Given the following data C2H2(g) 5 2 O2(g) 2CO2(g) H2O(l) H 1300 kJ C(s) O2(g) CO2(g) H 394 kJ H2(g) O2(g) H2O(l) H 286 kJ calculate H for the reaction 2C(s) H2(g) C2H2(g)

Question: Given the following data: C2H2(g) + 5/2 O2(g) 2CO2(g) + H2O(l) H = 1300. kJ C(s) + O2(g) CO2(g) H = 394 kJ

Given the following data:
C2H2(g) + 5/2 O2(g) → 2CO2(g) + H2O(l) ΔH = –1300. kJ
C(s) + O2(g) → CO2(g) ΔH = –394 kJ
H2(g) + ½ O2(g) → H2O(l) ΔH = -286 kJ
calculate ΔH for the reaction 2C(s) + H2(g) → C2H2(g)
