A skeletal chemical equation is a basic representation of a chemical reaction that shows the chemical formulas of the reactants and products, but does not balance the number of atoms of each element on both sides.

Here's a breakdown:

* Chemical reaction: A process involving the rearrangement of atoms and molecules, resulting in the formation of new substances.

* Reactants: The substances that undergo a chemical change.

* Products: The substances that are formed as a result of the chemical reaction.

* Balancing: Ensuring that the number of atoms of each element is the same on both the reactant and product sides of the equation.

Example:

Skeletal chemical equation:

* Fe + O₂ → Fe₂O₃

This equation shows iron (Fe) reacting with oxygen gas (O₂) to form iron oxide (Fe₂O₃). However, it is not balanced because there are 2 oxygen atoms on the reactant side and 3 oxygen atoms on the product side.

Balanced chemical equation:

* 4Fe + 3O₂ → 2Fe₂O₃

This equation is balanced because there are 4 iron atoms and 6 oxygen atoms on both sides of the equation.

In summary:

A skeletal chemical equation is a simple representation of a reaction before it is balanced. It is a starting point for understanding the chemical change taking place and for subsequently balancing the equation to accurately represent the stoichiometry of the reaction.
