Question

1. Define the following:
(a) Unbalanced chemical equation
(b) Balanced chemical equation​

Answer 1

Answer:

Unbalanced chemical equation:

A chemical equation in which the number of atoms of each element in reactants is not equal to the number of atoms of each element present in product.

Balanced chemical equation:

When an equal number of atoms of an element is present on both sides of a chemical equation, the equation is balanced.

Answer 2

Explanation:

A) Chemical equation can be divided into two types: balanced chemical equation and unbalanced chemical equation.

If the number of atoms of each element in reactants is not equal to the number of atoms of each element present in product, then the chemical equation is called unbalanced chemical equation.

B) A chemical equation is a written symbolic representation of a chemical reaction. The reactant chemical(s) are given on the left-hand side and the product chemical(s) on the right-hand side.

The law of conservation of mass states that atoms can neither be created nor destroyed in a chemical reaction, so the number of atoms that are present in the reactants has to balance the number of atoms that are present in the products.
