Answer: The ΔH of the reaction if 51.3 g of 
reacts with excess 
to yield 1387.6 kJ is 432.27kJ
Explanation:
To calculate the moles, we use the equation:
moles of
As is present in excess, is the limiting reagent as it limits the formation of product.
If 3.21 moles of methane releases heat = 1387.6 kJ
Thus 1 mole of methane release=
