1.2 Mixtures

• What is the composition of a homogeneous mixture?

  Uniform throughout
• A homogeneous mixture has a uniform composition throughout.
• Match the type of mixture with its example:

  Homogeneous ↔️ Sugar dissolved in water

  Heterogeneous ↔️ Salad
• What is one physical property that can vary in mixtures?

  Density
• What are examples of homogeneous mixtures?

  Sugar dissolved in water, air
• What are examples of heterogeneous mixtures?

  Salad, muddy water
• What is a mixture defined as in chemistry?

  Two or more non-combined substances
• Mixtures can be classified as either homogeneous or heterogeneous.
• What is the composition of a heterogeneous mixture?

  Non-uniform
• A heterogeneous mixture has a non-uniform composition where the different components are visibly distinct.
• Mixtures can be separated using physical methods.
• Match the mixture property with its description:

  Physical Properties ↔️ Density, boiling point can vary

  Chemical Properties ↔️ Components retain original behavior

  Separation ↔️ By physical means
• The chemical properties of components in a mixture are retained.
• What are three physical separation techniques for mixtures?

  Filtration, distillation, chromatography
