Stoichiometry Practice Problems Be sure to balance all equations before you start calculating! Answer key is at the end. 1) Lithium hydroxide reacts with hydrobromic acid to produce lithium bromide and water. If you start with ten grams of lithium hydroxide‚ how many grams of lithium bromide will be produced? 2) Ethylene (C2H4 ) reacts with oxygen gas to produce carbon dioxide and water. If you start with 45 grams of ethylene‚ how many grams of carbon dioxide will be produced?
