Question

Which list includes three types of chemical reactions?

(1) condensation, double replacement, and sublimation
(2) condensation, solidification, and synthesis
(3) decomposition, double replacement, and synthesis
(4) decomposition, solidification, and sublimation

Answer 1

Answer=3

Decomposition, double replacement, and synthesis are 3 types of chemical reactions.

Answer 2

Answer: (3) decomposition, double replacement, and synthesis

Explanation:

Decomposition is a chemical reaction in which one reactant gives two or more than two products.

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

Synthesis reaction is a chemical reaction in which two reactants combine to give a single product.

Solidification, condensation and sublimation are physical changes which only involves phase changes.
