⦁ (12 pts) Calcium carbide, CaC2, reacts with water to form calcium hydroxide and the flammable gas acetylene, C2H2. (Historically, this reaction was used for bicycle lamps and miner’s helmets!) When 96.5 g of calcium carbide was reacted with 52.3 g of water according to the reaction below, 99.3 g of calcium hydroxide was produced. What was the percent yield of this reaction? CaC2 + 2H2O Ca(OH)2 + C2H2
