Question

Giving examples, state the difference between balanced and unbalanced chemical equations.

Answer 1

Sr. No.	Balanced chemical equation	Unbalanced chemical equation
1.	A balanced chemical equation has an equal number of atoms of different elements on the sides of reactants and products.	An unbalanced chemical equation has an unequal number of atoms of one or more elements in the reaction.
2.	In a balanced chemical equation, the sum of the masses of the reactants is equal to the sum of the masses of the products.	In an unbalanced chemical equation, the sum of the masses of the reactants is not equal to the sum of the masses of the products.
3.	It obeys the law of conservation of mass.	It does not obey the law of conservation of mass.
4.	Example: \[\ce{Zn + H2SO4 -> ZnSO4 + H2}\]	Example: \[\ce{H2 + O2 -> H2O}\]
