Use the chemical equations below to answer the questions on stoichiometry. These calculations give theoretical yields, or determine the amount of reactant needed to make a given amount of product. Don't forget to balance each equation, and show your work. For liquids, you may need to find density H-C C-H(g) O2 (g) H2O () 1. 4 CO2 (g) + + a. Given 0.72 moles of oxygen gas, how many moles of water can form? b. Starting with 55.2 grams of...

POGIL-Stoichiometry How do chemists use balanced chemical equations? got bit D 23 mosquitoes? 10 He got Mol-aria Why? Chemists use balanced chemical equations as a basis to calculate how much reactant is needed or product is formed in a reaction. This is called Stoichiometry- (stoi-key-ah-meh-tree) Another way of looking at it is using the mole ratio from the balanced equation and information about one compound in the reaction to determine information about another compound in the equation. A mole ratio...
