00:01
For this problem, we are going to be looking at four acid -based reactions.
00:04
We are going to write the balanced chemical equation, the complete and net ionic equations.
00:13
Let's begin.
00:14
We are given the reactants.
00:16
So for our first problem, we are given ammonia, which is nh3, and we're told it's aqueous.
00:25
That's given in the problem, reacts with nitric acid.
00:31
Hn -o -3, which is aqueous.
00:36
Okay, so our job is to predict the products.
00:50
Okay, and then we're going to write our complete ionic, which i'll do in, i'll do that one in this bright color.
00:58
So this is weak, so it doesn't, it's a weak base.
01:01
So it does not ionize.
01:03
So we've got, we're going to leave that.
01:08
When we're dealing with our acids, we're going to, when we ionize this, this is a strong acid.
01:15
Nitric is a strong acid.
01:16
So i'm going to ionize that as the hydronium ion and the nitrate ion.
01:31
Now, that means i'm going to have to add a water to the other side.
01:34
So i've got nh4, and then i'm going to continue down here, n03.
01:47
And remember, i added an h2o to get this value.
01:55
Next, we cross out our spectators.
01:57
There should only be one spectator here.
01:59
Well, i wanted to switch colors for my spectators.
02:03
My n .o .3 are spectators.
02:06
And my net ionic equation, we just rewrite without our spectators.
02:17
Not forgetting our states.
02:31
There's our first one.
02:34
And now let's do our second problem.
02:37
And we'll start with this color again.
02:39
And for our second problem, we are given.
02:43
Aqueosperium hydroxide.
02:48
Whoops, i need a two right there.
02:56
Is reacting with hydrochloric acid, and the products will be aqueous barium chloride and water.
03:15
Okay, so let's do our complete ionic equation.
03:20
Oh, i better balance this first.
03:22
I'll go ahead and balance it with this color.
03:26
There's a two and a two.
03:29
Okay, so now let's write our complete ionic equation, barium.
03:37
You know what? i'm going to leave the states off this and then put the states on on my net ionic equation.
03:46
And that should be a 2 plus.
03:51
So i'm going to leave the states off this and worry about the states when i do my next phase of this.
03:58
But i'm going to make sure to get my charges anyway.
04:07
My quantities.
04:19
How nice was that? that all fits on one line when i don't put my states in.
04:23
And then we'll cross off our spectators...
