under what conditions does q=delta H?
and how would you use it in an equation?

q only equals delta H when the reaction is occurring at a constant pressure that involves solids and/or liquids. This is because P times delta V is insignificant due to the constant pressure and the volume of the reactants equals the volume of the products.
