Q □ G O Chemical Reactions Reaction sequence stoichiometry 0/5 Matthe 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(g) + 3H2(g) → 2 NH, (g) In the second step, ammonia and oxygen react to form nitric acid (HNO3) and water: NH2(g) + 202(g) → HNO3(g) + H2O (g) Suppose the yield of the first step is 62.% and the yield of the second step is 87.%. Calculate the mass of hydrogen required to make 10.0 kg of nitric acid. Be sure your answer has a unit symbol, if needed, and is rounded to 2 significant digits. ☐ x10 Explanation Check OC 2024 McGraw Hill LLC. All Rights Reserved. Terms of Use | Privacy…
