ ? Nonmetals form covalent bonds with other nonmetals, not ionic bonds. This means you can't use ionic bonding rules to figure out what the structure will be. In fact, there is no way to predict the structure - all you could do is propose Lewis structures for various combinations to predict what it could be. This is also why there is a special set of nomenclature rules for molecular compounds - it's not enough to just give the names of the elements, you also have to specify the number of each atom. In your example, if all you are given is N and O, you would have no way of predicting the formula. It could be any one of maybe half a dozen compounds (maybe more). To end up with $\ce $, you would need to know the name of the compound first. For binary molecular compounds, the naming rules are pretty easy. First, you need to know the prefixes: Then, for each element (starting with the least electronegative one - the one furthest to the left on the periodic table) you just use the prefix in front of the element name. $\ce $ would be called dinitrogen pentoxide .

There are two small details. The first is that we don't use "mono" when there is only one atom of the first element. This means that $\ce $ is carbon monoxide rather than monocarbon monoxide. The second is that when an element starts with a vowel and the prefix ends in a vowel, we drop the prefix's ending vowel. This means that we say pentoxide instead of pentaoxide. To find the formula given the name, you just reverse this process. $\ce $ - nitrogen monoxide. $\ce $ - dinitrogen monoxide. . you get the idea. If you're asking how can you determine a molecular formula when simply given two elements, then there are no hard and fast rules, especially with nitrogen. The only rule I can think of is that molecules, as opposed to ions, are electrically neutral. This still leaves you with plenty of possibilities. Nitrogen is a versatile element and can adopt a variety of oxidation states.

So you'll find nitrogen in a variety of compounds in various proportions. Nitrogen Testing. Nitrogen Analysis & Techniques Used: The method in use is an upgraded form of that originally researched in Switzerland and marketed by various firms in the US. Fundamentally, the scheme involves combustion of a sample in ultra-pure oxygen at 990 deg C in a closed system. The products (gasses) are swept through copper to remove excess Oxygen and silver salts to remove halogens, phosphorus, and sulfur. Since the heat conductivity depends upon it’s composition, the mixture of remaining gasses is sensed. The H2O is removed. Later the CO2 is removed and finally only N2 remains. Sensing is done after each removal. The instrument is calibrated using various standards from the NIST. Thus all three elements can be determined in one run from the same sample selection. Running one sample at a time enables us to check for inorganic residue post combustion.

Interferences are very few. Very high fluorine levels (>60%) can cause high nitrogen results. This can be circumvented. The optimal sample size depends upon theory. It is always best that the analyst knows all elements present (the molecular formula). If completely unknown, the operator will select about 2 mg for analysis. This equipment does well in the analysis of air-sensitive samples. These samples are sealed under nitrogen (in a controlled atmosphere) in preweighed capsules. After removal from the glove box, the capsule is reweighed and quickly inserted into the analyzer. This “special handling” process can be done in less than 4 minutes thus minimizing any degradation of the sample.

There is a correction made for the increased nitrogen blank from the glove box gas. Atomic weight 14.00, Atomic Number 7, Melting Point -210 C, Boiling Point -195.79 C. Nitrogen is a chemical element which has the symbol N and atomic number 7 in the periodic table. Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78.08% percent of Earth’s atmosphere. Nitrogen is a constituent element of all living tissues and amino acids. Many industrially important compounds, such as ammonia, nitric acid, and cyanides, contain nitrogen. Nitrogen is a non-metal, with an electronegativity of 3.0. It has five electrons in its outer shell and is therefore trivalent in most compounds. Nitrogen condenses at 77 K at atmospheric pressure and freezes at 63 K. Liquid nitrogen is a common cryogen. Relevant sites about Nitrogen. About Midwest Micro Lab.
