Question

how to balance equation​

Answer 1

Answer:

In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.

Explanation:

Answer 2

Answer :

The chemical equation in which number of atoms of each element are equal on both the sides of the equation ( reactant side and product side ) is said as balanced equation, but if an equation is not balanced or unbalanced, ( number of atoms are not equal on both the sides ), then the law of conservation of mass is violent, as balancing of equation is based upon Law of conservation of mass. So, the equation must be balanced.

Let us take an example,

$\bf{{KClO}_{3}\longrightarrow \: KCl + {O}_{2}}$

Here, the equation is unbalanced, Therefore, the way to balance the equation ( Hit and trial method ) is ,

First let's balance Oxygen first, by putting 3 before $\sf{{O}_{2}}$ and putting 2 before $\sf{{KClO}_{3}}$

$\sf{{2KClO}_{3}\longrightarrow \: KCl + {3O}_{2}}$

Therefore, Oxygen is balanced,

Then, as Potassium got unbalanced, So, we need put 2 before $\sf{KCl}$

$\sf{{2KClO}_{3}\longrightarrow \: 2KCl + {3O}_{2}}$

Therefore, Potassium is also balanced, and while balancing Potassium and Oxygen Chlorine also got balanced on both the sides.

Therefore, the balanced equation is

$\bf{{2KClO}_{3}\longrightarrow \: 2KCl + {3O}_{2}}$
