Problem 43E

Enthalpy (Sections)

Consider the following reaction:

2 Mg(s) + O2(g) →2 MgO(s) ΔH =–1204 kJ

(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?
