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…

O CHEMICAL REACTIONS Anniston V Solving for a reactant in solution 1/5 One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 200. mL sample of groundwater known to be contaminated with iron(II) chloride, which would react with silver nitrate solution like this: FeCl,(aq) + 2 AgNO3(aq) → 2 AgCl(5) + Fe(NO3),(aq) 2 The chemist adds 11.0 mM silver nitrate solution to the sample until silver chloride stops forming. She then washes, dries, and weighs the precipitate. She finds she has collected 8.9 mg of silver chloride. ol. Calculate the concentration of…
