business Question three from Chapter 11 Section three And it&#x27;s all about writing a lab report for Boyle&#x27;s law. So Boyle&#x27;s law is pressure times. Brilliant. This sequel to K or a constant or pressure is equal to the constant times run over rolling for the inverse of role Yah. Okay, so Boyle&#x27;s law demonstrates the inverse relationship between volume and pressure. So the lab wanted you to craft pressure and the inverse eh? Volume. I see what that looks like on the graph. So we&#x27;re going to draw a graph. So on the x axis, we&#x27;re gonna have the inverse of volume said one over V in no leaders and and why Access would have pressure and that is gonna be in pounds over inches squared. Okay, so we know that pressure and volume are inverse relationship. So if pressure was decreasing, Bollywood increase or pressure&#x27;s increasing volume will decrease. But since the X axis is asking for the inverse of all Hume, this is actually going to have a direct relationship to the line is gonna be a straight line. So what were you doing this? Sometimes you get a lab report. There are some experimental errors that can happen. So when you&#x27;re looking on this lab report, you can&#x27;t expect maybe some human error or airs by random chance.

If you have a wan that you&#x27;ve rubbed on a surface, a cloth or something, you&#x27;ll find that there is a transfer of charges, so the one will have a lot of negatives and some positive charges. If it comes into contact with a substance like water, which is a polar molecule, we have positive and negative ends. There will be an attraction between the positive charges and the negative charges between the wand and the molecule. If you have a liquid on a piece of wax paper, Ah, this will say, is water. Um, water has hydrogen bonding between the hydrogen and the oxygen, so a water molecule is highly attracted to itself and will beat up. We call this cohesion other liquids, but do not have such a strong ah sense of intra molecular forces will not beat up. They will just flatten out on the wax paper, something like alcohol well spread out flat.

So if you&#x27;re trying to figure out, uh, which of these compounds is the best ants acid. And But when I say that, I mean, which of these neutralizes the most the most assets. So you may have heard the word antacid in medicine, right? So if your stomach you have a stomachache, um, your stomach acid could be too acidic, and you have to use an antacid to reduce the acidity in your stomach. Um, so in terms of an experiment that we could we could figure out which one neutralizes the most asset. Um, these these processes air called patricians, actually, and I&#x27;m not sure if you&#x27;ve warned about these before, but Trey Shins is When you add a specific, you slowly add a specific volume of strong acid two to any type of base, right? So all of these air bases, these were all fairly basic. Um, and you can track thehe mount of, um, acid. You add by using a piece of glass way that&#x27;s known as a pure ET. So these Bure ets our long, thin piece of glassware with a little funnel here, not a funnel. They&#x27;re called stock Cox. Right? So what you do is this Works like a graduated cylinder, so you would fill this up to a certain volume. All right, You fill this up to a certain I didn&#x27;t want to do that, Phyllis. So to a certain volume, and then you would have your ass ed or your aunt acid in the beaker. You&#x27;d make a solution. Unknown amount, unknown mass of your antacid. You&#x27;d have to use the same number of moles of each of these Thio. Be able to relate one of them to the other after each experiment. Right. And what you would do is you would drop Ah, slowly drop the acid into the solution of antacid. Um, until you see a peach Ah, pH change. Right, So you can use, uh, ph strips. It&#x27;s determined when the pH will change, right? So at some point, you have to kind of gauge. I&#x27;ve consumed all off the base with the acid because my pH changes from ah high pH as in very basic to a lower pH. So suggesting that all of your asset has fully reacted with all of the base. So in terms of what byproducts conformed, you have to kind of think about each different material you&#x27;re using here, right? So if you add acid to these, um, you might form a gas, you might form carbon dioxide. Right. Um, so if you see bubbling coming out of your reaction after the addition of some drops of acid, you might be ableto predict that co two, um, is being released in the reaction. Um, if you are over time, if you&#x27;re making some kind of an insoluble solid right. So if a solid starts to crash out of your solution, you may be able to use the suitability rules that you&#x27;ve learned in this textbook to figure out. Um, what? Ah, but by products are being formed, right? So you know that ah, lot of carbonates and a lot of oxides are not soluble in water. Um, so you could start to use a piece together. Some of the things you&#x27;ve read about in this textbook, as in terms of scalability information in terms of the different types of chemical reactions, there are what happens when you add acids and bases together. Um, so you could start to piece together all the things you learn in this chapter to come up with an experiment that I have kind of described to you here to figure out which one of these compounds is able to react with the most amount of acid. Um

this is Chapter 18 Question 54. So we&#x27;re looking to titrate cesium hydroxide. So C S O h with, ah, nitric acid. So with a chain or three. So the first thing I&#x27;d do is figure out the equations. So the first equation that we have here is the general neutralization equation. Sweet season hydroxide plus nitric acid goes to cesium nitrate plus water. Now, if we were to break this up farther, we would see that we&#x27;ve got cesium plus plus hydroxide plus a proton plus, I know three minus. And that would go to the water is liquid. This is a quiz. So this is broken off. So it&#x27;s using plus plus a nitrate ion plus water thes cancel with ease. So then that I&#x27;m a Caucasian here is just a TSH plus plus o H minus goes to water. And the way that you would actually perform this experiment is you would have some amount, some known volume of cesium hydroxide in ah flask. And then you would have a bureaucrat of, um we&#x27;re gonna start this trying over on another page, you would have a flask, and then from there you would have a bureau coming into it and at the bottom. Here, you have a stop cock summer and you would just drip nitric acid in. You&#x27;re seizing hydroxide until the indicator change color.

Okay. So question 54 it&#x27;s giving you four chemical reactions and asks you to design experiments to calculate the percent yield of the reaction. Um, and then ah, wants you to do the chemistry. Um, So, um, I think thinking about the experimental piece of this is probably more important than actually doing their reaction. Some of these were kind of they look more complicated. They look less complicated on paper than they actually are. But all kind of talk about how I would think about recording percent yield for these. Um right. So this first reaction is talking about reacting zinc metal with hydrochloric acid. Um, and basically, when I think about how you would calculate the percent yield for this experimentally, you have to really look at the phases of the products. What phase? Um, what is your chemical reaction in? So in all of these were gonna be in water. Um, and then what are we making it? How do we extract that? Right. So in this case, assuming you have perfect, strictly amateur here, right? You don&#x27;t have any leftovers, Inc Metal. Um, and the reaction is perfect. Meaning you only make these two products. Um, you&#x27;re gonna have zinc chloride in water and hydrate gas. Um, for that reason, I I if you guys were to do this, this chemistry, it probably would be in a fume hood, but hydra guesses explosive. Um, so I would just recommend skipping this one all together for the sake of your safety, but, um right, So, gases, if you haven&#x27;t open container, they&#x27;re really chewy. As you can do this, you can measure this in corridor. You committed the hydrogen gas, and they do make apparatus. Is that, um you can perform a chemical reaction and then in some vessel, um, and then the vest would have be a closed system like this. And then the vessel would either inflate a balloon that you could then make into a sphere and measure the radius to get the area and then use the density of hydrogen gas toe arrive at how many moles of hygiene in the balloon. Um, but that&#x27;s prone to a lot of error. But also, um, you&#x27;re gonna lose a lot of gas to the head space in the container. Um, and really up to where that sphere starts, you&#x27;re gonna lose a lot of your gas, but in your measurement process, Um, because the gasses expand and fill the volume of the container so it won&#x27;t all just go up into the balloon. I think the easier way to do this is probably the measures in chloride. So you&#x27;re in water. Um, all your other product is essentially gonna leave the vessel right in the front of gas. So if you have an open container, it&#x27;s gonna leave. And I would think is all you would have to do is then, um, as long as you weigh your beaker, why is that so thick? Um, as long as you weigh your beaker, um, you can just boil the water, um, and dry the zinc chloride and then weigh the beaker again. If you&#x27;re the mass of the free beaker, and then you know the mass of the beaker with the droids in chloride, you can get the weight of your product That way. The second reaction is decomp is decomposing sodium bicarbonate Ah, in tow. Ah, sodium carbonate water and go to write. So you&#x27;ll notice that the other two phases, just like in the first problem. The first part of this problem. They&#x27;re both gases. Even this kind of goes like an s. Um, she was too busy gas. Um, so that means that this reaction is being heated. Generally, that&#x27;s the triangle means, um, generally above 100 degrees is needed to get water to be a gas. So this is probably above 100 Celsius. Um and ah, you have a solid and your heating a solid, and it&#x27;s in It&#x27;s evolving gases. So something you could do is just have a Petri dish are, um, away boat or that by melt, but some kind of glass. You could even do this in the beaker and just heat the beaker. Um, and so for a long time, pretty much until you know, um, that the all the water and gas that can evolve will evolve. And then you could just way the sodium bicarbonate again. You could even track the mass of this solid over time to show how co two and high and the water vapor is leaving the system to arrive at sodium carbonate. Um, so I would say the best way to do this is the way the sodium carbonate after heating, um, you know, um I even sure how long this would take. Maybe a day we&#x27;ve in the back of the classroom. Um um after heat. All right. Okay. Um, this one&#x27;s pretty easy. Right? So you have a mixture of salt is the double replacement reaction. So sodium, sodium chloride Sorry, sodium calcium chloride and sodium carbonate are both some acquiesced dissolved in water. And you&#x27;re making something that is solid. Does not dissolve in water, sodium carbonate. Um, and then you&#x27;re making salt as a byproduct will stay dissolved in water. So the easiest thing to do here is just a filter. So they make vacuum filtration systems where you can recover your calcium carbonate on some kind of a filter on paper, and then all the water will go through, um, so that water that goes through into some glassware that&#x27;s being sucked down by vacuum is gonna be containing your sodium chloride. It&#x27;s you essentially remove all of your byproducts, and then you can wash and dry the calcium carbonate through heating on. Then, um, measure it that way, measure the weight of the calcium carbonate that way to get your yield. And then finally, similarly to the first question And the second question, Um, just thinking about what your byproducts are in these in these reactions and how you would remove the water that&#x27;s here in this acid base reaction to make sodium chloride, which is soluble in water and then water is a by product. So you&#x27;re in water because these air acquia solutions of acid and base and then you&#x27;re making water as a byproduct. So as long as you&#x27;re struck, Yama Tree is right for these reactions here, and you don&#x27;t have any leftover sodium club sodium hydroxide. Um, it&#x27;s probably better toe have excess sodium excess tad axis of hydrochloric acid because when you boil the water to recover the sodium chloride HCL, if you have any of that left over once, all the water has gone well, actually evaporate. Hcls is normally a gas when it&#x27;s not in a quick solution. Um, so that&#x27;s easier to remove than sodium hydroxide, which is actually also a solid at room temperature. Um, that&#x27;ll throw off your yield a little bit, um, so if he uses where do this is just a boil and ah wei the sodium chloride after drying? Um, this was probably one of the more safe ones to dio really B, c and D or more safe than a is. Um so if you feel like trying any of these, they&#x27;re not too difficult. Um, go for it.
