Calcium carbide (CaC2) reacts with water to form acetylene ...

Solved: Calcium carbide (CaC2) reacts with water to form acetylene (C2H2) gas and calcium hydroxide (Ca(OH)2). If the ΔH for: CaC2(s) + 2H2O(l) = Ca(OH)2(s) + C2H2(g) is -127 kJ, then what is the enthalpy of formation for calcium carbide? The ΔH of formation for H2O(l), Ca(OH)2(s) and C2H2(g) are -286, -986, 227 kJ/mol respectively. The units are kJ.
