Calculate the heat evolved per mole on combustion of each substance to yield CO2(g) and H2O(g).
Hey there! So you can get the enthalpy of combustion from the given enthalpy of formation Using this formula:
Assitional standard enthalpies of formation:
CO2 = -393.5 kJ/mol
H2O = -241.8 kJ/mol
O2 = 0 kJ/mol
I'll do the propyne (C3H4) step by step, the other will just be similar. Just get the balanced chemical reaction for each gas.
I hope this helps!
THANK YOU SO MUCH
