What is a chemical change
The speed of a reaction is called this:
What is the reaction rate
The energy needed for a chemical reaction to occur is called this:
What is activation energy
The mass of one mole of a substance is called this:
What is molar mass
Two or more reactants that combine into a single, more complex product are called this:
What is a synthesis reaction
The substances that enters into a chemical equation are called this:
What are reactants
The substances that reactants combine to produce are called this:
What are products
A substance that helps a reaction happen faster, but is not used up in the reaction is called this:
What is a catalyst
This is what we call a substance that slows the rate of reaction by reducing the effectiveness of catalysts:
What is an inhibitor
A single reaction that breaks down into two or more products is called this:
What is a decomposition reaction
This is what we call a number placed in front of a formula within a chemical equation to balance it:
What is a coefficient
This is what we call a loss of electrons in a chemical reaction:
What is oxidation
A chemical reaction that releases more energy than it absorbs is called this:
What is an exothermic reaction
This represents a state in which multiple influences cancel each other out:
What is equilibrium
When one element in a compound is replaced by another element it is called this type of reaction:
What is a single-replacement reaction
This is the law that states that energy cannot be created or destroyed:
What is the Law of Conservation of Energy
This is what we call a gain of electrons in a chemical reaction:
What is reduction
A chemical reaction that absorbs more energy that it releases is called this:
What is an endothermic reaction
This is the principle that states that a chemical system in equilibrium will adjust its equilibrium position in such a way as to reduce the effect of any changes made to the system:
What is La Chatlier's Principle
When two compounds swap cations or anions with each other it is called this type of reaction:
What is a double-replacement reaction
List the 8 evidences for chemical change: (hit C BOB PET C)

List the 5 factors that affect reaction rates: (hint: SSTCC)
What are surface area, stirring, temperature, concentration, and catalysts
Describe the 3 key points of the Collision Model
What is that for a reaction to occur, the particles must COLLIDE with each other, with the proper ALIGNMENT, and with ENOUGH ENERGY.
