1. The combustion of sugar produces carbon dioxide and water according to the following equation. CH1206 (9) + 6 02 (g) 6 CO2 (g) + 6 H20 (8) a) Is this equation balanced? b) If 50.0 g of sugar is burned, how many moles of CO2 will be produced? c) How many grams of sugar are needed to produce 26.0 g H20? d) How many moles of O2 (g) are needed to burn 50.0 g of sugar? 2. Consider the reaction: 4 NH3 + 702 + 4NO2 + 6 H2O a) How many grams of O2 are required to react with 22.8 g of ammonia? b) How many grams of NO2 will be produced from 22.8 g of ammonia? c) If 22.8 g of ammonia produces 46.3 g of NO2, what is the percent yield? 3. How many grams of phosphoric acid will be produced when 135.0 g of P4010 is mixed with 90.0 g of water and the reaction goes until one of the reactants is completely used up? P4010 + 6 H20 4 H3PO4 4. Nitric acid and nitrogen monoxide are produced when nitrogen dioxide reacts with water. 3 NO2 + H20 2 HNO3 + NO If 300. g of NO2 are mixed with 100. g of H20 and the reaction goes until one of the reac- tants is completely used up, determine the following. a) Which is the limiting reagent? b) How many grams of nitric acid are produced? c) How many grams of each of the reactants, NO2 and H20, are left over? d) What is the percent yield of nitric acid if 246. g of HNO3 is produced? 5. Consider the following reaction: 3 Cu + 8 HNO3 3 Cu(NO3)2 + 2 NO + 4 H20 a) If 75.0 g of Cu reacts with 75.0 g HNO3 to produce 8.50 g H2 calculate the percent yield. b) If 75.0 g of Cu reacts with 75.0 g HNO3 to produce 8.50 g H20, how many grams of NO will be produced
