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



Answer :

#2. Decomposition and synthesis

Answer: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.

[tex]ABC\rightarrow A+B+C[/tex]

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

[tex]A+B+2C\rightarrow ABC_2[/tex]

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).
