The second Paadama model paper in the format of the G.C.E. (A/L) Chemistry Paper II. Part A: answer all four structured questions (100 marks each). Parts B and C: answer four essay questions, two from each part (150 marks each). R = 8.314 J K⁻¹ mol⁻¹, F = 96 500 C mol⁻¹, Kw = 1.0 × 10⁻¹⁴ mol² dm⁻⁶ at 25 °C, molar volume of a gas at 273 K and 1.01 × 10⁵ Pa = 22.4 dm³ mol⁻¹. Relative atomic masses: H 1, C 12, N 14, O 16, Na 23, Mg 24, S 32, Cl 35.5, Fe 56, Ag 108. Each question has a model answer showing where the marks go.
