What defines a heterogeneous mixture?

• A mixture where components consist of visibly different components.

• A mixture where components are evenly distributed throughout.

• A mixture where components can be separated by filtration.

• A mixture where components can settle into layers.

What is an example of a mixture that is uniform in nature?

• saline solution

• gravel and sand

• sticks and stone

• rice husk and stones

Which of the following is an example of homogenous mixture?

• air

• granite

• oil and water

• sand and water

Why is oil and water considered a heterogenous mixture?

• It contains only one type of liquid.

• It can settle into two layers over time.

• It can be separated into different types of gas.

• Its components are evenly distributed throughout.

Which of the following best describes the appearance of a heterogeneous mixture?

• A mixture where components are uniform throughout.

• A mixture where components can form a clear solution.

• A mixture where components consist of visibly different substances.

• A mixture where components can easily separate into distinct layers.

Why is vegetable soup a heterogeneous mixture?

• Vegetable soup contains only liquid parts.

• The broth consists of uniformly mixed liquids.

• Vegetable soup components cannot easily be seen and separated.

• It contains different types of vegetables and other soup components; thus, it is easy to separate.

• Sand dissolves completely in water.

• Water evaporates when heated with sand.

• Sand and water mix evenly throughout the mixture.

• Sand settle at the bottom of the container after a few minutes.

Which of the following best describes a solution?

• A mixture of components that can easily be seen.

• A mixture of substances that can be separated physically.

• A homogenous mixture where the solute is dissolved in a solvent.

• A mixture with two or more components of different sizes and shapes.

Which of these is an example of a solution commonly found at home?
