The oxidation value (number) of C atom in carbide (not corbide) is -1, and of Ca always +2. This makes one Ca reacting with two C atoms in forming CaC2.
Calcium Carbide is a common but improper name for CaC2.
It's proper name is Calcium Acetylide.
In Calcium Acetylide there are three covalent bonds joining the Carbon atoms, and
the forth bond of each Carbon go to Calcium forming an ionic bond.
Crystal structure :
The common crystalline form at room temperature is tetragonal, a distorted rock salt structure with the C22− units lying parallel.

How many grams of water are needed to react with 492 g of calcium carbide?
Assuming pure calcium carbide: CaC2 + 2 H2O → C2H2 + Ca(OH)2 Molar mass of CaC2 = 64.1 Molar mass of water =18 ∴ no mol of CaC2 = 492/64.1=7.68mol ∴ no mol H2O =2*7.68=15.35mol ∴mass H2O = 15.35*18 = 276.3g of water
