Pure substances and mixtures - Free Printable

To solve the problem, we need to classify each substance as a simple substance (element), compound, homogeneous mixture, or heterogeneous mixture. Let's go through each substance step by step:

Definitions:

1. Simple Substance (Element): A substance that consists of only one type of atom.
2. Compound: A substance made up of two or more different types of atoms bonded together in a fixed ratio.
3. Homogeneous Mixture: A mixture that is uniform throughout, with components that are not visibly separate.
4. Heterogeneous Mixture: A mixture that is not uniform throughout, with components that are visibly separate.

Classification of Each Substance:

1. Seawater:
- Classification: Heterogeneous mixture
- Reason: Seawater contains various dissolved salts and other substances, which are not uniformly distributed at the molecular level.

2. Ammonia (NH₃):
- Classification: Compound
- Reason: Ammonia is composed of nitrogen (N) and hydrogen (H) atoms bonded together in a fixed ratio (1:3).

3. Bronze:
- Classification: Homogeneous mixture
- Reason: Bronze is an alloy of copper and tin, which are uniformly mixed on a microscopic level.

4. Sparkling water:
- Classification: Homogeneous mixture
- Reason: Sparkling water is water with dissolved carbon dioxide, which is uniformly distributed.

5. Iron (Fe):
- Classification: Simple substance (element)
- Reason: Iron is composed of only iron atoms.

6. Candy canes:
- Classification: Heterogeneous mixture
- Reason: Candy canes contain sugar, flavoring, and other ingredients that are not uniformly distributed.

7. Vinegar:
- Classification: Homogeneous mixture
- Reason: Vinegar is a solution of acetic acid in water, which is uniformly distributed.

8. Ozone (O₃):
- Classification: Compound
- Reason: Ozone is composed of three oxygen atoms bonded together.

9. Brown sugar:
- Classification: Heterogeneous mixture
- Reason: Brown sugar is a mixture of sucrose (sugar) and molasses, which are not uniformly distributed.

10. Wine:
- Classification: Homogeneous mixture
- Reason: Wine is a solution of ethanol, water, and other compounds, which are uniformly distributed.

11. Water and oil:
- Classification: Heterogeneous mixture
- Reason: Water and oil do not mix and remain separate phases.

12. Potassium chloride (KCl):
- Classification: Compound
- Reason: Potassium chloride is composed of potassium (K) and chlorine (Cl) atoms bonded together in a fixed ratio.

13. Chocolate with almonds:
- Classification: Heterogeneous mixture
- Reason: Chocolate with almonds contains chocolate and almond pieces, which are not uniformly distributed.

14. Carbon dioxide (CO₂):
- Classification: Compound
- Reason: Carbon dioxide is composed of carbon (C) and oxygen (O) atoms bonded together in a fixed ratio.

15. Fruit salad:
- Classification: Heterogeneous mixture
- Reason: Fruit salad contains different types of fruits, which are not uniformly distributed.

16. Cologne:
- Classification: Homogeneous mixture
- Reason: Cologne is a solution of alcohol, fragrances, and water, which are uniformly distributed.

17. Tin (Sn):
- Classification: Simple substance (element)
- Reason: Tin is composed of only tin atoms.

18. Tap water:
- Classification: Homogeneous mixture
- Reason: Tap water contains dissolved minerals and other substances, which are uniformly distributed.

19. Fluorine (F₂):
- Classification: Simple substance (element)
- Reason: Fluorine is composed of only fluorine atoms.

20. Ethanol (C₂H₆O):
- Classification: Compound
- Reason: Ethanol is composed of carbon (C), hydrogen (H), and oxygen (O) atoms bonded together in a fixed ratio.
