# How does calcium carbide react with water? How much acetylene product will be obtained?

$C a {C}_{2}$ dissolves in water to give $C a {\left(O H\right)}_{2}$ and 1 equiv acetylene gas...........
$C a {C}_{2} \left(s\right) + 2 {H}_{2} O \left(l\right) \rightarrow C a {\left(O H\right)}_{2} \left(a q\right) + H C \equiv C H \uparrow$
