Right there.
00:02
In this question, we are given this chemical reaction, and it's shown that it's producing the nitrogen and the water.
00:09
Well, in theory, all reactions are reversible.
00:29
So again, this is in theory.
00:30
Some of them are not terribly practical.
00:32
For example, when we burn wood by combining it with oxygen, we produce carbon dioxide and water.
00:39
We cannot reverse that very well ourselves.
00:42
We can't take carbon dioxide in water and produce wood and oxygen.
00:47
However, plants essentially can't.
00:50
It's a little bit more complex, but in theory, all reactions are reversible.
00:55
So the reverse of this reaction could also, at least in theory, occur.
01:03
So that would be four nitrogens, which are gases, reacting with three, water, also a gas, to produce two ammonia, and three and two.
01:24
So again, in theory, all reactions are reversible...
