Hello everyone. Today, we have the following problem. What is the chemical formula for the following co ordination complex? Di Chloro bis ethen ethylene diamine, chromium three chloride. So let's break down the name. We have Di Chloro, the prefix diamine two indicating the presence of two chlorine ligands. So we have two chlorine ligands, we have biz which indicates two. And then we have the ligand ethylene diamine, which is often abbreviated as IAN. This lets us know that this ligand is present twice. It is a bate ligand, meaning it can attach the central metal atom at two different sites. And then lastly, we have our chromium three and this indicates that the metal center is chromium. We're gonna go, we're going to give it a three plus charge. And then of course, we have our Chloro which is negative one charge. And so if we were to put this together, we would have the following, we would have our one chromium, we would have our two chlorine leggings followed by our etheline diamine twice. And so we have to determine the charge. So to find out the complex ion charge, we make note of the positive three charge from our chromium three, we add that to the negative charge of our chlorine and we have two of them. So we have two multiplied by negative one. And so that is essentially positive three minus two, which is a positive one. So this is a positive one charge to make the overall charge neutral. We need one complex ion needed for a single chloride counter ion. So we had our chloric chloride ion is negative one, which essentially makes this neutral. And so if we were to analyze our and choices, we would see that Ancho B best reflects our response. And so with that, we have solved the problem overall, I hope this helped. And until next time.
