# Balance the equation: {eq}\displaystyle \rm 4Al (s) +3O_2 (g) \to 2Al_2O_3(s) {/eq}

## Question:

Balance the equation:

{eq}\displaystyle \rm 4Al (s) +3O_2 (g) \to 2Al_2O_3(s) {/eq}

## Balancing Chemical Equations:

A chemical equation reflects the formation of products from a given set of reactants. The number of atoms of each element remains unchanged. A chemical change does not involve the transformation of elements into new elements. We balance a chemical equation to represent that the number of atoms of each element remains unchanged.
