Mixtures, Solutions & Chemical Changes

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a combination of two or more substances in which the composition is uniform throughout the mixture.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a combination of two or more substances where the composition is not uniform, and different components can be seen.

Why is water known as the universal solvent?

Back

Water is known as the universal solvent because it can dissolve almost all substances on Earth.

Front

What are the two types of mixtures?

Back

The two types of mixtures are homogeneous and heterogeneous.

Front

What is a solution?

Back

A solution is a homogeneous mixture where one substance (the solute) is dissolved in another (the solvent).

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, resulting in a temperature drop.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases heat to its surroundings, resulting in a temperature increase.

Front

What is solvation?

Back

Solvation is the process of surrounding solute particles with solvent molecules to form a solution.

Front

What is the difference between solute and solvent?

Back

The solute is the substance that is dissolved in a solution, while the solvent is the substance that dissolves the solute.

Front

What is the role of a solvent in a solution?

Back

The solvent is the component of a solution that dissolves the solute and determines the solution's phase.
