What is a balanced chemical

What is a balanced chemical ?Why should chemical equations be balanced?

A chemical equation is a symbolically represented chemical reaction in the form of symbols and formulae, with the reactant entities on the left and the product entities on the right.

A chemical reaction occurs when chemical bonds between the atoms or groups of atoms of reacting substances are broken, and the atoms are rearranged to form new bonds, resulting in the formation of new substances.

For example,

Nitrogen reacts with hydrogen to ammonia. The chemical reaction is as follows;

N2 + 2O2 2NO2

To obey the law of conservation of mass, which stipulates that mass cannot be created or destroyed, chemical processes must be balanced. As a result, the total mass of substances prior to the chemical reaction must equal the total mass of reactants after the reaction.

Law of conservation of mass,

The law of conservation of mass states that in a chemical reaction, mass is neither created nor destroyed.

The following rules should be followed to balance the chemical equation:

• Write the unbalanced equation:

On the left hand side of the equation, the chemical formulae of the reactants are provided.

On the right-hand side of the equation, products are mentioned.

An arrow is drawn between the reactants and products to show the direction of the reaction. Arrows will point in both directions when a reaction is at equilibrium.

• The equation must be balanced.

Once one element is balanced, move on to the next until all of the elements are balanced.

By adding coefficients in front of chemical formulations. Subscripts should not be used because they will alter the formulas.

• Indicate states of  reactants and products.

For gaseous substances, use (g).

For solids, use (s).

For liquids, use (l).

For species in solution in water, use (aq).
