Question 1

Given the thermochemical equation 2SO2(g) + O2(g) → 2SO3(g),  ΔH°rxn= –198 kJ/mol, how much heat is evolved when 600. g of SO2 is burned?
◦ 5.46 × 10–2 kJ
◦ 928 kJ
◦ 1.85 × 103 kJ
◦ 3.71 × 103 kJ
◦ 59,400 kJ

Question 2

Glycine, C2H5O2N, is important for biological energy.  The combustion reaction of glycine is given by the equation
         4C2H5O2N(s) + 9O2(g) → 8CO2(g) + 10H2O(l) + 2N2(g)       ΔH°rxn = –3857 kJ/mol
Given that ΔH°f[CO2(g)] = –393.5 kJ/mol and ΔH°f[H2O(l)] = –285.8 kJ/mol, calculate the enthalpy of formation of glycine.
◦ –3,178 kJ/mol
◦ –964 kJ/mol
◦ –537.2 kJ/mol
◦ –268.2 kJ/mol
◦ 2,149 kJ/mol
