Expert Answer

Step 1

The Hess's law can be described as the law that will be used to calculate the value of the change in enthalpy for the net chemical reaction will be equivalent to the addition of all the change in enthalpy of the single chemical reactions into which the net chemical reaction will be divided.

Step 2

The equation for the reaction (1) of M and HCl is shown below:
