Which of the following is a redox reaction but not a combination reaction?
Answer:
In chemistry, redox reactions involve the transfer of electrons between reactants. These reactions can be of different types, such as combination, decomposition, displacement, or disproportionation reactions. To identify a redox reaction that is not a combination reaction, we need to understand the characteristics of both types.
A combination reaction is when two or more substances combine to form a single compound as a product. On the other hand, a redox reaction involves the transfer of electrons between reactants. Combustion reactions, single replacement reactions, and disproportionation reactions are examples of redox reactions.
Therefore, the redox reaction that is not a combination reaction could be a single replacement reaction or a disproportionation reaction. In a single replacement reaction, an element replaces another element in a compound, while in a disproportionation reaction, the same element is both oxidized and reduced within a single reactant. Both of these reactions involve electron transfer without simply combining elements into a single compound.
