What is a balanced chemical equation? Why should chemical equations be balanced?
Answers
Answer :-
Balanced chemical equation
When the total number of atoms on the reactant side and the product side is equal, the equation is called a balanced equation.
Need for balancing a chemical equation
A chemical equation needs to be balanced because a chemical reaction is just a rearrangement of atoms.
Atoms themselves are neither created nor destroyed during the course of a chemical reaction.
The chemical equation needs to be balanced to follow the law of conservation of mass.
A balanced chemical equation is a type of equation where the atoms of the elements in both side are same. In other words, the atoms of reactants and products must be same.
For example :- Mg + 2HCl ----> MgCl2
A chemical equation must be balanced in order to follow the law of conservation of mass. According to law of conservation of mass, mass of atoms can neither be destroyed nor created during a chemical reaction.
