In this question, we're going to be looking into the scalability of the given combat. That is we've been given incomplete game with our elections and we've been asked to look into the scalability and then we have to look into net. So before we answer this question, let's just look at this in terms of this variability in H2. So as a general guideline, Alcalay alcohol, um Eater of souls and I'm money, I'm sold. These are solid wood in water. Then the next guideline is most. Matrix also have asserted. We also have right. These are also sorry, book in H two. Then again we have silver let and Make your results. These are insoluble and H 20. And then we also have Gloria from my and I a rights that we know to be Soluble in H two. And then moving on, we know that most upon it. We're looking at a cup on it satisfied oxide, hydroxide, It is a these are generally insoluble in water except for maybe body. Um and calcium might look science that are slightly solid. And then finally we look at soffits. These are generally soluble in H. two or except for barium and calcium solve it that are not solely so looking at this information, this is what we are going to be using to predict the suitability of given compounds and the product. So for the first one we look at the first one, we can notice that those two reactions are in our curious form. So what is going to happen is the net the reaction that is going to be happening. It's more like a double replacement reaction. We were going to have ceo C. L toe plus into is from C E O. S Last two miles off so to employ. So looking at the products that we have been that has been formed. We have seen you as and certain employees. So here what we have is we have copper sulfide. This is a self right? So this one is in solid form. So this is going to be there solid. But looking at such time curate, this is an alcohol, a meter salt so this is soluble so it will be in solution. So the net ionic equation here this is going to be Let's just look at this. We have See you two plus we have two moles of chlorate. Irons. Remember ions are only formed by the species that are in our class form. They're looking at sodium we have two and a blast last we have the song for. And the products this is going to be copper sulfide which is a solid Plus two moles of sodium irons plus two moles off chloride iron. So to write the late ionic equation, we have to remove the spectator I am. And in this case these are the sodium irons and the Glory and they are Spectator islands because they are common. All found in both the reactions and the product. So the net ionic equation is going to be suffered. Irons in aqueous solution reacting with cooper two plus irons in anger solution to form air copper sulfide press a bit. So this is the general approach that we're going to be used. So if we look at the next one in the next one we've been given museum from my end potassium up on it. So if we do this, if we look at this, yeah MGB are two plus okay to see or three all of these are in our class form. What is going to perform here is museum cup on it plus two malls of K. P. up. So if we are to look at this information, this is a cup on it. Looking at the general guidelines that we had here completed to say in general components are in solid. So this is not going to be in our classroom, this is actually going to be a solid. And they're looking at K. P. R. This is an al curly metal soul, this is soluble so this is also going to be in solution so to form ions. These are the compounds that are we are going to be splitting and if we follow the same procedure that we followed above. First of all, break down these into irons and then remove the spectator irons we'll find that what is actually happening is we have mechanism irons reacting with upon it. Irons to form our magnesium upon it as a president And then moving on to the next one where we've been given BACL two plus a tool is all well. So if we look at this, the reaction this one, it forms B A S 04 plus K C. Yeah. So if we look at the scalability rules, remember these are in fact this form. So they do form irons. But if we look at the scalability holes we completed to say barium sulfate is not soluble, but this is an alkali metal sort. So this is so liberal, going to be an Arkia solution and this is going to be a solid. So again, if we split these compounds that are in Accra solution and remove the spectator ions, what is actually happening is barium to blast plus S +44 to minus ions in aqueous solution. These were performing but I am so fit precipitation. And then finally, if we look at the one the last one This time around, we've been given HG two or 3 that is in our class blast K C. L. That is also in actual solution. These are going to performing SG two Cl 2 blasts, KN 03. Again, this is an alcoholic meters or alcohol. E meters hold so this is soluble. But then looking at this, make everyone this is not going to be soluble. So this is going to pay our salt. So if we split these irons down all these compounds to form irons and then to move the spectator irons, what we're going to have is H G two plus plus to blow right irons desire Marcus for our HG two Cl 2 solid.
