Acetylene (C2H2) is a small organic molecule used in the industrial preparation of many other molecules and also in welding.Acetylene is made from calcium carbide (CaC2) and water and produces acetylene and calcium hydroxide.Which of the following choices is the correct balanced chemical equation for the preparation of acetylene?
A) CaC2 + H2O → CaO + C2H2
B) CaC2 + H2O → Ca(OH) 2 + C2H2
C) CaC2 + 2 H2O → Ca(OH) 2 + C2H2
D) CaC2 + 2 H2O → CaO + C2H2 + H2O
E) 2 CaC2 + H2O → Ca(OH) 2 + 2 C2H2
