Question

Explain Jesse's law of constant heat sumation with an example

Answer 1

Answer:

Hess's law of heat summation states that the total enthalpy change during a reaction is the same whether the reaction takes place in one step or in several steps. For example, in the above diagram, ΔH1=ΔH2+ΔH3=ΔH4+ΔH5+ΔH6 . In Hess's Law calculations, you write equations to make unwanted substances cancel out.
