Pure substances that cannot be further broken down into simpler substances by ordinary chemical reactions.
What are elements?
200
A state of matter where particles move the fastest
What is a gas
200
Alteration of a substance in its phase of matter and appearance without its being changed into a new substance.

When balancing chemical equations, you can only add this to the equation
What are coefficients
400
Matter can neither be created or destroyed, only altered to a different form.
What is the conservation of matter
500
Negatively charged particles that move constantly in levels, or shells, around the nucleus.

A substance going from a gas to a liquid
What is condensation
500
Wood burning is an example of this
What is a chemical change
500
This CAN NOT be changed when balancing equations
What are subscripts
500
An equation can only be balances if all molecules have coefficients
What is false
