CHAPTER 13; GAS STOICHIOMETRY
Answer the following
questions. Remember to look to see if your conditions are at STP or not.
1. Assume that 5.60 L of hydrogen gas at STP reacts with copper (II) oxide according to the following
balanced equation: CuO(s) + H2(g) -7 Cu(s) + H20(g). How many grams of copper are produced?

of hydrogen gas are collected at STP, how many grams of iron (II) sulfate are also produced?
