Question

Name Date Class Redox Worksheet #1 - Assigning Oxidation Numbers Instructions: A. Assign oxidation numbers to all elements in both reactants and products. B. Determine if two elements change in oxidation number. If YES, the reaction is a REDOX reaction. Answer "C" and "D". If NO, the reaction is not a redox reaction. Go to the next example. C. Determine which element is oxidized and which element is reduced. D. Determine which element is the oxidizing agent and which element is the reducing agent. E. In the left margin, indicate the type of reaction (in addition to redox) each one is. 1. _ CaCO → - Cao + CO, 2. -C + - , — CO2 3. __C - 0→ 4. — H - Br2 → - HBr
