10 which terms identify types of chemical reactions? (1) decomposition and : sublimation
(2) decomposition and synthesis
(3) deposition and sublimation
(4) deposition and synthesis

The correct option is option(2).

Explanation:

Decomposition : It is a type of a chemical reaction in which reactant breaks down into its constituent elements.

Synthesis : It is a type of chemical reaction in which two or more than two reactants combines together to form a single product.

Where as sublimation and deposition are process related to the change in state of the matter.

Sublimation: Conversion of substance from solid state to gaseous state directly.

Deposition:Conversion of substance from gaseous state to solid state directly.

Hence, the correct answer is option (2).

the answer is d.) potassium
