Basically its last question of my prep and I have tried but nothing makes sence, please can someone help me.
calculate the standard enthalpy change in the reaction
SO2 + 2H2S = 3S + 2H20
The standard enthalpy of cumbustion of sulphur is -297 and the standard enthalpies of formation of hydrogen sulpide is -20.1 and standard enthalpy of formation of water is -286
Enthalpy Question Im really confused!! Watch

Assume standard enthalpy of combustion of sulfur = standard enthalpy of formation of SO2

And don't forget enthalpy of formation for elements is 0!
Use delta H= (delta Hf final) - (delta Hf initial)
