Question

identify each of the following as an element, a compound, or a mixture:

Explanation:

Step1: Recall definitions

An element has only one - type of atom, a compound has different types of atoms chemically bonded, and a mixture has different substances physically combined.

Step2: Analyze (a)

The image in (a) shows a structure with two different types of atoms chemically bonded together, so it is a compound.

Step3: Analyze (b)

The image in (b) shows identical units, which represent identical molecules. Since all the molecules are the same and composed of multiple atoms bonded together, it is a compound.

Step4: Analyze (c)

The image in (c) shows different - colored and - shaped particles (representing different substances) mixed together in a liquid. These substances are not chemically bonded, so it is a mixture.

Answer:

(a) Compound
(b) Compound
(c) Mixture
