Here we have a list of equations that we have to complete and figure out the products and then their states.
00:08
We're starting with lead and sulfate ions.
00:11
That'll come together to form solid lead sulfate.
00:17
Next we have copper nitrate and sodium sulfide.
00:20
That will form insoluble copper sulfide.
00:23
Plus you will have sodium and nitrate ions in solution.
00:30
Let's balance everything and there we go.
00:32
Now we have iron nitrate and sodium hydroxide.
00:37
This will form insoluble iron hydroxide.
00:42
And you will have sodium and nitrate ions in solution.
00:50
Let's make sure everything is balanced and there we go.
00:55
Now we have aluminum hydroxide combining with nitric acid.
01:00
This is going to form aluminum nitrate and water.
01:07
So now we have to balance it.
01:10
We have three nitrates so we're going to need to put a three in front of our nitric acid.
01:18
And then that means we have to add a three in front of our waters...
