Chapter 5, Problem 36P(choose chapter or problem)
Problem 36PConsider the following balanced thermochemical equation for the decomposition of the mineral magnesite:
MgCO3(s) → MgO(s) + CO2(g) Δ Hrxn = 117.3 kJ
(a) Is heat absorbed or released in the reaction?
(b) What is Δ Hrxn for the reverse reaction?
(c) What is Δ H when 5.35 mol of CO2 reacts with excess MgO?
(d) What is Δ H when 35.5 g of CO2 reacts with excess MgO?
