Which of the following might be included in a chemical
reaction?



a Molecules
b lons
C Pure elements
d All of the above

Answer:

D. All of the above

Explanation:

Molecules, ions, and pure elements might be included in a chemical reaction. Therefore, option (d) is correct.

A chemical reaction can be described as a reaction that brings the chemical conversion of one chemical substance to another chemical substance. The reactions cause chemical changes that include the rearrangement of electrons in order to create and break bonds between atoms.

The compound or molecules which are primarily utilized in a reaction are called reactants. Chemical reactions give products, which possess characteristics different from the reactants of the reaction.

Chemical reactions take place at a definite rate of reaction at a given concentration, temperature, and pressure. The rate of reaction increases with the rising temperature of the reaction as more activation energy is available for reactant molcules collisions.

Therefore, in a chemical reaction reactants and products can be present as Molecules, ions, and pure elements.
