Mg (s) + 1/2O₂(g) → MgO (s) (1) Equation 1 can be obtained by combining equations (2), (3), and (4): MgO (s) + 2 HCl (aq) → MgCl2 (aq) +H₂O (1) Mg (s) + 2 HCl (aq) → MgCl₂ (aq) + H₂ (g) H₂ (g) + O2(g) → H₂O (1) Before lab, you should combine and rearrange equations 2, 3, and 4 to obtain equation (1). The heats of reaction for equations 2 and 3 will be determined in this experiment. The AH for equation 4 is -285.8 kJ/mol. (2) (3) €
