Topics include isotopes, drawing a rates graph, a sulfuric acid titration, reacting masses, alkenes, alcohols and carboxylic acids, and measuring the energy from a burning fuel. There are two open-ended questions: why carbon dioxide and silicon dioxide behave so differently, and whether ethanol from sugar cane is a “greener” fuel.
