    isn't it change in products minus change in reactants?
    Q={change in heat ofproducts}- {change in heat of reactants}
    just wanna make sure:)

    Yea, you are right, but just dont get your letters confused! Q stands for Rxn quotient while delta H stands for enthalpy change. The only reason you would need to know what each letters mean is probably if they ask to calculate Q, then you might think its enthalpy change but its really asking rxn quotient!!

    Also, since we are talking about Q, know what happens when Qsp>Ksp, or vice versa. Also know what happens when Q>Keq, etc. Just some stuff you might want to know since its more based on conceptul now!!

    Hope this helps!
