If the number of atoms of any one element is not the same on the reactant and product sides of a chemical equation, what is the equation called?
Answer and explanation
Correct answer: Unbalanced chemical equation
In a balanced chemical equation, the number of atoms of each element is the same on the reactant and product sides, satisfying the law of conservation of mass. If the atoms of even one element are unequal, the equation is unbalanced. Reversibility and exothermic nature are different properties of a reaction; they do not describe whether atom counts are balanced.
