Homogeneous mixture

The transcript explains the concept of homogeneous mixtures, using examples such as the atmosphere and sugar dissolved in water. It describes how these mixtures appear uniform without visible separation between components.

What is a key characteristic of a homogeneous mixture?

• It can be easily separated by physical means.

• It contains only one type of molecule.

• It is composed of a single uniform medium.

• It has visible layers.

Which of the following is NOT a characteristic of a homogeneous mixture?

• Visible separation of components.

• Components are not easily distinguishable.

• Uniform composition throughout.

• Consistent properties in any sample.

In a homogeneous mixture, how are the components distributed?

• Randomly and unevenly.

• In separate layers.

• Evenly throughout the mixture.

• Only at the surface.

Which of the following best describes the atmosphere?

• A heterogeneous mixture of solids.

• A homogeneous mixture of gases.

• A mixture of liquids.

• A single pure gas.

What happens when sugar is dissolved in water?

• The sugar molecules settle at the bottom.

• The sugar molecules remain separate from the water.

• It forms a heterogeneous mixture.

• It creates a homogeneous mixture.
