So we need one chromium to chlorine islands and one eye that, uh all right, so let's start, first of all by taking care of the gas parts, So chlorine is already a gas, so we'll need to go ahead and convert chromium and iodine to a gas. You know, each of the elements should be charged as an eye on, and we want the numbers of elements to match. So what? That means all the states of matter should be gases. All right, so know what our goal today is to make each of the islands on the left look like the islands on the right before they pass through kind of the lattice energy process. And again, that negative just means energy is being released rather than absorbed. Hence the energy of formation that they give us is negative. And then what we know about iodine is it's a little bit different because it's actually a solid at room temperature. Oh, since of course, E l, too will be a gas. Temperature state got zero to plus I to you. And so we're gonna arrive at the same result of CR seal to I, except in this case, we're going to start with con just the elements at their basic natural kind of room. No, on the other side, what we need to pencil in is what's called the energy of formation. This is X, since that's what we're solving for here. And that's the energy released when you take those gashes islands, inform them into the overall crystal at us for the compound. And so this is what we refer to as the lattice energy. All right, chromium three plus plus to Corrine one month's is plus an ID on one minus to make her overall compound CR seal to buy. And so what that means we're dealing with is we should have each of the ions kind of in their gas state, and at that point they're going to be converted into the solid compound overall. So what they're wanting us to solve for in this case is the lattice energy. All right, that among let's go ahead and start. And so that must mean that chromium is a positive three in this case, meaning that it has lost three electrons. Negative from the Koreans, one negative from the Ida, and that's a total of negative three. And so what that means for chromium if I have to. The problem is, let's make sure we know I told you those are kind of a sunny beach party, one minus. Now this compound is maybe a little bit unusual, and so, well, let's do before you begin. Our fun compound is CR seal to I, and that's in a solid state. And so let's go ahead and kind of make a boundary for are born haber cycle by drawing a line at the bottom and a line in the top. So here we have another born haber cycle, so I definitely want to make sure you have your calculator kind of happened ready because we will definitely redoing some calculations.
