(a) matter.

(b) transformations of matter.

(c) the submicroscopic realm.

(d) All of the above.

To determine

The correct option for the statement “Chemistry is the study of”.

Answer to Problem 1RAT

The correct option for the statement “Chemistry is the study of ” is option (d).

Explanation of Solution

Chemistry is a branch of science that studies the matter and different transformations matter can undergo.

The matter is made up of atoms. The atoms are the smallest particles of matter. The matter consists of protons, neutrons, and electrons.

The transformations of matter can be of two types. The types are physical change and chemical change. The chemical changes occur at the molecular level and the electrons are involved too.

The sub-microscopic particles are those which cannot be seen with a light microscope. The atoms cannot be seen with a light microscope. So, they come under the sub-microscopic realm.

So, chemistry is a study of matter, transformations of matter, and the sub-microscopic realm.

Conclusion:

Therefore, the correct option is option (d).
