Mercuric iodide dissolves in excess of KI and forms (a) $\mathrm{Hg}_{2} \mathrm{I}_{2}$ (b) $\mathrm{Hg}$ (c) $\mathrm{K}_{2}\left[\mathrm{HgI}_{4}\right]$ (d) $\mathrm{K}\left[\mathrm{HgI}_{2}\right]$

When forming an ionic compound to determine the correct formula of the ionic compound, we need to make sure that the ionic compound is neutral. To make sure that it is neutral, we need to no the charges on each of the ions forming the ionic compound. So if we take potassium, which has the simple K. And look at its placement on the periodic table, it is in Group one A. With one valence electron, so it typically wants to donate its one valence electron to form a one plus cat eye on iodine is in group 17 or seven A. And it just needs one valence electron in order to achieve an octet. So it typically wants to form a one minus an eye on, so when potassium and iodide come together, we just need one of each of them. In the ionic formula is K. I.

Hey, guys, lets your problem 13. We need to right on water the systematic names for the given symbols and we need to write the formula for the given compounds. Let's do that. The systematic names are the first one is having carbon and sulfur in the compound and the name of this compound is carbon di sulfide. Then we have flooring and oxygen in this compound and the name is declaring hip dockside. The prefix die comes from this too. And Hector comes from this seven. Then we have xenon. Exactly. Alright, This perfect sector comes from the six atoms of chlorine. Then we have a minimum and sell firearms which is composing this compound. The name is Alan themselves fit. Then we have chromium and Florence, which is making up this, uh, compound. And we know that Florian is having negative one charge and there is three of them. So to neutralize this negative three challenge from me, um, is having positive three observation state. Therefore the name is chromium three chloride. Then we have potassium bar outed. Yeah, Next, the formulas to the compound name is sodium sulfite. Therefore it will be made of sodium and sulfur atom and the symbol is and I do s 03 Then we have very, um carbon it. Therefore, we will have barium ion and carbonate town in the name of Simple is B S C 03 Then we have iron to chloride iron to means F two plants and Tony realize this is a P two plus we have Florida. There should be two of that. And if you sell to is the symbol then we have sodium sulfite. Therefore we will have sodium on and tassel fit down and and I do it So it's 203 is the simple for that? Then we have die out in the paint oxide. Therefore, there will be two Aydin and five oxygen atoms which will be composing this compound. Yeah, and the assemblies I do. Or five. Then we have a tie nitrogen oxide. Therefore there will be two nitrogen atoms and one oxygen atom into this is the formula for this given compounds

Hello, everyone. My name is in this picture we have. These are falling and the right name Bob Sizzling is wrong. So to answer this question, you must ride the name off each off the flooring from the 1st 1 we have See you on ice so they only off on is negative on and see you is posted. One Sorry posted, Mom. So we can write. Knows the name is Q bra's because we'll see you is posted. One. It's called the Cube ra's and on East schooled on line. So this is a correct name here. Inches over is each one of them is negative, Mom. So the iron is that connected to three off them, it will be posted. Three. Salaam's a name will be armed three. And this cold hydrogen Zoetis space sulfate. Yeah, the last one cr two or 7 80 charges negative toe and the magnetism is postive toe. So the name is darkly magnesium, and the magnetism has only one oxidation. Magnesium die crew made in the few bra's. Usually, when were like eight. We can like Cuba a certain line, or we has another name, which is cover on. All right, so falls off them. He's great. Thank you.

In this problem. We have five, um, compounds and we're just defined there. Molecular messed, except we're going to use these medals and a kind of special, um, naming of combat. So really hear words or endings like us, an IQ such as there is, like the fairest I on the Mir Carrick I on the standards high on. So yeah, us and Nick, Let's just quickly review what these mean. These are this. This is the old naming some system, and it's not too commonly seen here. But let's still like learn what it is. So these are all multi violent medals as they have multiple charges and us, and it is used to denote which, um, charges being used. So us typically is referring toe the charge. That's just like cluster and value while it is the one that's, um, greater and value. So, yeah, um, so this is why it's not so coming. You commonly used because it assumes that you know which, um, charges are like, you know, what's charges that I on can take and then to be able to determine which is the larger one, which is the less valued one like less like the smaller one and value. All right, so the 1st 1 that we have here is Gareth cell feet. So let's look at iron over if you're ironist. Ferris also uses different prefixes. But we know Ferris is iron, and it's the one with a less charge. A less of a church. So two plus, we have iron two plus and sulphate. And we know sulfates is a polje, atomic ion. So four with the tu minus church. And because both of these ions have the same home absolute valley of charge, we only need one of each. Adam and Paul Atomic Adam too come together. Many compound. So it would just be Effie s 04 And now all that's left is first to sum up the molar masses of each Adam present here. Okay, so we have iron a sulfur and four oxygen's. So to do that over here, I am So for. And oxygen? Well, just some of molar masses. So air has a small amounts of 55. And this is all this. Here's old grams per mole. So a not be writing units, but it's all assumed to be in grams promote. So more mass of iron has always think it's 55.845 The mill, a massive sell for is 32.6 It's and the molar mass of oxygen 15 point to mine my life for. But because we have, um, four oxygen atoms, we must want to buy this number by four. And if we sum up all of these values, what we get is 100 and 52 grams per bowl. All right, now that we get the flow, you can continue on next. We have Mercury, Rick iodide Mark your IQ, I thought, Mark your It's like Mercury and we have the pre Suffolk's. That means it's the greater Church two plus church here. So we have h g two plus an iodide, which is just I minus. All right, so here we can see that we would need to iron sights to me. Um, Bond with this break, Yuri, so we can have basically no more church for men. It's HD h g I to right. So now let's find the molar mass of this club. So we have one Mercuri Uttam in two iodide, or I'd I'm Dean Adams. Here it's grams per mole just going to do a quick addition. So morass of mercury is 200.5 mine, Gramps from on the one for iodide is 1 26.9 camps promote and if we add, But let's not forget this is times chew. And now if we have those together, be a 400 54 play four grams per mole. All right, Next up we have Stanic oxide, Stan Oxide So with my beauty, but were tricky. But Stanic is referring to 10 s then, like the old latam word for it promising me. And because it's Danic, it should be the greater charge, which was the four plus. Okay, so now that we have sn four plus an oxide, which is loneliness 02 minus, we cannot determine what the compound should be. All right, so looks like me to oxygen's here to cancel out that charge. That four plus sn Oh, too. So let's quickly calculate the molecular molar mass vamps promote Kate. So 10 has a more mass of 118 0.71 An oxygen has a mullah mass of 15.9994 And let's not forget we have to. Oxygen atoms came now upon ammunition of all of these moos, we get 100 and 50 0.7 grams per mole. Similar mass of Stanic oxide. Okay, next up we have cobalt as chlorate. Cobalt is cord, right? The charge for cobalt, um is an us. So it's the less charge, which is two plus. So we have a coded cold Baltics chlorate. That's a bit funny that cobalt is court. Now we know chloride sees chloride is one minus good and persevere trend. But all of the non metals We need two of them so we can neutralize discharge to here They're cobalt is chloride kidding? It's find the mold of us Cobalt. All right, add this up home. All masks for Claude is 58.9332 Did you stay put? The mullahs mass for chloride is 35 35.45 to 7 and it's all basically terms to you have to Adams of it chain that gives us 129 0.83 need 86 miles grams per mole of cobalt is court. Now last, we have, um, Cooper IQ nitrate Kubrick treat All right. So Kubrick means the greater Charge two plus church Cooper two plus a nitrate we know is a poly atomic ill. And no, three three with a one minus charge and two plus one minus. We need two traits to bind with a copper Adam together Cooper, night treat. And no three. We'll just insert some brackets. Nice move to there. That's a you that I should probably your rates. Cooper. Rick. My tricked. Okay, so you have a copper, Adam nature gin, Adam oxygen and listen is gonna be fun. Grams per mole was a G. Okay. Way of one copper. Adam, which has more mass of 63 0.546 We have George is 14.647 Our 674 But here we can see we have to nitrogen animals so multiplied by two. Next, um, his oxygen, which is the 15.9994 grams per mole. And we look the molecular formula. Oh, we have six oxygen on him. So, like, it's some multiplied by six fleet. At this up, we get 180 stuff in points. Five grams per mole off kubrick nitrate
