Atoms

100

A pure substance made up of only one type of atom is a/an

element

200

A pure substance made from more than one type of atom is called a/an

compound

300

What are the 3 subatomic particles?

Protons, neutrons and electrons

400

A combination of elements, compounds or both, that is not pure, is called a/an:

mixture

500

Water, or Hydrogen atoms bonded with Oxygen atoms is called a/an:

compound

Matter Properties

100

pH stands for: 

Potential for Hydrogen Ions

200

The process of adding carbon dioxide to a liquid is called:

carbonation

300

Acid or Base? A substance that produces Hydrogen ions when it is added to water is a/an:

Acid

400

Acid or Base? A substance that accepts Hydrogen ions when it is added to water is a/an:

Base

500

When a molecule of acid is put into water and it breaks apart, it:

dissocoiates

Solid, Liquid, Gas

100

When the particles are packed tightly together and atoms have very little vibration, but are fixed in position, it is called a:

solid

200

When the particles are able to flow around each other, with an indefinite shape making it hard to compress, but have a fixed volume

Liquid

300

This has a high kinetic energy, no definite shape or volume, and cannot be squashed

A Gas

400

Adding or removing energy from matter causes a: 

physical change of state

500

When a solid changes to a gas (without becoming a liquid), it's called:

sublimation

States of Matter

100

The energy of moving matter particles is called what type of energy?

Kinetic energy

200

Non-polar molecules repel water and are called:

Hydrophobic

300

When solvents move from a region of lower solute concentration to higher solute concentration, it's called:

osmosis

400

The type of reaction process that releases heat, causing the temperature of the surroundings to rise is called: 

exothermic reactions

500

The type of reaction process where heat is absorbed and cools the surroundings is called: 

endothermic reactions

Emulsification

100

True or False: The solvent is the liquid, and the solute is the minor component dissolved to make a solution

True

200

Polar molecules that are attracted to water are called:

Hyrdophilic

300

When a protein that looks like a ball of yarn is mechanically unravelled through whisking is the process called: 

denaturation

400

Ice absorbs energy as it melts, but _____ water does not release energy by freezing and therefore lowers the freezing point of water.

Salt

500

A molecule that contains both a hydrophobic and a hydrophilic region to help attract polar and non-polar molecules together is called an:

emulsifier
