The answer is zero (0).

Helium has zero valancy.

Because it belongs to the group of noble gases and the valance shells of noble gases are completely filled. So, they have no tendency to loose or gain electrons.

That is why helium has zero valancy

Explanation:

Calcium carbide reacts with water to yield acetylene gas and calcium hydroxide as follows;

CaC2(s)+2H2O(g)⇋Ca(OH)2(s)+C2H2(g)

This now shows us that the equation as written in the question is wrong. Since the equation for the reaction of calcium carbide and water as shown in the question is wrong, the equation can not be balanced.
