Balancing Chemical Equations

A balanced chemical equation has the same number of each type of atom on both sides of the equation, indicating that mass is conserved during the reaction.

Reactants are the substances that undergo a chemical change in a reaction, found on the left side of the equation.

Products are the substances formed as a result of a chemical reaction, found on the right side of the equation.

The purpose of balancing a chemical equation is to ensure that the law of conservation of mass is obeyed, meaning the number of atoms of each element is the same on both sides.

An unbalanced chemical equation indicates that the number of atoms of one or more elements is not the same on both sides, which violates the law of conservation of mass.

To determine if a chemical equation is balanced, count the number of atoms of each element on both sides of the equation and compare them.

Coefficients are numbers placed before compounds in a chemical equation to indicate the number of molecules or moles of that substance involved in the reaction.

The first step in balancing a chemical equation is to write down the unbalanced equation and count the number of atoms of each element on both sides.

A common method for balancing chemical equations is the 'trial and error' method, where coefficients are adjusted systematically until the equation is balanced.

The law of conservation of mass states that mass cannot be created or destroyed in a chemical reaction, meaning the total mass of reactants must equal the total mass of products.
