 Okay, so now we've got another one of these molecular total net ionic equations, okay? So we've got these four, well I guess it was written differently than this, it was given to us the molecular equation. Okay, so this was given to us, right? And we want, this is the molecular equation, we want to break this up into its total ionic equation, okay? So molecular, okay? So calcium nitrate, we remember what calcium's ionic charge is, hopefully. Well I guess the first thing we want to do is balance the equation, which it's not balanced right now, right? So we've got two nitrates here and three nitrates here. So we're going to have to do something to this. We're going to have to multiply this by three and this by two over here. So now we've got six nitrates and six nitrates. But now we've got three calcium's and only one calcium, so we're going to have to put a three there, okay? Now we've got three sulfates, three sulfates, two cobalt, two cobalt, three nitrates, three nitrates, three calcium's, three calcium's, okay? So everything's balanced now, okay? Now we're going to do our total ionic equation. Oh, yeah, this one should say aqueous, sorry. Okay, so now we're going to do our total ionic equation. Remember anything that has aqueous after it? We're going to break up into its ions, just like we did last time. Calcium we know is a two plus ion. We're going to put the physical state aqueous after it. So how many do we have? Three times two nitrates, right? So we've got six of them. Six and oh, three minus. How do I know it's minus? Just minus one? Well, if I haven't memorized it yet, which I should have, I would realize that calcium is two plus and there's two of them for each calcium, so it must be minus, okay? Or in other words, three times two is six, six times one is six, okay? We've got to put aqueous after that. Now let's go to the cobalt, okay? What cobalt is this? Well, we've got to remember some things, I guess. We could remember that sulfate ion or ionic charge is negative two. If we remember that, then we could get this directly. Or if we come over here and now we know nitrates is negative one, there's three nitrates. That must mean cobalt is positive three, okay? So cobalt two, or two cobalts, you know, three plus aqueous. So notice how I'm putting my ions and how it's different than the way you were writing them on your paper, okay? And then we're going to have to add our sulfates to it. Three S04, two minus, that's a two. I'll show you. Look at the top. See how it's much different? Do you see the difference? Okay, you've got to write it this way. Okay, this is a solid, right? Calcium sulfate, so it's not going to break up into its ions. And now we've got this, which is aqueous, so it's going to break up into its ions. Remember, cobalt's cobalt three, and we've got three nitrates. And remember, nitrate is negative one, okay? So that's the total ionic equation. And remember, when we want to do the net ionic, we want to do the net ionic. We just take out what's on both sides, or what we call the spectator ions. Let's do that with a different color, maybe red. Calcium two plus on this side, no calcium two plus on this side, right? Nitrate minus on this side, three of them. Oh, this should be, sorry. This is, sorry, three times two. I'm surprised you guys didn't catch me, okay? So the reason I realized that there should be six is because I looked over here and there's six of them here. There was only three of them there, right? So, yeah, it's kind of a giveaway. So we've got six. We're going to cancel that out, six nitrates. With that, six nitrates there. Two cobalt three plus, with two cobalt three plus, and then sulfates we have over here, but none over here, right? So let's write our net ionic equation now. It's three C A two plus aqueous plus three S O four two minus aqueous plus three goes to three C A S O four solid. And if I were to ask you what are the spectator ions, you would say N O three minus C O three plus. Those are the spectators. Does that make sense? Make sense? Those are the ones that I crossed out. Yeah, spectators are what I crossed out. Any more questions before I shut off the video?
