Answer: c. oxidation - gain of electrons
Explanation:
1. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.
Example: [tex]Li_2O+CO_2\rightarrow Li_2CO_3[/tex]
2. Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.
Example: [tex]Li_2CO_3\rightarrow Li_2O+CO_2[/tex]
3. Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.
[tex]M\rightarrow M^{n+}+ne^-[/tex]
4. Dehydration reaction is defined as the reaction in which water is lost as product.
[tex]CH_3CH_2OH\rightarrow CH_2=CH_2+H_2O[/tex]
5. Hydrolysis reaction is defined as the reaction in which water is used for decomposition.
Example: [tex]CH_3COOCH_2CH_3+H_2O\rightarrow CH_3COOH+CH_3CH_2OH[/tex]
