▶⏩ What is balanced chemical equations?¿

↪➡ Those chemical equations has an equal number of atoms of different elements in the reactants and products side, is known as balanced chemical equations.✔✔.

▶⏩ Why should chemical equations be balanced?¿

↪➡ The chemical equations be balanced to satisfy the Law of conservation of mass in chemical reaction.✔✔.

=> [ Law of conservation of mass state that → Mass is neither created nor destroyed, it is always conserved in the chemical reactions, therefore mass of reactants= mass of products].

▶⏩ For example:-)

↪➡ Zinc metal reacts with dilute sulphuric acid to form zinc sulphate solution and hydrogen gas.
=> Zn + H2SO4 → ZnSO4 + H2.

↪➡ Hydrogen burns in oxygen to form water.
=> H2 + O2 → 2H2O.

↪➡ When carbon burns in oxygen to form carbon dioxide.
=> C + O2 → CO2.

↪➡ When nitrogen and oxygen are heated to a very high temperature,they combine to form nitrogen monoxide.
=> N2 + O2 → 2NO.✔✔.

Answer 2

when the no. of atoms of each element r equal in both reactants and the products then tha chemical equation is a balanced chemical equation.it should be balaced to obey law of consrvation of mass that matter can niether be created nor be destroyed.eg-
cu+znso4----> cuso4+zn
2mg+o-------> 2mgo
kI+Pb(nO3)2------->KI2 +KNO3
2h2+O2---------.2h2O
