solubility and gases

Colloids have particles that settle at the bottom.

• true

• false

Suspension mixtures are homogeneous mixtures

• true

• false

A type of mixture where the particles are larger than those in a solution but not heavy enough to settle out.

• Homogeneous mixture

• Suspension

• Compound

• Colloid

A solution with less than the maximum amount of solute completely dissolved.

• Unsaturated solution

• Supersaturated solution

• Saturated solution

An ionic compound has a solubility of 30 g per 100 mL of water at room temperature. A solution containing 50 g of the compound in 100ml  of water at high temperature is:

• supersaturated

•    suspension

• unsaturated

An ionic compound has a solubility of 30 g per 100 mL of water at room temperature. A solution containing 17 g of the compound in 100 mL of water at the same temperature is:

• saturated  

• unsaturated

• supersaturated      

How does this factor affect the solubility of a GAS? Increasing temperature

• More soluble

• No effect

• Less soluble

Which of the following is a characteristic of a colloid?

• Particles settle out over time

• Particles can be filtered out

• Exhibits Tyndall effect

Which is an example of homogenous mixture?

• NaCl dissolves in water

• Milk

• Fog

When the air temperature increases,

• the particles move faster, the pressure increases

• the particles move slower, the pressure increases

• the particles move slower, the pressure decreases
