Consider the following reaction: 2Mg(s) + O_2(g) rightarrow 2 MgO(s) delta H = - 1204 kJ Is this reaction exothermic or endothermic? Calculate the amount of heat transferred when 3.55 g of Mg(s) reacts at constant pressure. How many grams of MgO are produced during an enthalpy change of -234 kJ? How many kilojoules of heat are absorbed when 40.3 g of MgO(s) is decomposed into Mg(s) and O2(g) at constant pressure?
