Answer

Explanation:

Step1: Recall compound definition

A compound is a substance made up of two or more different - element atoms chemically bonded together.

Step2: Analyze diagrams

In diagram A, there are only single - type atoms, so it is an element. In diagram B, there are molecules made up of two different types of atoms bonded together, which is a compound. In diagram C, there are different types of molecules not chemically bonded to each other, which is a mixture.

Step3: Answer question 21

Since diagram B shows a compound, the answer to question 21 is b.

Step4: Answer question 22

Since diagram C shows a mixture, the answer to question 22 is c.

Answer:

  1. b. diagram B
  2. c. diagram C
