In a chemical equation, the products are found on the right side. This is a standard convention in chemistry. When a chemical reaction occurs, reactants (the starting substances) are transformed into products (the substances formed as a result of the reaction).
For example, in the equation:
2H2 + O2 → 2H2O
the reactants are hydrogen (H2) and oxygen (O2), which are located on the left, while the product, water (H2O), is on the right. This layout helps to clearly illustrate the transformation taking place during the reaction.
