Chemical Processes

The Law of Conservation of Matter states that in a chemical reaction, matter is neither created nor destroyed; the total number of atoms remains the same before and after the reaction.

An Exothermic Reaction is a chemical reaction that releases thermal energy (heat) to its surroundings.

A Reactant is a substance that undergoes a chemical change in a reaction, found on the left side of a chemical equation.

A Product is a substance that is formed as a result of a chemical reaction, found on the right side of a chemical equation.

An Endothermic Reaction is a chemical reaction that absorbs thermal energy (heat) from its surroundings.

A Chemical Reaction is a process in which substances (reactants) are transformed into different substances (products) through the breaking and forming of chemical bonds.

A Precipitate is a solid that forms and settles out of a liquid mixture during a chemical reaction.

A Chemical Formula is a way of expressing the composition of a substance using symbols for its constituent elements and numbers to indicate the ratio of atoms.

Reactants are the starting materials in a chemical reaction, while Products are the substances formed as a result of the reaction.

A balanced reaction has the same number of each type of atom on both sides of the equation, adhering to the Law of Conservation of Matter.
