00:01
So we had to find out which of the foreign pairs of chemical compound have the same empirical formula.
00:06
So first of all, for our empirical formula, we're looking at the pharma with the simplest ratio between all the numbers in the formula.
00:17
So we're looking at simplest ratio.
00:19
Okay, so for first one, we have c2h2 and also c6h6.
00:24
We have to simplify it.
00:26
So to make sure we have the simplest ratio.
00:29
So for c2h2, the simplest ratio will be ch because they can be simplified by 2.
00:37
And also for c6h6, again, all the molecule, whole molecule can divide by 6 and then we have c8 as well.
00:45
So both of them, they have same empirical formula.
00:49
Second one, we are c2h6 and also c4h10.
00:53
We are going to simplify that, how we should be able to find the as equal to c83 at the m5.
00:59
Simplest empirical formula, and then we are c2h5.
01:03
So from here, we can see that they are different, so we don't have the same empirical formula...
