Question 1

Coal contains an impurity that reacts with oxygen during the combustion process, producing oxides that are major environmental pollutants. This impurity is:
◦ acid rain
◦ nitrogen
◦ sulfur
◦ carbon dioxide
◦ peat

Question 2

Combine the reactions:

P₄(s) + 6 Cl₂(g)  → 4 PCl₃(g)  Δ_rH°₂₉₈ = -1225.0 kJ/mol
PCl₃(g) + 3 H₂O(l)  → H₃PO₃(aq) + 3 HCl(g)  = -853.5 kJ/mol
2 H₂(g) + O₂(g)  → 2 H₂O(l)  = -571.5 kJ/mol
H₂(g) + Cl₂(g)  → 2 HCl(g)  = -184.9 kJ/mol

to obtain the reaction: P₄(s) + 6 H₂(g) + 6 O₂(g) → 4 H₃PO₃(aq).
What is the value of Δ_rH°₂₉₈ for this reaction?
◦ -2465.1 kJ/mol
◦ -6958.6 kJ/mol
◦ -2834.9 kJ/mol
◦ -9177.4 kJ/mol
◦ 8605.9 kJ/mol
