When 2 mol of solid magnesium (Mg) combines with 1 mole of oxygen gas (O2), 2 mol of solid magnesium oxide (MgO) is formed and 1204kJ of heat is released. Write the thermochemical equation for this combustion reaction.

  • Chemistry -

    2MgO + O2 ==> 2MgO delta H = -1204 kJ.
    becomes
    MgO + 1/2 O2 ==> MgO delta H = -602 kJ/mol for the thermochemical equation.
