What is Activation Energy?
A chemical reaction in which one element takes the place of another element in a compound
What is a single replacement reaction?
A chemical reaction in which two or more substances react to form a single compound
What is a Synthesis Reaction?
A covalently bonded group of atoms that has a positive or negative charge and acts as a unit
What are Polyatomic ions?

What is a catalyst?
The process that occurs when electricity passes through water and the energy provided by the electricity causes the water to decompose into hydrogen gas and oxygen gas
What is Water electrolysis?
Breaks down into two or more simpler substances
What is Decomposition Reaction?
A chemical reaction in which a substance reacts rapidly with oxygen, often producing heat and light.
What is a Combustion Reaction?
Energy cannot be created or destroyed; it can only be transformed from one type to another.
What is the Law of Conservation of Energy?
A chemical reaction in which two compous exchange positive ions and from new compounds
What is a Double Replacement Reaction?
A chemical reaction that absorbs energy from its surroundings
What is an Endothermic Reaction?
Compounds made of only two elements
What are Binary Compounds?
The ratio of the total distance traveled to the total time of the trip
What is the Average Speed?
A point at which direction is measured
What is a Reference Point?
The distance an object travels plus the direction from the starting point
What is Displacement?
A general process in which molecules (or ionic compounds such as salts, or complexes) separate or splt into smaller particles such as atoms, ions, radicals, usually in a reversible manner
What is Dissociation?
The branch of physics that deals with analyzing and understanding objects in motion, the forces applied to those objects, and the energy that exists in them.
What is Mechanics?
The rate at which an object is moving at a given moment in time.
What is Instantaneous Speed?
A physical measurement that contains only magnitude (number) and does not contain directional information
What is Scalar Quantity?
A physical measurement that contains both magnitude (number) and directional information
What is Vector Quantity?
Refers to using a reference point to detect motion
What is a Frame of Reference?
The time rate of change of an object's velocity
What is Acceleration?
