reactions

Activation Energy (AE)

The energy added endothermically to the reactant side to ensure effective energy is present to start a reaction.

Effective Collisions

Collisions that lead to a reaction, influenced by factors like temperature, concentration, and gas volume.

Precipitate

A solid that forms as a product in a chemical reaction and falls to the bottom of the solution.

Solubility Rules

Guidelines that determine the solubility of compounds in water based on the ions present.

Exothermic Reaction

A reaction where energy is released, resulting in products with lower energy than the reactants.

Endothermic Reaction

A reaction that absorbs energy, resulting in products with higher energy than the reactants.

Mass Conservation

In a chemical reaction, the number of atoms on the reactant side equals the number of atoms on the product side.

Thermal Energy Flow

The transfer of heat energy, indicated by positive or negative signs in a chemical reaction, affecting surrounding temperatures.

Electrolytes

Ionic compounds that dissolve in water to produce ions capable of conducting electricity.

Balancing Chemical Equations

The process of making sure that the number of each type of atom is equal on both sides of a chemical equation.
