Understanding Chemistry Basics

What is the definition of chemistry?

• Chemistry is the study of living organisms.

• Chemistry is the exploration of celestial bodies.

• Chemistry is the analysis of historical events.

• Chemistry is the study of matter and the changes it undergoes.

Why is chemistry often called the central science?

• Chemistry is unrelated to physics and biology.

• Chemistry is called the central science because it connects and overlaps with other natural sciences.

• Chemistry is only concerned with chemical reactions.

• Chemistry is the study of living organisms.

What are the main branches of chemistry?

• Biochemistry, environmental chemistry, and theoretical chemistry

• The main branches of chemistry are organic chemistry, inorganic chemistry, physical chemistry, and analytical chemistry.

• Astrochemistry, geochemistry, and quantum chemistry

• Materials science, pharmacology, and food chemistry

How does chemistry relate to other sciences?

• Chemistry connects and overlaps with biology, physics, environmental science, and materials science.

• Chemistry is solely about chemical reactions without any connections to other fields.

• Chemistry is unrelated to any other science.

• Chemistry only focuses on the study of atoms.

Can you give an example of a chemical reaction?
