Consider the following data:
 
ΔH° (kJ)
Ca(s) + 2C(graphite) → CaC2(s)
-62.8
Ca(s) + O2(g) → CaO(s)
-635.5
CaO(s) + H2O(l) → Ca(OH)2(aq)
-653.1
C2H2(g) + O2(g) → 2CO2(g) + H2O(l)
-1300
C(graphite) + O2(g) → CO2(g)
-393.51
Use Hess' law to find the change in enthalpy at 25°C for the following equation:
              CaC2(s) + 2H2O(l) → Ca(OH)2(aq) + C2H2(g)
