The following equation shows the formation of magnesium oxide from magnesium metal. Which statement is correct for this reaction?
2Mg(s) + O2(g) --> 2MgO(s) ΔH = -1204 kj
1204 kJ of energy are released for every mole of magnesium reacted
602 kJ of energy are released for every mole of oxygen reacted
602 kJ of energy are absorbed for every mole of magnesium oxide formed
1204 kJ of energy are released for every two moles of magnesium oxide formed
