Which of the following pairs is mismatched? select one: a. synthesis reaction - two reactants combine to form a larger product b. decomposition reaction - large reactant broken into smaller products c. oxidation - gain of electrons d. dehydration reaction - water is a product of the reaction e. hydrolysis - water is used in decomposition reaction

c. oxidation - gain of electrons

Explanation:

1. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.

Example:  

2. Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

Example:

3. Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

4. Dehydration reaction is defined as the reaction in which water is lost as product.

5. Hydrolysis  reaction is defined as the reaction in which water is used for decomposition.

Example:

c. 4.54 x 10–12 j happens to be correct
