good evening________❤️❤️❤️






To understand how to balance chemical equations let us take an example.

MnO2 + HCl → MnCl2 + H2O + Cl2

In the example, let us assign each component of MnO2 as ‘a’ , component of HCl as ‘b’ , components of MnCl2 as ‘c’ , components ofH2O as ‘d’ and components of Cl2 as ‘e’

(a)MnO2 + (b)HCl → (c)MnCl2 + (d)H2O + (e)Cl2

Since the component of Mn in ‘a’ and ‘c’ is one therefore a=c

The component of O in ‘a’ is two and in ‘d’ is one therefore 2a=d

Component of H in ‘b’ is one and in ‘d’ is two therefore b=2d

Component of Cl in ‘b’ is one , in ‘c’ is two and in ‘e’ is two therefore b=2c+2e

Let us assume ‘a’ as 1

Then c=1, d=2. b=4, e=1

On substituting the values of a, b, c, d, and e in the equation, we will get the balanced chemical equation.

MnO2 + 4HCl → MnCl2 + 2H2O + Cl2.

Hello dear I am tanwi sorry for a late answer but I was tension about Adar card



Your answer

we can balance all type of chemical reaction by seeing the left and right side of chemical reaction and by noticing the changes and by balancing it like if in left side it is 4 oxygen than and in right side it is 2 oxygen than add 2 in right side it will be 4 oxygen in both side.

Any help say me I will help you but now I am in tension of Registration
