Here in this problem, given a precipitate forms when acost solutions of iron three chloride and sodium sulfide are mixed together.
00:09
We have to first write a balanced molecular equation for this reaction.
00:14
Then we have to write the ionic equation for this reaction.
00:18
Finally, we have to write the net ionic equation for this reaction.
00:23
Now, first we will write the molecular equation.
00:26
Here is iron three chloride, f, e, c, l, 3, chloride.
00:30
3 aqua solution plus sodium sulfide n a 2 s is aqua solution and the products are f e 2 s 3 precipitated and aqua solution soluble ncl salt now we have to balance f e 2 so let's place 2 here now both sides of the equation have to uh i don't atoms.
01:04
Now we have two times three, six chlorine atoms.
01:08
To balance the number of chlorine atoms, let's place six here.
01:12
Now we have six chlorine atoms on the both sides of the equation.
01:16
Now we have six any atoms on the product side.
01:20
To balance it, let's place three here.
01:22
Now we have six any atoms on the both sides of the equation...
