Mixtures (Right)1) What is a

mixture?

2) What are the two different types of mixtures?

3) What is a solution?

1) Mixture: two or more elements in which a physical change takes place. (Chem change = compound)

2) Homogenous: the same uniform appearance and composition throughout (solutions)

Heterogeneous visibly different substances or phases. (suspension)

3) Solution a homogeneous mixture of two or more substances. A solute is dissolved in a solvent in a physical change. These substances do not undergo a chemical change, and they can be separated again.

Types of mixtures

• Mixture

• Heterogeneous

• Homogeneous

• Solution

• Suspension
