How do you balance a Class 8 equation?

Steps in Balancing a Chemical Equation

1. Count each type of atom in reactants and products.
2. Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances.
3. Repeat steps 1 and 2 until the equation is balanced.

Why must we balance equations?

Answer: Chemical reaction is just a rearrangement of atoms. It can neither create nor destroyed during the course of a chemical reaction. Chemical equations must be balanced to satisfy the law of conservation of matter, that states that matter cannot be produced or destroyed in a closed system.

How do you balance a chemical equation for kids?

To balance chemical equations, think of both sides as a balance that can totter. When one side is heavier it falls and the other rises. The Chemical equation is the same thing: When the equation is balanced, neither the identities nor the mass of both the reactants and the products remain unchanged.

What is a unbalanced 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.
