Consider the following reaction:
(a) Is this reaction exothermic or endothermic?
(b) Calculate the amount of heat transferred when 3.55 g of Mg(s) reacts at constant pressure.
(c) How many grams of MgO are produced during an enthalpy change of -234 Kj?
(d) 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?
