Answer 1

he heat evolved or absorbed in a chemical process is the same whether the process takes place in one or in several steps.
Thermal equations Hess's law energy level diagram
A + B = AB, dH1
AB + B = AB2, dH2
then,
A + 2 B = AB2, dH1 2 = dH1 + dH2


======= A + 2 B

dH1 2 | ===== AB + B
| | dH2
======= AB2
