A sample of 7.75 g of $\mathrm{Mg}(\mathrm{OH})_{2}$ is added to 25.0 $\mathrm{mL}$ of 0.200 $\mathrm{M} \mathrm{HNO}_{3}$ . (a) Write the chemical equation for the reaction that occurs. (b) Which is the limiting reactant in the reaction? (c) How many moles of $\mathrm{Mg}(\mathrm{OH})_{2}, \mathrm{HNO}_{3},$ and $\mathrm{Mg}\left(\mathrm{NO}_{3}\right)_{2}$ are present after the reaction is complete?

Hello. Today will be doing product for six. Um similar pollen to number 45. So no huge difference. So if you remember from previous video 1 80 M Is equal to 760. Mhm Murphy. Okay. So if we do sending one want, hey Berkeley. Mhm. Divided by somehow. I'm 60 18. Very quickly. 0.0 945 18. Now we're going to substitute onto the osmotic pressure. Yeah, we went your formula. Yeah. You put this number. Uh huh. Mhm. Yeah. Let me sure. I'm sorry. Mhm. Yes. Cancer newscaster. Mhm mm. Yeah, I am a 0-0.00 39 Your mom later. So now we're going to calculate the most of this. Are you a catholic? So we're gonna take mhm. This number. Mm Okay. Mhm. Mhm. Times. Okay. Zero point mm. Mhm. Yeah. Yeah. Yeah. 50 The use is equal to 0.0 0136. Small. Now that you know, you're going to calculate them all maps. So and equals mass. Mhm. The vibe I moral mass m equals 0.250 grams too. Bye bye. Yeah. Yeah. Mhm. Your point zero is you one six. Well, I'm sorry. I meant to say you're going to calculate more mass. So when you rearrange your formula, I should be dead. So this is mass and this is mall. And the answer you should have gotten is 183 point ate clams over a month. Mhm. So that's the more mass And the answer to # 46. Okay, that's it for this video.

Okay here we are dealing with the neutralization reaction of magnesium hydroxide with nitric acid. Okay, so we know that visualizations produce water and salt. So the following salt will be a magnesium nitrate. Okay, so with that we balance. So as you can see here there are two nitrates will put on a two there. So now we see. Okay, we have four hydrogen to oxygen. So two moles of water. Now, first event, the limiting reagent 25 moles of each free agency. Which one is less? It's of the mass of this is a solid. This is a quiz liquid and acquis. So its mass 5.53 grands and it's moller mass is 58.32 g per mole. Okay, so if we do mass over molar mass, we get most of magnesium hydroxide to be 0.9 for eight months. Okay, so since we see the moles of magnesium hydroxide and of the nitric acid are 1 to 2. In order for the magnesium hydroxide to completely react, it will actually need double the amount of this. So that would be around zero point 18 eight and continuing. So let's see how much how many moles of nitric acid we actually have. So if the volume is 0.25 liters and its concentration is 0.2 moles, okay, we simply do the multiplication and we'll get number of most 0.55 months. Okay, So since this is much, much less than the magnesium hydroxide and we were expecting it to be double at least we can see here that the nitric acid is the limiting reagent. So against the explanation, there should actually be this should have been the molar mass or the number of moles of the asset for magnesium hydroxide to be the limiting came all interviewers times too. Since there are no 1 to 2 ratio and says it's far less. We can tell that it's the acid that will be limiting this reaction. Okay, so once the reaction is complete, they started lying means after. Okay. Since the since the acid is the limiting will assume that it goes straight to zero. Okay. So let's just copy that H N 03 will produce magnesium nitrate with magnesium hydroxide. Okay, so since it's in a 1 to 2 to one ratio, that means you have to have it's smaller amount. Okay. So we used a 0.5 miles first basically completely use it here in the proper ratio. We must divide that by two to get malls of the magnesium nitrate is being zero point 00 to five months. Okay, So then this one would have been 0.25 miles. But we have to use that to subtract. Okay, so it has been a minus that amount. And what we get here is, so your point is 0923 moles of magnesium hydroxide will still be left over, so we'll still have a bunch of this in solution, but no more as the acid would have been fully consumed.

Hi everyone. So in this question there's calculate the number of moles and the mass of the salute in each of the following solution. A two liter operating 20.5 molar sts of Arkansas, Senator sulphuric acid. So a part hear me is equal to, yeah, mandarin. There is equal to 18.5 into And that is equal to 37 balls off. It's to his so forth. Okay? Yeah. 37 moles of H. D. A. So called B. The N. Is equal to young women to be and that is equal to yeah. Yeah, 3.8-10 minutes to my list for you and 2.190s equally too, we find being In 210 nation -6 Small south a museum and that's Yeah. Then Sea park see bike. Yeah. An easy call to young and gov. And that is equally Yeah, 13 14, 3 into 5.5 And that is equal to 73.15 moles vaults. Oh, and see that's a ball bag depart. U. N. Is equal to m intervene And that is required to 1.8 in two weeks Condition to -6 into a point 3-5. That is equal to for you find it for you. Him too Damage to -7 molds of a fear. So for Mhm. Uh huh. FES 04 when myself salute? Yes. Yes. Moss Oh, salute. Yeah. A W is equal to men into young and that is equal to 37 into 98. And that is equal to 3626 Grand. Then be fart the police equality and into Yemen. And that is equal to 3.8 In to tenders to -6 into 14 9 zero. See the sign too, that is equal to 186.22 in two, National -6. Oh Graham. And that is equal 1.86-2 into unless to minus for grandma in a museum. Mhm. Yeah. Yes. Let me see it then. Next sea park wc culture and into um That is equal to 73.15 to 30 yeah. 031. That is equal to 2196.767 g. That is equal to 2.2. Get program off uh and sausage. Mhm. Then depart. W is equally true. Yeah. I mean too young and the basic want of 5.8. Fire into 10 to -7 into 1 51 point 908 That is equal to people. It find 662 into one dish to -7. And that is equal to eight 88 662 Mm. Hmm. Mhm. Yeah. Yeah. Mhm. Eight point it eight 662 in to tenders to minus for you grants of a fierce of more. Thanks a lot

So for part A we're going to be looking at the correct concentrations out of all the correct doses are sorry, the correct concentration Out of all the labels that we have, so we have 11 that are correct. And then in the concentration labels we have our 11 plus the three that we got wrong, which is gonna be a total. So this makes us our probability of 78.6%. Now for part B, we're gonna be looking at the ratio labels we got correct So all that's uhh this part beat. We got our correct labels here from the ratios and then we got the 12 that we got wrong and the ones that we're looking at are the ones we got right. So that's gonna be our favorable outcomes too. And the total number of racial labels there are it's gonna be too Plus The 12 We got wrong. This is going to result in a probability of 14.3%. Okay. And finally, for part C Were asked to say which one is better. Um In my opinion, That will not really my opinion, what the stats show is that 78.6% of labels that are concentrations are accurate And only 14.3% of racial labels are accurate. So what we can include is that concentration labels are more accurate than racial labels. And that will wrap up our problem
