Interpret results from rusting experiments. (Chemistry only)

In the subtopic Corrosion and its prevention, this learning objective focuses on interpret results from rusting experiments. (Chemistry only). Within Using materials, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include chemistry only and rusting. rusting means the corrosion of iron caused by chemical reactions with oxygen and water. Avoid students often confuse the presence of rust with the absence of rusting conditions, failing to recognize that rusting requires both air and water; instead to fix this, students should remember that rusting occurs only when both air and water are present, and they should analyze experimental results to identify these conditions. For exam answers, review the setup and results of rusting experiments to identify the role of air and water in the rusting process.
