Particles in a gas are small, hard spheres with insignificant volume.

True

Gases can be elements in pure form?

True

At low temp, particles of a gas move slowly?

True

If particles are compressed into a smaller space, the pressure is higher?

True

If more particles are added to a container, collisions go up, pressure goes up?

What type of bond/attractive force makes water so unique?

Hydrogen Bonds

Some substances dissolve readily into other substances to form a/an

Solution

Solutions are made up of 2 parts

Solute and solvent

Explain how the 2 parts of a solution are determined (solute, solvent)

• solute is the substance being dissolved

• solvent is the substance doing the dissolving

Explain what an aqueous solution is?

An aqueous solution is a solution where water is the solvent

How are electrolytes and nonelectrolytes different?

• Electrolytes conduct electricity in solution

• Nonelectrolytes do not conduct electricity

What is a hydrate?

A compound that contains water molecules in its crystal structure

What is the process of efflorescence?

When a hydrate loses water to the air

What is the dissolution rate?

The speed at which a solute dissolves in a solvent

Solvation vs.  Saturation

• Solvation: solvent particles surround solute particles

• Saturation: no more solute can dissolve at a given temperature
