gregori [183]

Answer : The correct option is, (a) Synthesis

Explanation :

Synthesis reaction : A chemical reaction where multiple substances or reactants combine to form a single product.

It is represented as,

X+Y\rightarrow XY

Combustion reaction : A chemical reaction in which a hydrocarbon react with the oxygen to give product as carbon dioxide and water.

It is represented as,

CH_4+2O_2\rightarrow CO_2+2H_2O

Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.

It is represented as,

A+BC\rightarrow AC+B

In this reaction, A is more reactive element and B is less reactive element.

Double replacement reaction : It is a type of chemical reaction where a positive cation and a negative anion of two reactants exchange places to form two new products.

It is represented as,

XY+AB\rightarrow XB+AY

(X and A are the cations, Y and B are the anions)

The given reaction is, Ca+Cl_2\rightarrow CaCl_2

In this reaction, calcium combine with the chloride to form calcium chloride as a product.

Hence, the given type of reaction is a synthesis reaction.
