In Experiment 18, you learned about the additivity of reaction heats as you confirmed Hess's Law. In this experiment, you will use this principle as you determine a heat of reaction that would be difficult to obtain by direct measurement—the heat of combustion of magnesium ribbon. The reaction is represented by the equation (4) Mg(s) + 1/2O2(g) MgO(s) This equation can be obtained by combining equations (1), (2), and (3): (1) MgO(s) + 2 HCl(aq) + MgCl2(aq) + H20(1) (2) Mg(s) + 2 HCl(aq) MgCl2(aq) + H2 (g) (3) H2(g) + 1/2O2(g) H2O(1) opy
In the space provided below, combine equations (1), (2), and (3) to obtain equation (4). (1) (2) (3)
