the equation is unbalanced becoz the mass is not the same on both sides of equation such a chemical equation is a skeletal chemical equation for a reaction

An unbalanced equation that uses names of the substances instead of chemical formulas is called a word equation. As a rule, metallic elements are named first and non-metallic next. The suffix of the latter is changed into "ide".

If the number of any certain element in the reactants does not equal exactly the number of that same element in the products, the reaction is unbalanced.

An unbalanced equation (skeleton equation) only indicates the nature of the reactants and products but tells nothing of the stoichiometric ratios, i.e. it tells nothing of how much of each species is present, not which reactant might be in excess or limiting, etc.
