Question

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 1

#2. Decomposition and synthesis

Answer 2

Answer:The correct option is option(2).

Step-by-step explanation:

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

`ABC\rightarrow A+B+C`

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

`A+B+2C\rightarrow ABC_2`

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).
