Web290 g Aluminum reacts with sulfuric acid to produce aluminum sulfate and hydrogen gas. How many grams of aluminum sulfate would be formed if 250g H2SO4 completely react … WebWith Hess's Law though, it works two ways: 1. You use the molar enthalpies of the products and reactions with the number of molecules in the balanced equation to find the change in enthalpy of the reaction. That's what you were thinking of- subtracting the change of the products from the change of the reactants. 2.
