Calculate the change in the enthalpy of the reaction.

Question

C4H4(g)+2H2(g)===>C4H8(g)

Use the following:
change in enthalpy of combustion for: C4H4=-2341 kJ mol-1
H2=-286 kJ mol-1
C4H8=-2755 kJ mol-1

Answer 1

Your question isn't clear. I assume one equation is
C4H4 + O2 ==>CO2 + H2O
but I don't now what H2 = ?? and C4H8 = ?? mean.

Answer 2

Umm... the H2 is hydrogen and C4H8 is Carbon 4, Hydrogen 8. If I knew what it meant than I wouldn't be asking for help, would I?!?!?

Answer 3
