Question

explain balanced and unbalnaced chemical equation in long answer

Answer 1

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

A unbalanced equation is an equation for a chemical reaction in which the number of atoms for each?elementsin the reaction and the total charge are not the same for both the reactants and the products. In other words, the mass and the charge are not balanced on both sides of the reaction.

Answer 2

The chemical equation needs to bebalanced so that it follows the law of conservation of mass.
A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side.
 Balancing chemical equations is a process of trial and error.
Example:
2 AgI + Na2S → Ag2S + 2 Nal

It is an unbalanced equation (sometimes also called a skeleton equation). This means that there are UNEQUAL numbers at least one atom on each side of the arrow. By the way, a skeleton equation is not wrong, it just hasn't been balanced yet.
