Homework Answers
The exercise in question can be summarized as follows::
So if we apply the Hess law and carry out a sum of reactions 1
and 2, as well as an exchange of products to reactants and
reactants to products in reaction number 2 with their respective
sign change in enthalpy you have to:
Then the reaction change enthalpy for the third equation is 85,5 KJ
