Question

choose the best answers.
8.1) what is chemistry?
a. the study of life
b. the study of matter
c. the study of space
d. the study of energy
8.2) which of these are examples of different types of chemists?
a. environmental chemists, forensic chemists, and pharmaceutical chemists
b. physical chemists, materials scientists, and horticulturists
c. physical chemists, architects, and forensic chemists
d. material scientists, environmental chemists, and veterinarians
8.3) what are three things that chemists do?
□ work with dangerous materials
□ design buildings and bridges
□ conduct experiments to test their ideas
□ analyze evidence to help solve crimes
□ write computer programs

Explanation:

• 8.1: Chemistry is the study of matter. Biology is the study of life (so A is wrong), astronomy is related to the study of space (so C is wrong), and physics also deals with energy concepts but chemistry's main focus is matter.
• 8.2: Environmental chemists, forensic chemists, and pharmaceutical chemists are all types of chemists. Horticulturists (related to plants), architects (design buildings), and veterinarians (animal doctors) are not chemists.
• 8.3: Chemists work with dangerous materials (with proper safety), conduct experiments to test ideas (scientific method), and forensic chemists analyze evidence to help solve crimes. Designing buildings and bridges is for architects/engineers, and writing computer programs is more for computer - related fields.

Answer:

8.1) B. the study of matter
8.2) A. environmental chemists, forensic chemists, and pharmaceutical chemists
8.3) work with dangerous materials, conduct experiments to test their ideas, analyze evidence to help solve crimes
