Question

When calculating the AH of a reaction, why is it important that you include the correct stale symbols in your balanced chemical equation?

Answer 1

Answer: c. so that you use the correct energy states

Step-by-step explanation:

Enthalpy is the energy release or energy produced when a chemical reaction is carried out.

Enthalpy change is calculated by substracting the energy of reactants from the energy of products.

`\Delta H=H_(products)-H_(reactants)`

As the energies are different for different states and thus the correct stale symbols in your balanced chemical equation must be given so that we use the correct energy values.
