enthalpy and heat change
You people heard about hess law means that sum of all enthalpies of chemical reactions takes place but why we only call sum of all enthalpies?
B----C dH2 HESS LAW
DH = dH1 + dH2
B----C dQ2 ?
DQ = dQ1 + dQ2
In the above representations one is associated with enthapy and another is heat
whethe second one is valid or not?if so why?
