We are given five scenarios, word equations, and then the net ionic equations, the net ionic equations may or may not be correct.
00:09
And we have to indicate whether they're true or false.
00:12
First, we're told that magnesium chloride reacts with sodium hydroxide.
00:16
We're given the following net ionic reaction.
00:25
Those are both aque, and we're told that the precipitate is magnesium hydroxide.
00:33
And we can say that that one is true, although magnesium hydroxide doesn't always precipitate.
00:38
I'm going to go check solubility of m -m -g -o -h.
00:51
Get them out of the silverware right there.
00:58
What is the solubility of m -g -o -h? not very soluble, so that will be a precipitate.
01:07
What did i write there? that should be 2s.
01:13
So that one looks like it's true.
01:15
What else am i supposed to do? i'm select true or false.
01:22
Okay.
01:23
Good.
01:24
Next, our next statement, ammonium sulfate and barium nitrate.
01:31
And my netionic equation is given as my favorite precipitation reaction to do in the classroom...
