Nitric acid is often manufactured from the atmospheric gases nitrogen and oxygen, and hydrogen prepared by reforming natural gas, in a two-step process. In the first step, nitrogen and hydrogen react to form ammonia: N2(3) + 3H,(g) 2 NH, (g) In the second step, ammonia and oxygen react to form nitric acid (HNO,) and water: NH, (g) + 20,(g) - HNO, (g) + H,0 (g) Suppose the yield of the first step is 79.% and the yield of the second step is 70.%. Calculate the mass of nitrogen required to make 6.0 kg of nitric acid. Be sure your answer has a unit symbol, if needed, and is rounded to the correct number of significant digits.

A3) Balance the following equation. You must enter a number in every blank. Fe(s) + O2lg) → Fe3O4(s)
