Chapter 5, Problem 5.41(choose chapter or problem)
Consider the following reaction: 2 Mg(s) + 02{g) -> 2 MgO(s) t.H = -1204 kJ (a) Is this reaction exothermic or endothermic? (b) Calculate the amount of heat transferred when 2.4 g of Mg(s) reacts at constant pressure. (c) How many grams of MgO are produced during an enthalpy change of -96.0 kJ? (d) How many kilojoules of heat are absorbed when 7.50 g of MgO(s) is decomposed into Mg(s) and 02{g) at constant pressure?
