A skeleton equation is not a balanced equation.- Is this sometime true, never true or always true?

Can't there be some skeleton equation that is already balanced, thus it sometime true? Thanks

In chemistry, a skeleton equation represents a chemical reaction without indicating the relative amounts of each reactant and product. It is simply a summary of the reactants and products involved.

It is always true that a skeleton equation is not a balanced equation by default. This is because a balanced equation must have the same number of atoms of each element on both sides of the equation.

However, it is possible for there to be a skeleton equation that is already balanced. This can occur when the reactants and products have equal numbers of atoms of each element present. In such cases, the skeleton equation is already balanced and does not require any further adjustments.

So, while it is usually true that a skeleton equation is not a balanced equation, there can be exceptions where a skeleton equation is already balanced.
