a)
Interpretation:Below
Concept introduction:Change in oxidation number of a molecule, ion or atom in reaction is termed as redox reaction. It occurs due to electron transfer between two species.
Oxidizing agent is substance that gains its electrons. It reduces itself and oxidizes other species in
Categorization of redox reactions:
1. Combination redox reaction
2. Decomposition redox reaction
3. Displacement redox reaction
b)
Interpretation:Below redox reaction should be balanced and classified as combination, decomposition or displacement reaction.
Concept introduction:Change in oxidation number of a molecule, ion or atom in reaction is termed as redox reaction. It occurs due to electron transfer between two species.
Oxidizing agent is a substance that gains its electrons. It reduces itself and oxidizes other species in chemical reaction. Reducing agent is substance that loses its electrons in reaction. Thus, reduces others and oxidizes it.
