So we're balancing this equation.
00:03
We've got nh3 plus naocl producing h2o, n2h4, and nacl.
00:17
Well i always like kind of dividing my reactants and products and then sort of listing things out.
00:22
So in the ammonia there's one nitrogen and three hydrogen.
00:27
I'm going to put brackets around that and treat it like a compound.
00:30
So whatever coefficient i put in front of those values is going to affect both the nitrogen and the hydrogen.
00:37
And then we have naocl and we've got one of each of those.
00:43
And again brackets.
00:44
Then on the product side we've got water.
00:48
So we've got two hydrogen, one oxygen.
00:50
Brackets.
00:51
We've got the n2h4.
00:53
So two nitrogen, four hydrogen with some brackets and then nacl.
01:02
So now as i look to balance this i'm going to find the element that exists in the fewest places on each side first.
01:09
We've got a whole lot of those to start with...
