What is chemical energy?
100
States that mass cannot be created nor destroyed.
What is the Law of Conservation of Mass?
100
AB → A + B
What is a decomposition reaction?
100
A substance that causes a reaction to speed up by lowering the activation energy.
What is a catalyst?
100
The base unit of energy.
What is a Joule?
200
The energy needed to get a reaction started.
What is the activation energy?
200
Meaning dissolved in water.
What is an aqueous solution?
200
A + BC → AC + B
What is a single replacement reaction?
200
Breaking a reactant into smaller pieces increases this, which speeds up the reaction.
What is surface area?
200
Two atoms of the same element that form a bond to make a molecule.
What is diatomic?
300
States that the total energy before the reaction is equal to the total energy present after the reaction.
What is the Law of Conservation of Energy?
300
The numbers placed in front of compounds to balance chemical equations.
What are coefficients?
300
A + B → AB
What is a synthesis or combination reaction?
300
A substance that slows down or stops a reaction.
What is an inhibitor?
300
The amount of copper (II) oxide produced if 100 g of copper fully reacts with 25 g of oxygen gas?
What is 125 g?
400
Heat is released during this kind of reaction.
What is an exothermic reaction?
400
When balancing equations, these are NEVER changed to balance the reaction.
What are subscripts?
400
AD + BC → AC + BD
What is a double replacement reaction?
400
Increasing this will decrease the volume in which reactants interact, which will speed up a reaction.
What is pressure?
400
A biological catalyst.
What is an enzyme?
500
A reaction in which heat is absorbed.

500
The reaction 2Na(s) + Cl2(g) --> 2NaCl(s)
What is solid sodium combines with chlorine gas to produce sodium chloride?
500
A reaction in which a compound and oxygen burn.
What is a combustion reaction?
500
An enzyme found in organisms, such as carrots, that decompose peroxide into water.
