Dear students, two compounds of nitrogen and oxygen contains nitrogen and oxygen as given.
00:08
We have to see whether they are obeying law of multiple proportions.
00:16
Now as for law of multiple proportions, when two elements combine to form two or more different compounds, then the different masses of one substance that combines with the fixed mass of the other element, bear a simple ratio to one another.
00:31
This is our law of multiple proportions.
00:34
Again saying, when two elements combine to form two or more compounds, then the different masses of one element that combines with a fixed mass of the other, we are a simple ratio to one another.
00:46
Now let us see here, the ratio between nitrogen and oxygen in compound one, let us find out.
00:53
Here, nitrogen and oxygen is 1.
00:57
1 is to 2 .856 1 is to 2 .856 and here it is 0 .4378 is to 1 nitrogen in second compound.
01:18
Now what we do is we will keep the nitrogen amount fixed.
01:22
So here it is 1.
01:23
In this case it is 1.
01:25
Here we will make it 1...
