Question

1. classify each example below as the type of matter it is (element, compound, or mixture) a. b. c.

Explanation:

Step1: Recall definitions

An element consists of only one - type of atom, a compound consists of two or more different types of atoms chemically bonded, and a mixture contains two or more different substances not chemically combined.

Step2: Analyze part a

There are single atoms and di - atomic molecules. Since there are different types of particles (single atoms and molecules), it is a mixture.

Step3: Analyze part b

All the particles are the same type of di - atomic molecules. Since all particles are identical and composed of two atoms chemically bonded, it is a compound.

Step4: Analyze part c

All the particles are the same type of tri - atomic molecules. Since all particles are identical and composed of three atoms chemically bonded, it is a compound.

Answer:

a. Mixture
b. Compound
c. Compound
