When acetic acid is treated with aqueous sodium bicarbonate, $\mathrm{CO}_{2}$ gas is evolved. The 'Carbon' of $\mathrm{CO}_{2}$ comes from (a) carboxyl group (b) methyl group (c) bicarbonate (d) both carboxyl group and bicarbonate

Congregate acid base pair identification, huh? All right, so we're given a list of contractor reaction equations in this case, for a we have in each three s h 20 an equilibrium with its products of NH four plus and O H mites. So remember, the definition for a conjugated acid based hair is just that they differ in los or gain of one hydrogen. Can I on So on Lee differ in the loss or gain of one hydrogen cat I own. So here we can point out the similarities. Hydroxide water has an h born in H three hydroxide differs from water in the loss of a hydrogen cat. I own well, NH four difference for ministry in the gain of hajj cat. So here we can make our acid conjugated with these players and h three and NH four plus no here water and hydroxide for be Our second reaction equation is peeled 43 minus plus water An equilibrium with products of H P 04 to minus. Plus I job site is in the same definition We can see similarly, the hydroxide and water differ only by the loss of a hygiene cat. I own well HP a four to minus and for three minus different by the gain of the Haijun cat, I am so once again those air congregate acid base pairs. We can just write them below CEO for three Mya's and H P 04 to minus second country aspects. Paris Water hydroxide For the final reaction equation, let me just partition these ellipse of trouble, drawing straight lines sometimes. And it was for the actual equation. See, we have C two h 30 to minus plus water an equilibrium with this product, its products H C two, h 302 and hydroxide. Once again, we see hydroxide water the president. Each one of these reaction equations differs only by the loss of hydrogen cat ion and H C two h 302 and see too extreme to differ by the gaining of hygiene. So once again, those air congregate acid base Paris the blue red and we can just write those out similarly to before So see Teoh h 302 I don't have a space there c two, h 302 and H R minus H C two h 302 and then for the second country acid base pair. It's water and hydroxide

In this question we have to write need our nic equation that each of the given species can act as a brown stayed. Lowry acid Bronstein Laurie Essid. Yes for town Donna. The first pieces here is hi dani um iron and we need reacts with water. It donates proton and then ionic equation is H plus and H. Two. The NATO ironic question is this one. Then the next diseases A CIA a saline aqua solution. Excellency, Branstad. Lowry acid by donating is proton. And the net ionic equation is each classic worse plus C. L minus. The next business is ammonia. When ammonia reacts sweet to attack, it donates his proton and becomes a niche to minors. And the needs are mickey question. Here is this one. The next pcc is acetic acid when it reacts with water. Uh It donuts a proton and produces stc W minus. And the need an icky question is this one. Mhm. Next one is and it's four plus This NH four plus. When you actually get water donations, proton and becomes in history. And the NATO ionic equation is this one, Then the last PCCHS 04 minus in a quick solution. Anita ionic equation for this one is glass sulfite.

All right. Today we're going to doing Chapter 16 section problem 12 from chemistry, The Central Science edition 14 but for home. So we're going to be entering what is the acid and base among the different reactions listed below. And if it is a Louise, are genius or Bronson Mari. So to be able to do this before saying is that definitions of deliveries are heinous or bombs and Mari and so do you that I have a little table here explaining what those acids and bases are considerably acid is an electron, except, er where bases electron donor. No, Hey, hey! Gnaeus is and the H plus an H +20 where the base is the old each minus in h two up on the Bronson Mari is the H plus Dermer, where the base is that each plus extractor. So for part a of this question, we're going pcl four plus CEO minus goes to P. C. L five automatically, we can, um Garrett of the art genius and Bronson Larry acids and bases for the fact that there's no high Shin's exchanging or any hydroxide groups and this equation. So, you know, those are not part of it. So you know that it is a really, um, acid and base, um, equation here. And also, we know that there's some type of election exchange happening in this process is well, And what's happening is that the PC all four is gaining the electrons from this chlorine and ion to create the PC. All five. And since PCL for is that the electron? Except, er it makes it the acid. And in the CIA and I on is the base for part B. I'm going to actually draw out the blue restructure and like a bone format just to show kind of what destruction looks like in to get better. You're going on about how the new molecule is being formed. Two people answer this question. And so we had the n H three over here with two lone electrons. Well, I love trump hair on top of the nitrogen plus B 8/2 3 and I goes to the nitrogen bonded to the bar on with very hard regions when Florian on the outside withdrawal. So what we know what's going on here is that the bond is happening between the nitrogen and boron, and so Therefore, there's no hydrogen is being exchanged here, and so therefore again, it's an electron donation happening here. And so therefore the ammonia is donating the left side in each series of joining the chance of Therefore, this is going to be the beefs. And since this is accepting the electron, it is the acid, and it is the Ritz acid and base. And for the last one for questions, see, we have a L each to oh six Teo three plus charge plus age too. Well goes to me well, each to oh, five your age to us plus h three plus. And so here What's happening is we are breaking down one of these water molecules and joining a hydrogen to this water, leaving us with an O. H and then in a church closet. JJ to over here. And so therefore, since we're donating a hydrogen to this h 20 we're having it broads and Larry. And since this is donating a hydrogen, this is going to be the acid, and this is going to be the basis that is accepted. Thank you for watching and have a great day

Sodium carbonate, sodium carbonate solution, sodium carbonate solution is alkaline, sodium carbonate solution, each alkaline due to due to sodium carbonate solution. Age alkaline due to high delicious of due to I do Licious of c 03 -7, 3 -7. So according to the option option B, each correct answer for this problem. I hope you understand the solution of this problem.
