[b]1. The problem statement, all variables and given/known data
Why is it so important to show state symbols when writing chemical equations involving enthalpy changes?
[b]3. The attempt at a solution
I guess:
from the thermochemical eqn deltaH=Sigma[H_{f}][products]-Sigma[H_{f}][reactants];
because the enthalpy of formation of a substance in different states is different,then this serves as a reason to denote the state symbols. Am I correct?monkoej@gmail.com
