Reaction Information. Mg + O2 = MgO - Chemical Equation Balancer. Enthalpy of Reactions: The enthalpy of a chemical reaction pertains to the heat involved per amount of a substance involved in a reaction. Answers: 3 Show answers- Another question on Chemistry. Mg(OH)2 (s) ----> MgO (s) + H2O (l) delta H = 37.1 KJ Reaction Type. O 2 + 4 e-2 O 2- The stoichiometry of a reaction is the ratio. So the products are MgO and Cl2. That also suggests that 2 moles of Mg can react with 1 mole of O2. What's unusual, however, is that magnesium is reactive enough to be combusted and oxidized in a reaction with carbon dioxide: 2 Mg + CO 2 -> 2 MgO + C. Under normal combustion/oxidation circumstances, oxygen is the reactant. this I agree with. If you do not know what products are enter reagents only and click 'Balance'.
