Calculate the amount of heat transferred when 21.0 of CH3OH(g) is decomposed by this reaction at constant pressure.

Answer 1

So far my equation is 21 gCH3OH*(1 mol/32.01CH3OH)

Answer 2

You don't show a reaction.

Answer 3

2CH3OH(g)->2CH4(g)+O2(g)
Change in H=252.8 kJ

Answer 4

21 gCH3OH*(1 mol/32.01CH3OH)*(252.8/1 mol)

Answer 5

The answer is 82.8 kJ
