Question

Easier method for Balancing chemical equations.
(Tutorial on Balancing)

Answer 1

The way school's teach balancing chemical equations is retarded, the one I would be posting below is called the factorial method of balancing chemical equations.

Answer 2

Let's take a simple example:-

Answer 3

\[\huge N_2 +H_2 \rightarrow NH_3\]

Answer 4

We don't the coefficients of each of the terms so let's assign them a variable

Answer 5

\[\huge aN_2 +bH_2 \rightarrow cNH_3\]
Like this :)

Answer 6

We know mass and atoms remain same on either side of the equation. Which is pretty obvious

Answer 7

So you make simple equations like we do in mathematics like below

For Nitrogen:-
\[\huge a*2=c*1\]

For Hydrogen
\[\huge b*2=c*3\]

Answer 8

So now we assume any value for any one variable , but for simplicity let us assume it is 1
We can assume any natural number

Answer 9

So, we assumed a=1
1*2=c*1
c=2

Answer 10

so c =2
b*2 = 2*3
b=3

Answer 11

We substitute the values of the variables in the equation

Answer 12

That is a=1 , b= 3 , c=2

Answer 13

\[\huge N_2 +3H_2 \rightarrow 2NH_3\]
If coefficient is 1 then we do not write it as in this case a=1 , i haven't written 1

Answer 14

Note:- If you assumed a value for a variable initially and the other variables are fraction , they must be multiplied by simplest whole number because , atoms are not in fractions

Answer 15

This method can be applied to even bigger reactions , and works accurately.
This method is better than the method taught in school , which is guessing(trial and error)

Answer 16

@ganeshie8 @ikram002p , what were you taught in school (just asking)

Answer 17

wow i like how u did it :3
well in school i cant remember if there was a methology about how to do it lol
but some how i can do it quick ( dnt know what ) :P

Answer 18

I will give you damn bigger reaction and do it quick lol

Answer 19

you can't by guessing

Answer 20

haha ok gimme :3

Answer 21

\[ K_2Cr_2O_7 + H_2SO_4 + FeSO_4 \rightarrow K_2SO_4 + Fe(SO_4)_3 + Cr_2(SO_4)_3 + H_20\]

Answer 22

@ikram002p

Answer 23

haha ok :P

Answer 24

You have to agree you can do it quick by the factorial method

Answer 25

ya i agree to that :D

Answer 26

nice :)
@lovelyharmonics

Answer 27

wait this is amazing thank you

Answer 28

Nice !
This is how balancing tools are programmed :)

Answer 29

@chmvijay what were you taught

Answer 30

what ?

Answer 31

^^ look up

Answer 32

yaaa thats looks nice :) good congrats :) but when reaction becomes bigger varaibles also become bigger :) for school kids its good way to learn but for hardcore chemistry by seeing only he should balance it :)
good well done :) hope it will help the OS students :)

Answer 33

yes
