CaC2(s)+2H2O(l)→HC≡CH(g)↑⏐+Ca(OH)2(s)

Explanation:

Now this is simply an acid base reaction, and in fact this reaction was the basis of the old miners' head lamp, where some crushed calcium carbide was moistened with a few drops of water, and the acetylene evolved was combusted:

HC≡CH(g)+52O2(g)→2CO2(g)+H2O(s)
