100

An atom or group of atoms that has become charged by gaining or losing one or more electrons.

What is an ion?

100

A strong chemical bond that is formed by the attraction between two ions or opposite charges.

What is ionic bonding?

100

A chemical bond between two atoms, in which each atom shares an electron.

What is a covalent bond?

100

A chemical bond where positive metal ions form a lattice structure with freely moving electrons between them.

What is a metallic bond?

100

An interaction between the atoms of two substances where the atoms rearrange to form two new molecules.

What is a chemical reaction?

200

A new substance produced in a chemical reaction.

What is the product?
200

The substance present at the beginning  of a chemical reaction.

What is the reactant?

200

The tendency of a substance to react with other substances.

What is reactivity?

200
A measure of the strength of a solution, i.e., the amount of the solute in the solvent.

What is concentration?

200

The point of which the rate of the forward reaction is equal to the rate of the backward reaction.

What is equilibrium?

300

The minimum amount of energy a reaction needs to start.

What is activation energy?

300

A substance which speeds up a chemical reaction without being changed by the reaction.

What is a catalyst?

300

Occurs when an atom loses electrons in a reaction, or when a substance loses a hydrogen or gains an oxygen atom in a chemical reaction.

What is oxidation?

300

Occurs when an atom gains electrons in a reaction, or when a substance gains a hydrogen or loses an oxygen atom in chemical reactions.

What is reduction?

300

6.02 x 10(23) (This tells us the number of particles per mole)

What is Avogadro's Number?

400

A reaction that primarily involves the transfer of electrons between two substances.

What is redox reaction.
400

In a chemical reaction, the mass of the products is equal to the mass of the reactants.

What is Law of Conservation of Mass.

400

If a change is made to a reaction in equilibrium, the reaction will adjust itself to counter the effects of that change.

What is Le Chatelier's Principle?

400

Explains why a change in the condition under which a reaction occurs can affect the rate of the reaction, in other words, if more ___________  occur, the faster the rate of reaction.

What is collision?

400

Temperature, concentration, and pressure can all affect the _____________________of a reaction.

What is chemical equilibrium?

500

A chemical reaction that takes in heat.

What is an Endothermic Reaction?

500

A chemical reaction that gives off heat.

What is a exothermic reaction?

500

The SI unit for the amount of a substance.

What is a mole?

500

A reaction in which the products can never be turned back into the reactants.

What is irreversible reaction?

500

A reaction in which. under the right conditions, the products can be turned back into the reactants.

What is reversible reaction?
