Homogeneous & Heterogeneous Mixtures

What is a heterogeneous mixture?

• A mixture that consists of visibly different substances or phases, which are not evenly distributed.

• A mixture that has a uniform composition throughout.

• A mixture that can be separated by physical means into its components.

• A mixture that contains only one type of substance.

What is an example of a heterogeneous mixture in everyday life?

• A bowl of fruit salad, where different fruits are visible and separable.

• Saltwater, where salt is dissolved in water.

• Air, which is a uniform mixture of gases.

• Vinegar, which is a solution of acetic acid in water.

What is the main difference between homogeneous and heterogeneous mixtures?

• Homogeneous mixtures have a uniform composition, while heterogeneous mixtures do not.

• Heterogeneous mixtures have a uniform composition, while homogeneous mixtures do not.

• Homogeneous mixtures are always solid, while heterogeneous mixtures can be liquid or gas.

• Heterogeneous mixtures are always more stable than homogeneous mixtures.

What is an example of a homogeneous mixture in everyday life?

• Vinegar, which is a uniform solution of acetic acid in water.

• Salad dressing, which separates into layers.

• Sand and salt mixed together.

• Fruit juice with pulp.

What is the definition of solvent?

• The substance that dissolves the solute in a solution.

• A mixture of two or more substances.

• A solid that does not dissolve in any liquid.

• A chemical reaction that produces a gas.

Give an example of a homogeneous mixture.

• Saltwater, where salt is completely dissolved in water.

• Sand and salt mixed together.

• Oil and vinegar salad dressing.

• Cereal in milk.

Why is a bowl of cereal with milk considered a heterogeneous mixture?

• Because the cereal and milk are evenly mixed together.

• Because the cereal and milk are not evenly distributed and can be separated.

• Because the cereal dissolves completely in the milk.

• Because the milk is a solid and the cereal is a liquid.

Can a mixture be both homogeneous and heterogeneous?

• Yes, a mixture can be both homogeneous and heterogeneous.

• No, a mixture is classified as either homogeneous or heterogeneous based on its composition.

• A mixture can only be homogeneous.

• A mixture can only be heterogeneous.

Give an example of a heterogeneous mixture.

• A salad, where the ingredients are distinct and can be separated.

• Saltwater, which is a uniform solution.

• Air, which is a pure substance.

• Sugar dissolved in water, which forms a homogeneous mixture.

What is a homogeneous mixture?

• A mixture that has a uniform composition throughout, meaning the substances are evenly distributed.

• A mixture where the components are visibly distinct and can be separated easily.

• A mixture that contains only one type of substance.

• A mixture that changes composition when stirred or shaken.
