Reactions and our first reaction is ammonium sulfate and berym nitrate and we're given that solutions of these are reacting and of course this will precipitate to my favorite precipitate reaction for use in the lab berym sulfate and ammonium nitrate i will need a two here and that should be balanced so this reaction will occur.
01:22
It says, and then we're asked to choose whether or not the stated reaction corresponds to the expected reaction.
02:14
No stated observation.
02:23
Well, let me see.
02:29
So i think the stated observation for this one is c -a -2 plus 2.
02:45
To, did i write something down? that's not right.
02:58
This reaction will occur and you should choose in the expected is for the net rionic will be barium plus sulfate yields barium sulfate.
03:42
And i'm going to make a note here.
03:49
The stated reaction wasn't provided.
04:07
Okay, second reaction is calcium acetate reacts with sodium carbonate.
04:31
And here my products will be calcium carbonate and sodium acetate.
04:56
And i will need a two here.
05:01
Hang on a second.
05:18
Okay, it's very low.
05:20
So that will be solid.
05:21
Okay.
05:23
Then i am, i do have a stated reaction and that's calcium 2 plus.
05:43
Plus, and this is wrong.
06:07
So you should select false.
06:10
This is the wrong answer.
06:18
The correct answer, i'll just jot it down because this has not been uploaded very correctly and clearly...
