combustion

Postby Michelle Chernyak 1J » Sun Feb 04, 2018 8:06 pm

This question maybe really stupid but is it possible to just subtract the enthalpies of formation of the products from the enthapies of formation of the reactants when doing a combustion problem?

Yes, because enthalpy is a state function.

Yes, the equation was provided in the book and by Dr. Lavelle.

Yes you can subtract the enthalpies of formation of reactants from the enthalpies of formation of reactants since enthalpy is a state function (path is independent from final and initial state).

Yes, state properties are additive!
