Write molecular equations for each precipitation reaction that will occur.
00:05
If no reaction occurs, we're asked to write, of course, no reaction.
00:09
I've written each substance down to save time.
00:12
So let me begin.
00:14
These are solutions.
00:18
These are all aque.
00:20
In every one of these, these are a cute.
00:30
Copper bromide and lead to acetate.
00:44
And my products will be lead bromide and.
00:53
Proper 2 acetate.
01:03
There's a 2 there, and this is an aq.
01:08
I will need a, i've got 2, 2, 2.
01:14
Okay, that one's already balanced, and now i'm just going to go grab a solubility tab here.
01:23
I'm sure that my solubility, let me do this, is pb, br.
01:32
I'm sure the lead to bromide is not soluble.
01:36
It's considered to be insoluble in water.
01:58
So there is my answer with all my states.
02:01
States and balanced, right there.
02:04
Next, we have lithium sulfide and strontium iodide.
02:17
My two possible products, i2aq, goofy, will be strontium sulfide and lithium iodide, which will be my soluble product and would need a two.
02:38
Let me get back to my solubility tab.
02:43
Srs.
02:44
Is srs soluble in water? this is soluble.
03:11
I wish i had your rules that you were using.
03:19
Does sr2 or srs, it is slightly soluble in water? my source lists srs as slightly soluble as slightly soluble.
03:41
You need to check your source to decide for sure.
03:52
Check your source of solubility rules to verify it...
