The Balanced Equation: CaC2 + 2H20 --> Ca (OH)2 + C2H2 ; It's given that there is 100g of H20 and 100g of CaC2. 1) Divide 100g CaC2 by the molar mass of CaC2. The molar mass of CaC2 is 64.10 g/mol (found by adding Ca's mass of 40.08 to 2*12.01, where the 2 comes from the presence of 2 carbon atoms and 12.01 is carbon's mass).

The bond between the two carbon atoms is covalent. However, the bond between calcium and the CX2X2− C X 2 X 2 − fragment is ionic. Therefore, calcium carbide can be classified as an ionic compound. If you dig deeper, you may come across the crystal structure of calcium carbide; see for example the following taken from Wikipedia:
