Calcium carbide, CaC2, can be produced in an electric furnace by strongly heating calcium oxide (lime) with carbon. The unbalanced equation is CaO(s)+C(s) → CaC2(s)+CO(g). Calcium carbide is useful because it reacts readily with water to form the flammable gas acetylene, C₂ H2, which is used extensively in the welding industry. The unbalanced equation is CaC₂ (s) + H₂O(l) → C₂ H₂(g) + Ca(OH)₂ (s). What mass of acetylene gas, C₂ H₂, would be produced by complete reaction of 3.25 g of calcium carbide? 9 C₂ H₂
