What is a homogeneous mixture?
A homogeneous mixture is a mixture that can be easily separated.
A homogeneous mixture is a mixture that has varying composition throughout.
A homogeneous mixture is a mixture with distinct layers.
A homogeneous mixture is a mixture with a uniform composition throughout.
Give an example of a homogeneous mixture.
Oil

What is a heterogeneous mixture?
A homogeneous mixture is a mixture where the components are uniformly distributed.
A heterogeneous mixture is a pure substance with a fixed composition.
A heterogeneous mixture is a mixture where the components are not uniformly distributed and can be easily distinguished.
A heterogeneous mixture cannot be separated into its components.
Give an example of a heterogeneous mixture.
Fruit smoothie
Salad
Air

What is a solution in the context of mixtures?
A solution is a mixture that cannot be separated by physical means.
A solution is a homogeneous mixture of a solute dissolved in a solvent.
A solution is a type of chemical reaction.
A solution is a solid mixture of different particles.
What is a colloid?
A colloid is a gas that has no particles in it.
A colloid is a pure substance with uniform composition.
A colloid is a type of solid material.
A colloid is a mixture with tiny particles dispersed throughout another substance.
What is a suspension?
A suspension is a mixture where solid particles are dispersed in a liquid or gas.
A suspension is a gas that contains only vapor particles.
A suspension is a solution where all components are completely mixed.
A suspension is a type of solid that cannot dissolve in any liquid.
Name a common separation technique for mixtures.
Filtration
Chromatography
Distillation
Centrifugation
What is filtration used for?
Filtration is used for heating substances.
Filtration is used for mixing liquids together.
Filtration is used for separating solids from liquids or gases.
Filtration is used for creating solid materials.
What is distillation?
A method to combine liquids into a single solution.
A process used to cool down liquids quickly.
A technique for mixing solid substances together.
Distillation is a method used to separate mixtures based on differences in boiling points.
How does chromatography work?
Chromatography uses heat to separate components based on their boiling points.
Chromatography separates mixtures by using a stationary phase and a mobile phase to exploit differences in component interactions.
Chromatography relies solely on electrical charges to separate mixtures.
Chromatography combines all components into a single phase for analysis.
What is the difference between a mixture and a compound?
A mixture retains the properties of its components, while a compound has a fixed composition and distinct properties.
A mixture has a fixed composition, while a compound retains the properties of its components.
A mixture is always a solid, while a compound is always a liquid.
A mixture can only be formed by combining two gases, while a compound can be formed from any state of matter.

They have a uniform composition.
List one property of heterogeneous mixtures.
Components are not uniformly distributed.
The mixture has a consistent texture throughout.
All components are visible to the naked eye.
Components are uniformly distributed.
