Mixtures and Solutions online worksheet - Free Printable

Problem Analysis:

The worksheet is divided into three sections:
1. Section A: Identify whether the given items are Homogeneous or Heterogeneous.
2. Section B: Identify the solute and solvent in each solution.
3. Section C: Use terms from the vocabulary box to fill in the blanks.

Let's solve each section step by step.

Section A: Homogeneous or Heterogeneous

#### Definitions:
- Homogeneous: A mixture where the components are uniformly distributed throughout, and no individual components can be visually distinguished (e.g., saltwater).
- Heterogeneous: A mixture where the components are not uniformly distributed, and different phases or regions can be visually distinguished (e.g., a salad).

#### Images and Identification:
1. Hamburger: Heterogeneous (different layers of ingredients like bread, meat, cheese, etc.)
2. Coffee: Homogeneous (if well-mixed, the coffee and water form a uniform solution)
3. Salad: Heterogeneous (different types of vegetables and dressings are visible)
4. Soda Can: Homogeneous (the contents inside the can are a uniform liquid)
5. Salt Water: Homogeneous (salt is dissolved in water, forming a uniform solution)
6. Cloud: Heterogeneous (clouds consist of water droplets and air, which are visibly distinct)
7. Cereal with Milk: Heterogeneous (cereal pieces are visible in the milk)
8. Bucket with Paint: Heterogeneous (paint has solid particles mixed with liquid)
9. Oil and Water: Heterogeneous (oil and water do not mix and form separate layers)
10. Alcohol Bottle: Homogeneous (alcohol is a uniform liquid)

#### Answers:
1. Heterogeneous
2. Homogeneous
3. Heterogeneous
4. Homogeneous
5. Homogeneous
6. Heterogeneous
7. Heterogeneous
8. Heterogeneous
9. Heterogeneous
10. Homogeneous

Section B: Solvent and Solute Identification

#### Definitions:
- Solute: The substance that is dissolved in the solvent.
- Solvent: The substance that dissolves the solute (usually the larger component).
