An equation in which the relative amounts of reactants and products are not indicated is called a molecular equation.

Here's why:

* Molecular equation: Shows the complete chemical formulas of all reactants and products, but does not indicate their relative amounts. This type of equation focuses on the chemical species involved and their overall transformation.

* Balanced chemical equation: Includes the stoichiometric coefficients that represent the relative amounts of each reactant and product involved in the reaction. This ensures the equation obeys the law of conservation of mass.

Example:

Molecular equation:

HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)

Balanced chemical equation:

HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)

Note: While the molecular equation doesn't show the stoichiometry, the balanced chemical equation does (in this case, a 1:1:1:1 ratio).
