Learning Task 1 Write TRUE if the statement is correct and FALSE if the statement is wrong. 1. Iron will rust if only oxygen, but no water, is present. 2. Reduction occurs at the cathode in an electrical cell. 3. Galvanic cells use chemical reactions to produce electricity. 4. Electroplating is commonly used to improve the appearance of metals or to prevent corrosion. 5. Tarnishing of silverware and greening of copper, bronze and brass involves electrochemical process. Learning Task 2 Fill in the blanks. Supply the correct word from the word bank. oxygen alloy chromium corrodes sacrificial first flake stainless water less oxidation oxide zinc oil paint reactive rusting and Iron or steel to form an iron reaction.
