We are asked to write the balanced complete and net ionic equations for the following.
00:06
It's a lot of writing, so i'm going to get going.
00:18
In black, i'm writing down what we're given.
00:28
This one is already balanced.
00:33
My complete will be crimson.
00:51
It's important when you're doing these not to forget any of the parts.
00:56
When you're doing just a normal, regular old, complete net ionic precipitation reaction, each one of the four species represented on the reactor, inside of the complete ionic equation need a charge and a state label.
01:23
Now i'm going to cross off my spectator ions, the light color, and in blue i will write my complete ionic equation.
01:35
I don't know why i just noticed a mistake.
01:37
I don't know why i put a 1 plus there.
01:46
There we go.
01:51
Ag plus.
02:00
There's one.
02:03
Number two is calcium sulfide reacts with copper 2 chloride and my product will be copper sulfide and calcium chloride.
02:31
These are all given.
02:41
Aq, aq, s, aq.
02:46
Okay, that one's still balanced.
03:12
Don't forget to point your coefficient on your number as a coefficient.
03:19
I did not write the whole thing down here.
03:22
I see.
03:25
This was c -u -s.
03:28
Sorry about that.
03:45
I'll put the a -q down here.
03:48
And then again, we will cross out our spectator ions, which will be these two.
03:55
And i like to write my cat ion first.
04:01
Oh, i did that wrong.
04:16
There we go.
04:20
Got it.
04:21
Now, i like to write my cation first...
