SEMESTER EXAM REVIEW

Front

What is the effect of surface area on the rate of dissolution?

Back

A larger surface area increases the rate of dissolution because more particles are exposed to the solvent.

Front

What is concentration in a solution?

Back

Concentration refers to the amount of solute present in a given volume of solvent.

Front

Which object has the highest temperature?

Back

The Sun has the highest temperature compared to an iceberg, ice cube, and boiling pot of water.

Front

What do the chemical formulas C3H8O, C4H10O, and C5H12O have in common?

Back

These compounds contain the same elements: carbon (C), hydrogen (H), and oxygen (O).

Front

What is inertia?

Back

Inertia is the tendency of an object to remain stationary or to remain in motion unless acted upon by an external force.

Front

What happens to the concentration of a solution when a solute is dissolved in a fixed amount of solvent?

Back

The concentration remains the same if the amount of solute and solvent is constant.

Front

How does temperature affect the solubility of solids in liquids?

Back

Generally, as temperature increases, the solubility of solids in liquids also increases.

Front

What is the relationship between temperature and kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent to form a solution.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, resulting in a solution.
