Question

10 Which terms identify types of chemical reactions?(1) decomposition and :sublimation

Answer 1

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.

$ABC\rightarrow A+B+C$

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).

Answer 2
