Unformatted text preview: 1. a) Write a balanced chemical equation for the complete reaction of gaseous nitrogen and gaseous hydrogen to produce the only product, gaseous ammonia. N 2 (g) + 3 H 2 (g) = 2 NH 3 (g) (It is important for the students to recognize which atoms form diatomic molecules, and the difference between ammonia (NH 3 ) and ammonium (NH 4 + ).) b) At constant pressure and temperature, 2.4 L of nitrogen reacts with 7.2 L of hydrogen. If all the nitrogen and hydrogen are consumed, what volume of ammonia, at the same temperature and pressure, will be produced? Avogadros hypothesis Mole ratios in the chemical equation will be the volume ratios for the gases if they are at the same temp. and pressure. Therefore, there are 2 ways to answer this problem: 2.4 L N 2 (2 mole NH 3 /1 mol N 2 ) = 4.8 L NH 3 OR 7.2 L H 2 (2 mol NH 3 /3 mol H 2 ) = 4.8 L NH 3...
