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
