Meaning

A Balanced Symbol Equation is a way to show the reactants and products in a chemical reaction using the chemical formulae of the reactants and products.

About Balanced Symbol Equations

Balanced Symbol Equations shows the number of molecules of each chemical and the numbers of each atom within those chemicals.

Balanced Symbol Equations can be used to find the quantity of each chemical needed to have a complete chemical reaction.

The Word Equation has been given above each Balanced Symbol Equation.

This shows there are two H₂ molecules and one O₂ molecule needed to make two molecules of H₂O.

This shows there is one CH₄ molecule and two O₂ molecules needed to make one molecule of CO₂ and two molecules of H₂O.

This shows there are two atoms of Mg and one molecule of O₂ needed to make two molecules of MgO.

This shows there are two HCl molecules and one Li₂O molecule needed to make two molecules of LiCl and one molecule of H₂O.
