The combustion of liquid ethanol produces carbon dioxide and water. After 4.2 ml of ethanol (density = 0.789 g/ml) was allowed to burn in the presence of 12.5 g of oxygen gas, 3.10 ml of water (density = 1.00 g/ml) was collected.Determine the limiting reactant. ( : Write a balanced equation for the combustion of ethanol.Determine the theoretical yield of H2O. Determine the percent yield for the reaction.
