Okay, so the first thing i do when i'm going to balance an equation is first decide how many of each element i have on both sides.
00:08
And then i'll go and try to figure out how can i make everything equal.
00:12
So here on our reactants side, we have one nitrogen.
00:18
I have three hydrogens and i have two oxygens.
00:24
On my product side, i have one nitrogen.
00:30
I have two hydrogens.
00:35
And then i have two oxygens.
00:37
Okay? so don't forget we add those two together.
00:40
So now we have to figure out what needs to be balanced and how can i do that? so we'll see here that your hydrogens are probably the first place we need to start.
00:53
So in this case, we need to get three and two to equal each other.
01:00
So what i want to do here is i'm going to start by multiplying them by each other.
01:09
So you have two on one side.
01:10
So i'm going to take three times two.
01:12
That's going to become your coefficient up here.
01:16
That changes my nitrogen to two and it changes my hydrogen to six.
01:22
Over here i'm going to take two times three.
01:26
So now, let's.
01:28
Let's put our three here.
01:32
So now we have six hydrogens...
