What would be the three equations that cancel correctly for Hess Law for the following reaction for Magnesium oxide that you would have Mg(s) + 1/2 O2(g) = MgO(s) ? Would the change in heat be a negative or a positive? what would be the final net reaction? I am confused would you then have four equations
