What is the formula for potassium carbonatotetrachloromolybdenate(IV)? KMoCO3]Cla B KMoCO3ClaC KIMoCO3Cla] D Kz[MoCO3Cla] KIMo(COJ2Cl4]...

What are the formulas of these compounds? (a) potassium tellurite; (b) sodium arsenate; (c) calcium selenite; (d) potassium chlorate

So we're asked to write the chemical formulas for different chemical compounds. In our first case we have a cobalt two plus Hyon, we have four chloride annoyance and we have potassium so we need everything to charge balance out. So uh the complex ion is well known. So C. O C L four to minus. So we need to potassium is to balance that out to potassium ions. So this would become K 2, 4. In part B. We have uh one H 20. So this is uncharged. We have three ceo groups which are uncharged and we have bromide And we also have platinum two plus. So we need to borrow mites to balance out that charge. And this gives our chemical formula for part C. We have sodium ions, we have to sign an annoyance and we have to oxalate annan's and we have the three plus. So once again we need all the charges to balance out. So we have FE three plus to F E CN two C204 two. So that the total negative charge would be six miles positive charge of the three plus. So we need we need three. So dems to balance out the charge. And in our last part we have Uh three and H. three And we have one cl minus and we have an ethylene Diomede molecule. So ethylene di amine is uncharged and we typically express it as E. N. So we have one of those. Then we also have uh chromium three plus uh I on and we have iodide to balance out the charge. So we first write chromium, then we have chloride, Then we have our uh ethylene di mean, then we have NH three three, so we still have an access charger two plus, so we need I to and these give our final answers.

In this question, we need to write the formally off given compound. So the first compound that we've been given is but nationally, that truck, low commodity, state of cobalt is given to me. Right? So how are you going to write the common off? Initially? This is going to come first, since this is at a time. So this is going to be key and no from here, we're going to start the record because this part contains a transition element. And this is a in iron, right? So we have a truckload Oka body. That means chlorine is present four days and then we also have kobold, right? So we're going to start writing. See you being right now, we have been given that the balance, see or rather the oxidation Sudoku ball. Cleary's plus Right from that, we can calculate what these are Plates of potassium here is going to be. Could be no other chlorine existence minus Tehran oxidation feet. And since the four atoms of chlorine, this is going to become minus food and assist. Plus, so right, so we're just left with minus two over here. So we're just going to substitute that this is going to become a finance for this part. So moving one, the next component that we have is at glory. Try carbonite, platinum, The oxidation Stewart has given to rectal real might. No, this is our A nine part, and this is our get on board. So obviously this is going to come first. Maybe like the moment the nose instead is 1/4. This means that we have water, you know, given come home. So we have water and carbon. I'll stands for what? You're pretty, you intense. It's try. This is going to be three and then simply part of them. Tour. You're going to write BT it's to do the old three. Now let's fulfill the Valenti's your let's check if platinum present and plus two oxidation state or not, let's destroyed bromide. Your You're right Now. Both water and garden eye drops are neutral Liggins. So here the oxidation state is going to be zero and zero and this present and plus two oxidation state. But here with just written br right, this needs to be substituted with two in order to get the complete for middle. So what is a complete formula that's just right, This one's again. Beattie. It's too Oh, the o City b r don't This is a Courtrai card When I started, all right, moving on to the next part. Our next come Boehner's Sodium Dia Sinaloan, based off the Lotto City. And this is prison complex. Three exhibitions tonight. Soon this is occupying. Here's first. We're going to write the formal off this compound. They we have die a sign that means the end is prison. Jourdain's very means IDed and this auxiliary restaurants for auxiliary diet see toe hold, which is presently times. And this is indicated by our base break over your next start writing his leave. This is our transition metals of that going to composed and then I hooligans Sito, right? So, no, let's take a oxidation state into consideration. This is President. Let's create Finite is minus one and this is present full time. So we're going to multiply it and this is doesn't in my Mr Similar depended Plato, we get minus food minus two minus. So you But this is going to become simply my mystery. So here we need to write about three. And this is the giving for middle right Let's move one. The next component right over you. It is try. I mean, clue. It'll it's highly Daio mean, chromium you. I owed it. That's quite a large me, isn't it? Try Oh mean, this means that we have in its three group over your three times total. That means we have a CNN. It's how I mean highly die or be hurt. What is this speech to vegetal? And since it's a dia lean, we're going to have do in its two groups over your recall that this component see it three ch three is called anything so it kyleen comes from this. So this is Ah, it's island, I mean. And then we have chromium. I owed eight. So let's start writing the perimeter. Let's start with Koeman because that is us transition making over you. Then we have in its three, three times, including and then and it's stool the itch. PH, too. And it's we're done with odd. You're dyin over, you know, let's just strike via nine, which is I OD. Now. We need to take the oxidation state into consideration. The oxidation state off chromium beauties plus three ammonia is Tzeitel. Fiorina's minus one, and this is also present in zero. Right? So we have this present in just two oxidation states. We just need to write the two over here and read This is the solution or five questions.

So here we are asked to write complex science and in our first case we have cobalt three plus and we have to H two Os and we have to Oxley and Diane Alliance and as a result we can see that the net charge of this complex Would be 1-. And in order for salt formation we essentially need to counter ion which in this case would be our potassium calcium. In our second case we essentially have uh two means begins three insurers as Liggins and we also have a hydroxide and iron and we have chromium two plus so the net charge will essentially be a chromium one plus as a result and as a result since there's a net charge of one plus we need to counter ion to balance out the charge which will be done in the form of nitrate. In our third case we essentially have ammonium as our counter iron and we essentially have essentially see you cl four to minus, which is a very common, essentially complex science. So as a result, we need essentially to ammonium and as a result, we have the following complex science in part D, essentially we are having to athlete diamonds, We're having four chlorine chloride Annan's And we're essentially not going to have a specific counter island in this case. So cobalt three plus Would have to combine with the following. So it BEN two cl four. And we can see that the net charge would be 1- in this case. In our last case we have three H 20 three floor rides And we have cobalt essentially three. Cobalt three plus. And we can see that the net charge would be equivalent to zero. And this gives our final answers.

Getting to everyone work for which has you right of the formulas or some box on And for King So young Tell there till there right will be your name Cheating Couturier funding 03 And Hillary has it to minus turn. Bring things to They have so four with three minus tree, which is protesting Marcin. Very um Sonny Foreseen place to be. Arrest me. Oh, for with a 21 discharge. So long cylinder is to millions Andi stuffing and grooming use King B R oh, blurry.
