Question

Why is enthalpy of reaction product minus reactant?

Answer 1

$\huge\mathfrak\red{HeyAa..!}$

It is true that Enthalpy of reaction (general) is calculated as enthalpy of products minus enthalpy of reactants: In the case that you are GIVEN the heat of combustion of each species in your reaction, you do the reverse: This can be explained simply by Hess' Law.
