Question

What is a balanced chemical equation?

Answer 1

Balanced chemical equation

Explanation

• The chemical equation which is according to the law of conservation of mass, it is called a balanced chemical equation.
• The law of conservation of mass states that "the mass of the reactants in a chemical reaction must equal the mass of the products."
• It means that the number of atoms involving in a chemical reaction must be equal on both the reactant as well as product side.
• The example of a balanced chemical equation is as follows:

$2H_2 + O_2\rightarrow 2H_2O$

• The number of Hydrogen and oxygen atom in the reactant side is 4 and 2 respectively, whereas on the product side also it is 4 and 2.

Answer 2

A Balanced Chemical Equation Involves:

• It contains the number of moles of the reactants and products that are involved in the reaction.

• It contains the number of molecules of the reactants consumed and the products that are produced.

• Mass of each of the reactant that is consumed and product that is produced.

• In order to write a balanced equation correctly we must make sure that we mention the states of the reactants and products.

• Products are written in the order of solids liquids and gasses respectively.

• An equation that is unbalanced is called as skeletal chemical equation.

• We must always make sure that our balanced equation contains equal number of products and reactants on both sides.

• Example of a chemical Equation that is balanced: 2 H2(g) + O2(g) ----> 2 H2O(l)
