Exploring Mixtures in Science

What is a mixture?

• A solution where one substance is dissolved in another

• A physical combination of two or more substances that retain their properties

• A chemical combination of two or more substances

• A single substance with unique properties

Can mixtures be separated easily?

• Not without altering their properties

• Only through chemical reactions

• No, because they are chemically combined

• Yes, because they are physically combined

Why can mixtures be considered special?

• They cannot be separated

• They change the properties of their components

• They are always in a liquid state

• They retain the properties of their components when mixed

What is a heterogeneous mixture?

• A chemical combination of substances

• A mixture where components cannot be distinguished

• A mixture where components can be seen and separated

• A mixture that changes the properties of its components

What is an example of a heterogeneous mixture?

• Peanuts, pretzels, and chocolate chips mixed together

• Saltwater

• Air

• Sugar dissolved in water

What is a homogeneous mixture?

• A mixture where components cannot be seen

• A mixture that cannot be separated

• A mixture with visible components

• A solid mixture only

What is a solution?

• A homogeneous mixture

• A gas mixture

• A solid mixture

• A heterogeneous mixture

Can solutions be in states other than liquid?

• Yes, they can be solid, liquid, or gas

• Only liquid and gas

• No, they are always liquid

• Only solid and liquid

What roles do solute and solvent play in a solution?

• Solute and solvent are not part of a solution

• Solute dissolves, solvent does the dissolving

• Solvent dissolves, solute does the dissolving

• Both solute and solvent dissolve each other

What is the solute in lemonade?

• Water

• Lemon juice

• Sugar

• Ice
