Name the substance oxidised and the substance reduced, and also identify the oxidising agent and reducing agents in the following reactions :
(a) `3MnO_(2) +4Al to 3Mn +2Al_(2)O_(3)`
(b) `Fe_(2)O_(3) + 3CO to 2Fe + 3CO_(2)`
(c) `SO_(2) + 2H_(2)S to 3S +2H_(2)O`

AI Generated Solution

To solve the question, we need to analyze each reaction to identify the substances that are oxidized and reduced, as well as the oxidizing and reducing agents. Let's go through each reaction step by step. ### (a) Reaction: `3MnO2 + 4Al → 3Mn + 2Al2O3` 1. **Identify Oxidation and Reduction:** - **Oxidation:** Aluminum (Al) is oxidized as it goes from 0 oxidation state to +3 in Al2O3. - **Reduction:** Manganese dioxide (MnO2) is reduced as manganese (Mn) goes from +4 in MnO2 to 0 in elemental Mn. ...
