Hello, everyone. Thanks for joining. We're going to practice predicting products for a complete for a double replacement precipitation reaction, and we're gonna do the net Ionic equations. I think we'll skip the complete this time. If you need to do that on you when you can try it, Okay? We're going to be given reactant. We're going to predict the products, including states, and then after we have a balanced chemical equation, we're going to write the Net Ionic equation. And we have two problems to Dio to make sure we recording. And we are. Okay, so problem number one Oops, I forgot. Don't have the problem in front of me. There it is. Were given to reactant. And a reactant are for the 1st 1 nickel too. All right. Which is a quiz and ammonium sulphide. Ammonium. So fight. And this has to have to and this is also a quiz. Now we need to predict our products. I like to use the general format, and I'm gonna go and make a little orange up here. Ah x plus b. Why? Where nickel is a chloride is x ammonium is be and sulphide his wife. Our products will be in the format up a why plus B X. Let's go ahead and put her try to predict our products. A is nickel and it is the nickel two. Plus, I am. So I'm gonna put that up there. Why is sulfide and sell fighters a to minus? So that is a good chemical equation, and I'm going to raise my charges. I just need those to write my formula. My good formula should say not equation. Okay, My second product is going to be be which is an age four and X, which is CEO, and this is plus one and minus one. So that is also a good chemical equation. Now I need to assign states, and we know that ammonia and chloride both always contribute to sally ability. So that one's a quiz. And we also know that most soul fights are insoluble, and this is no exception. Now, if you'll recall when we're doing precipitation reactions, we should have three a cues and an ass three accusing an s which we dio now we need to balance this chemical equation, and I'm gonna do this balancing by inspection and I can see that I have to chlorides and to ammonium. So I do too right here. This is a balanced chemical equation. Now we've done the complete Ionic equations in the past, and we've split all of our accuse into its associated ions, crossed off the Spectators and then copied down the equation without the Spectators to get her net Ionic equation. This time we're going to start with putting our precipitate formula right here. And that's this. And then we're going to put the two contributing ions. The cat ion is nickel, which is right there. Got a two plus charge and it's a quiz plus sulfide. It's right here. We have a two minus charge and it's also a quiz. So it's that simple. Okay. For our second problem, I'm going to switch to a different blue. We're given the following chemical equate or brawling reactions A man and all three to Yeah, So we've got manganese to nitrate plus sodium, boss, fake. And these were both a Chris, remember, a x B Why equals equals yields a Why be x So a is manganese. And why is Pio for Magan eases two plus phosphate is three minus. So the formula we're going get will be mn three peel for two and our second product will be in a and in all three, both of which are always soluble. So that's in a queue. Phosphates tend to be insoluble and manganese. Um, to phosphate is no exception. So now again, I have three a cues and in s a a que Let me get here a que a que a que and an s And again we're going to Oh, I better balance this one. This one's gonna be a little tougher to balance that. I'm gonna start by looking at this man Younis three right here. Here, I want to make a three. I'm gonna put a three. So I've got three manganese on each side now, three times to I've got six nitrates, so I'm gonna put a six right here, and I've got three someone to put two right here. My coefficients from left to right are 32 one and six. Let's clean this up a bit, so it's a little bit easier to read even with my very questionable penmanship. And last but not least, we're going to write our Net ionic equation again. We're gonna do this by writing the formula over person to precipitate. And here's my soul, my manganese. And here's my prostate. I have three mn two plus Don't forget the states, plus to your pores three minus. Don't forget the States. So here the Net Ionic equations for each one of our two problems in here are the products and we bounced each equation. Thanks for watching.
