Multiple Choice

As them temperature goes up in a liquid the solubility of a solid generally -?-.

• Increases

• decreases

• stays the same

Fill in the Blanks

Why does breaking up a solute into smaller pieces result in an increase in the rate of dissolving?

Multiple Choice

What do we mean by like dissolves like?

• ionic compounds dissolve only covalent compounds and vice versa

• only compounds with the same EN can dissolve

• polar compounds dissolve polar compounds and nonpolar dissolves nonpolar

• only compounds from opposite sides of the PT dissolve

Multiple Choice

You see black, shiny flakes in a solid mixture. You suspect is it possibly iron filings. What is the best methodto separate the mixture?

• evaporation

• magnetism

• filtering

• distillation

Fill in the Blanks

A particular student tends to have a sweet tooth and he keeps adding sugar to his room temperature tea (I know gross) until no more sugar will dissolve. What type of solution is this?

Fill in the Blanks

A particular student tends to have a sweet tooth and wants to add more sugar than will normally be dissolved at that temperature. What can he do to add more sugar to his tea (again he has issues even Bojo does not meet his high standards for sweetness).
