Chemical reactions involve the transformation of one or more substances into different substances with new chemical properties. They typically involve the breaking and forming of chemical bonds. Chemical reactions are represented using chemical equations, where reactants on the left side of the equation react to form products on the right side.

For example, the chemical equation for the reaction between hydrogen gas (H2) and oxygen gas (O2) to form water (H2O) is:

2H2 + O2 → 2H2O

In this reaction, two molecules of hydrogen gas (H2) react with one
