Hi, so we are to balance the given reactions here.
00:05
First one, we have chlorine gas reacting with o2 forming cl2o7.
00:12
So let's balance the number of oxygen first.
00:15
We'll write 2 here and then 7 in here.
00:18
That means you also have to write 2 here.
00:21
Now, let's count the number of elements in both sides of the equation.
00:24
Chlorine, we have 2 times 2.
00:26
This is 4.
00:27
Oxygen, we have 7 times 2.
00:30
That's 14.
00:31
On the product side, we have chlorine, 2 times 2.
00:36
Oxygen, we have 2 times 7.
00:39
This is also 14.
00:41
The number of elements in both sides of the equation are now equal.
00:45
So that means this is the balance equation for this reaction...
