Explanation:

Step1: Recall definitions

Elements are made of one - type of atom. Compounds have more than one type of atom chemically bonded. Mixtures are substances not chemically combined and can be separated by physical means.

Step2: Answer question 1

Molecules with more than one type of atom chemically bonded are compounds. So the answer is red.

Step3: Answer question 2

A substance made of only one type of atom is an element. So the answer is sky - blue.

Step4: Answer question 3

Two or more substances not chemically combined are mixtures. So the answer is purple.

Step5: Answer question 4

The elements within a mixture can be separated by physical means. So the answer is blue.

Step6: Answer question 5

The elements within a compound can only be separated by a chemical change. So the answer is red.

Step7: Answer question 6

Ice - cream is a mixture. So the answer is yellow.

Step8: Answer question 7

A platinum ring is an element. So the answer is yellow - green.

Step9: Answer question 8

The ocean is a mixture. So the answer is red - orange.

Step10: Answer question 9

Pure water is a compound. So the answer is orange.

Step11: Answer question 10

A diamond is an element. So the answer is sky - blue.

Step12: Answer question 11

The air we breathe is a mixture. So the answer is yellow - orange.

Step13: Answer question 12

Ammonia ($NH_3$) is a compound. So the answer is yellow.

Step14: Answer question 13

The diagram shows a mixture of different particles. So the answer is light red.

Step15: Answer question 14

The diagram shows an element (same type of atoms). So the answer is red.

Step16: Answer question 15

The diagram shows a compound (same type of molecules with different atoms). So the answer is sky - blue.

Answer:

1. Compound (red)
2. Element (sky - blue)
3. Mixture (purple)
4. Mixture (blue)
5. Compound (red)
6. Mixture (yellow)
7. Element (yellow - green)
8. Mixture (red - orange)
9. Compound (orange)
10. Element (sky - blue)
11. Mixture (yellow - orange)
12. Compound (yellow)
13. Mixture (light red)
14. Element (red)
15. Compound (sky - blue)
