Senior Three Chemistry Holiday Work: Carbon Compounds, Oxides and Atomic Structure

This set of structured chemistry questions is headed as holiday work for Senior Three learners. It starts with preparing salts and the reactions of calcium carbonate with acids and heat. It then covers how carbon monoxide is prepared in the laboratory and how it reduces metal oxides. Other questions deal with atomic number, mass number, electron configuration, valency and chemical bonding. Learners also choose methods for separating given mixtures, classify oxides, interpret a table of physical properties, and describe what happens when copper(II) sulphate crystals are heated. Mark allocations appear beside many parts. The questions suit revision during the school holidays or practice before a test.
