What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture that has a uniform composition throughout. Examples include coffee and hydrogen peroxide.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture that does not have a uniform composition. An example is trail mix.

Front

What is the effect of stirring on the dissolving process?

Back

Stirring increases the rate of dissolving by distributing the solute particles throughout the solvent.

Front

How does temperature affect the rate of dissolving?

Back

Increasing the temperature generally increases the rate of dissolving because it gives particles more energy to interact.

Front

What is surface area in the context of dissolving?

Back

Surface area refers to the exposed area of a solid solute. A larger surface area allows for faster dissolving.

Front

What is a compound?

Back

A compound is a substance formed when two or more elements are chemically bonded together. An example is carbon dioxide.

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that are not chemically combined.

Front

What is the difference between a solute and a solvent?

Back

A solute is the substance that is dissolved, while a solvent is the substance that does the dissolving.

Front

What happens when you add larger pieces of sugar to a solution?

Back

Adding larger pieces of sugar slows down the dissolving process because they have less surface area exposed to the solvent.

Front

What is the role of color in the rate of dissolving?

Back

Color does not affect the rate of dissolving; factors like temperature, stirring, and surface area do.
