Question

What can form as a result of a chemical reaction?

Answer 1

Answer:

Compounds

Explanation:

Chemical reactions involving more than one element mostly give rise to compounds when transfer of electrons occurs.

The compounds are as a result of the combination of the individual elements and radicals.

Isotopes occur naturally while alpha (α) and beta (β) particles are as a result of nuclear reactions.

Answer 2

Answer: compounds

Explanation:

A physical reaction is defined as the reaction in which a change in shape, size takes place. No new substance gets formed in these reactions.

A chemical reaction is defined as the reaction in which a change in chemical composition takes place. A new substance or compound is formed in these reactions.

$2H_2+O_2\rightarrow 2H_2O$

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. It can be decomposed into simpler constituents using chemical reactions. Example: water $H_2O$

Isotopes, alpha and beta particles are formed in nuclear reactions.
