Define a chemical equation. What is an unbalanced chemical equation called?
(N/A) chemical equation is a symbolic representation of a chemical reaction,where the reactants and products are expressed using their respective chemical symbols and formulae.
An unbalanced chemical equation is known as a skeletal chemical equation.
It provides information about the reactants and products involved in the reaction but does not represent the actual number of atoms of each element on both sides of the equation,thus failing to satisfy the law of conservation of mass.
