Here we are asked to balance this equation, right? naoh, then h2so4 is given to us.
00:09
That gives na2so4 plus h2o, simply.
00:17
So now na is 2 here, right? on the right hand side, right? so what we simply do is, we will multiply it by 2, right? right.
00:32
So now here what it becomes.
00:37
Ok.
00:38
So h2 is there.
00:39
2 is there.
00:40
This is balanced.
00:41
Ok.
00:42
And this is also balanced right now.
00:44
But o is 2.
00:47
O is 2.
00:50
H is 2.
00:53
O is 2 plus 4 we have.
00:56
And h is 1 plus 2 i am writing like this.
00:59
So this is becoming 6 and this is becoming 3.
01:03
Right.
01:04
Here okay and s is one only right so oh and s on the right hand side it would be 4 plus it is 4 plus 1 is 5 here right and here h is going to be 2 and for s it it is 1 only, right? so, this and this actually balanced.
01:40
S and s is balanced already, right? what is not balanced right now is, okay, so this is 2 plus 2, okay? because 2oh, right? so, it becomes 4.
01:55
Now, we want 2 on the right hand side also, right? h.
02:02
Now, to balance it, we will be multiplying it by 2, right? right.
02:08
Because 2 h2o would be making it 4 here...
