Molecular Formula Practice
1. Calcium carbide, CaC2 reacts with water to form acetylene.
CaC2(s) + 2H20(l) C2H2(g) + Ca(OH)2(s)
a. How many grams of water are needed to react with 485 g of calcium carbide?
b. How many grams of CaC2 could make 23.6 g C2H2?
c. If 55.3 g Ca(OH)2 are formed, how many grams of water reacted?
