All right. So for this question, we&#x27;re looking at which of the following compounds has more chromium. So first compound we&#x27;re looking at is 1.0 grams of chromium to chloride or C r C L to second compound 1.0 grams of chromium, three chloride or CR CEO three on the 3rd 11.0 grams of C r. See, I&#x27;m sorry. Chromium oxide from four oxide. Sorry at a c r 02 So chromium. There&#x27;s only one Adam of chromium in each of these compounds, so we need to look at the other elements that are attached in the quantities of those elements. So we&#x27;ve got to Corinne&#x27;s. Each chlorine weighs about 35.4 five grams per mole, and oxygen weighs about 15.999 brands promote. So it would take two oxygen atoms to equal, um, or come close to, equally rather the mass of one chlorine Adam and Gramps promote, so it looks like chromium four oxide is going toe weigh a lot less than the other two compounds the chromium chlorides. So that means that there will be a greater number of chromium for oxide molecules in one gram thin, the other ones for the same mass. And then, by extension, there will be a greater number of chromium Adams in that sample compared to the other ones for the same, so chromium four oxide will contain more chromium than the other for one grand.

So this question is about the right name and formulas off some compound. So for party that is CR or three. So this is known as chromium six oxide. Because here oxidation state of chrome amis les six because off oxygen is minus two. So we get this. So for Barbie, that is what I she um What? I she, um magnet, but I should mention it. So production magnet is nothing but production magnet. So this is the year toe. I am an awful So this is what I shall magnet apart. See, chromium carbon, That is chromium garbling. Goldman Cardboard, that is CIA seal six. Body of the question that is the a C R. Toe. 47 So this is an honest, very, um, like remit bid M day. Good on me for body that is Lenten. Um, so then numb three sell food. Lenten, um, three soul food. No, no hydrate. No, no, I would rate So this is our l. A s 04 Try start nine edge toe. So this is no, No. Hydrate is used for the nine water model and three is the oxidation. State off. Lengthen on inventing. Um three Lenton himself. So no part of off the ocean is That is you see entry 0.3 h 20 So this is no less gold. So in court three cyanide Are you hydrated? Pray I read. Go to three water molecule and observation straight off Golden plus three for this case. So this is our answer. So this is our so I books the answer. So this is what I am Magnate for third chromium Carbonell. So this is chromium Carbonell? No, Forties billion Dyke Remit. So this is very, um die plummet. Next, lengthen. Um Morneau Hydrate Lenton. Um three. Some perfect Lenten amply sulfites. No nitrates. Next. Is he called, please Cyanide right here today. So I read the answer in the green box for these formulas.

Mary Shields · Answer

all right. We look at the oxidation number of chromium in each of these compounds that we have to just consider our oxidation rules. So oxidation numbers for any element in its natural state on will be zero. So are chromium solid here, down the bottom has an oxidation number of zero. Okay, any element that has a charge Orion has a charge. I will have an oxidation number equal to its charge. So the chromium ion with plus three charge has an oxidation number of plus three now for our compounds. Um, all compounds have to equal zero if they&#x27;re neutral or equal the charge if they have a charge. So we know that oxygen has an oxidation number of negative too. So oxygen is negative too. In this compound is neutral, which means the chromium there would have to be positive too. Eso oxygen&#x27;s negative to chromium is positive too, which makes the compound neutral. Which leaves us with C r. 04 with a negative to charge. Now in this compound oxygen again. It&#x27;s negative too. And there are four of them. Right? So we&#x27;re trying to figure out what the chromium miss, right? You know, the Oxygen&#x27;s as a whole will equal negative eight. And the entire compound or Alan has a charge of negative too. So if we look at this in terms of algebra, if we add the eight to the other side to get the chromium by itself, negative two plus a means they are chromium here is gonna be a positive six. So our CR 04 with a negative to charge is gonna have the highest oxidation prefer from you.

this question wants us to determine which of the listed compounds has the largest number of ions. And before we answer this question, notice that all compounds except beryllium chloride and magnesium chloride contained two ions per molecule. But beryllium chloride and magnesium chloride both contained three ions per molecule of compound as all compounds way one gram, the smaller the molecular mess of the compound, the greater the number of moles of each iron present. And after determining the molar mass of each compound, which we can buy just summing the weights of all of the atoms which make up the compound. Um, while brilliant chloride and, um, calcium sulphate have our calcium sulphide have similar molar masses, there are a greater number of ions per molecule with brilliant chloride. Um, so therefore, brilliant chloride has the largest number of ions

Joanna Josey · Answer

so were given five different compounds. And we&#x27;re being asked to figure out figure out which one would have the largest number of ions if we had one gram of all of these compounds. So first thing we want to do is figure out the molar mass for each one of these. So going, starting with the 1st 1 b e c. L. Two. Um, that is gonna be for beryllium as 1.12 plus to plus two times 35.45 which gives a molar mass of 79.912 grams and censuses and ionic compound. And there&#x27;s two different ions. Um, work. You can go one gram of this times one mole is 79.912 grams. Times are big Odgers number 6.22 times 10 to the 23rd um, molecules her mole and then multiply that by they&#x27;re being three ions her molecule. And the reason it&#x27;s three is because one this breaks apart is gonna break into B E two plus and CEO uh, one minus CEO, one minus. So you&#x27;re gonna get to Corinne&#x27;s to chlorine I owns. So there&#x27;s three ions total. And this gives us a value of 2.26 times ton to the 22nd ions in that one gram. Hi. I&#x27;m we&#x27;re going to do the same thing for, um, magnesium chloride here. So first we find the molar mass, which is going to be 24.31 plus two times 35.45 which gives us a Moeller mass of 95.21 grams. Again, we&#x27;re gonna do some store ikeyama tree here. We&#x27;re starting with one gram times one more, divided by R, 95.21 grams times of a god rose number 23rd molecules. That looks terrible. More cules her mole times again. This one is also gonna have three ions per mole. Um, and that gives us a value of 1.90 times 10 to the 22nd I owns. Next one is calcium sulphide. So for calcium sulfide, we&#x27;re going to have 40 point 0/8 plus 32.7 which gives a similar mass of 72.15 grams. Hey, guys, start one gram. One mole over 72.15 times 6.22 times 10 to the 23rd molecules per mole. Now this one is really gonna have to ions her molecule. And that gives us a value of 1.70 times 10 to the 20 seconds I owns. Okay, next one, we have a strong Thiam carbon int. So this is going to be 87.62 plus 12.1 plus three times 16 for a value of 1 47.63 grams per mole. The one gram times one mole divided by 1 47.63 times have a Dodgers number more times. Again. This is a poly atomic, so it&#x27;s going to stay together, so we&#x27;re only gonna have two ions per molecule, so that gives us a value of 8.16 times 10 to the 21st ions that our last one here, um, bury himself eight. So we have barium has won 37.3 plus 32 point of seven plus four times 16 equals to 33.37 grams. We have our one gram times one mole divided by 2 33 0.37 times of a gardener&#x27;s number times again, Paulie Atomic says it&#x27;s only gonna break into two ions her molecule, and we get a value of 5.16 times 10 to the 21st. And then we can just look at all of our values and see which one is the largest. And as it turns out, the largest number is going to be for our beryllium chloride. The six point are 2.26 times 10 to the 22nd is the largest of those values, so beryllium chloride is the answer to that question.
