Write balanced complete ionic and net ionic equations for each acid-base reaction.
a. HBr(aq) + NaOH(aq)
b. HF(aq) + NaOH(aq)
c. HC2H3O2(aq) + RbOH(aq)

So this question we have to write the complete energy person and also need energy person for each of these energy persons. Now for first there is uh the shapeless argue it. It will give to this water that is this true now the complete I only person and then it and it was first will understand what is complete on it and what is not an impression the complete and efficient is the equation in which all the answers. So that is it is it is the main it can be the main iron which of course in the equation or it can also be the speculator and that does not occur in the uh manifest. Now what is not an exhibition the net and education is there uh main reaction that those only the species that are involved in election. So we'll see here by example that is for HIV plus RV which now uh we can dissociate all these items into perspective. Uh that is X plus plus plus I minus for our viewers it will be argued R. P plus plus or minus then for R. B. A. This is forested so it will not necessary but what really associating to express support and what's happening now we can see that this is the complete any person, this is the complete any person and it shows all the Ionic species whether it be spectator events or or it will be the maintenance. Now what are the spectra Tryin spectator answer the irons that does not take part in the Net. So here we can see the spectator answer it's Plus. Irons and woods innocent because they're cancelling out here. They're cancelling out here because simply they are canceling up here. Yeah. Yeah that is it does not occur. Do not occur in the main reaction that is the net. And if so what is the need an exhibition. Whatever we cancel out whatever remains. Is that not A. R. B. Plus I minus gives are being. Mhm. Similarly for uh it's C. H. 02 plus any which gives uh sodium permit plus water. Now this is the pharmacy and sodium hydroxide. So we live it into the respective iron cities. The Foreign ministry dissociates into for former iron and X. Plus in a plus uh in which the dissociation to uh in a plus sign and which medicine similarly, it's good association to explosion always medicine but it will not disappear because it is a small ship. So this is the complete and and here this potato answer saying that this explosion watchman is So for the head and recognition simply we have to cancel out this explosive voice minus from both the sides together. Net and the person that will get us its ceo minus. That is a format. And plus in the present to give the sodium format. This is a white solid compound. No, for the last 100 days. Yeah it cannot be said that this season. So which is uh three or two plus lithium hydroxide gives uh let's see um a city plus water now for the complete an infusion will uh listen to each of those uh Each of these uh spaces into respective islands and uh solid now uh the eternal businesses into uh the city diane les uh expressive and lithium hydroxide difference uh disappears into lithium plus I am. And what Afghanistan the little necessary uh Syrian and will not uh this is because it is a solid and the water will necessary to express engagements. Now again you can see that the X plus and minus are cancelling out because they're also the spectator alliance that do not take part in the millions and that is they do not over there and equipment. Hence the remaining because it isn't it? And the question that is uh dan let's listen, listen gives uh listen kid this, he's the Ceo and uh yeah.

So we're given some chemical equations and we have to write down what the total Ionic and the Net ionic equations are. The nice thing is, they give us the initial equations, so it's going right down the 1st 1 here. We've got hydrochloric acid, and I'm going to spend a little bit of time here to write the phases because they are Preeti Important, plus sodium hydroxide yielding sodium chloride. And that's Equus. Generally, anything in Group One is going to be a curious plus water each toe liquid. So we have toe write down. What is the total Ionic equation? Well, remember, each of these acquiesced bits can be broken up into the cat ion and the anti on because that's physically what's happening in solution is the ah. So, for instance, you have the positively charged hydrogen, and then you have had the negatively charged chloride and those air physically separated in solution. They're not Ionic Lee bound to each other in solution because it's soluble. That's what a quickest means on. So I'm gonna physically write them as separated. So, uh, I'm gonna write them as H plus and I'm gonna go ahead and leave off the phases here just because it is Ah, a little bit much for every single one. But know that each of these is going to be a quickest plus chloride plus again. So sodium hydroxide is a Chris, so an A plus plus hydroxide is one unit. Those are bound to each other in solutions on the leave that sodium hydroxide are sorry. Sodium chloride. Hey, Chris is sodium cat ion and chloride and I on plus each to a liquid. It's not a curious it's bound co Vaillant Lee some believe it as liquid water. Okay, And then what you'll notice right is that some of these cancel out s O for instance, the sodium is cancel. The chlorine means cancel rather the chlorides cancel. And so to write my net Ionic, I'm just going to write the bit where everything has already canceled. So appear that's my total Ionic. And now my net Ionic, right When Ah, please, Blue Net Ionic. The things that don't cancel are the hydrogen, and I'm gonna go ahead and write it, uh, that it is a quist plus the hydroxide, which is also a creates recall forming liquid water. One thing I can check here is Is the equation balanced? It should still be balanced if it started out of this balanced. To begin with you're canceling. Shouldn't change anything. So it should still be balanced. And in this case it is. So we know we've done it right? So there's our total and net Ionic equations. All right, let's do another one. Ah, were given magnesium metal, uh, plus hydrochloric acid. Two moles of hydrochloric acid yields magnesium chloride. That's acquis. Plus hydrogen gas is evolved in this reaction. So again, let's write out the individual pieces bits that are acquis Arthuis, Ah, hydrochloric acid and the magnesium chloride. So I'm going to write them as separated, amused green for the total here. So magnesium metal plus two moles of H plus plus two moles of C l minus. Remember, So the two coefficient appear distributes to both of these yields magnesium chloride. So magnesium is two plus plus two chlorine, all each of one minus That way, the charges balance plus each to gas. Okay, so parts that cancel, Really, it's just the glory in In this case, that's the only thing that cancels. And so the net Ionic is going to be magnesium metal plus two moles of hydrogen cat ion, and that's dissolved in solution yields magnesium. Can I on also dissolved in solution plus hydrogen gas? So there is my net. Ionic. Okay, let's do the last one here. Last one. Ah, the equation is given to us as cadmium chloride, which is a quist plus sodium carbonate, also a Prius. It yields two moles of sodium chloride. That's also a curious Plus. I'm gonna write it on a slightly new line here. Cadmium carbonate. And that's a solid. Okay, so, bitch there, Equus, everything except the cadmium carbonate. I'm gonna write everything out. Eso we've got cadmium, which is a two plus. And if you can figure that out just by looking at the Ionic equation, are the chemical equation appear? Not really Equation, but the formula. Um So the ionic formula for cadmium chloride I have to Chlorine Z. I know each of them is a negative one. So to get the charges, surveillance cabinet must be a positive to charge. Then I have to chlorides. There are two sodium cat ions plus a carbonate, and I on I'm gonna write the products on a new lying here. I've got two moles of sodium cat ion, plus two moles of chloride and I on plus my final product, which is cadmium carbonate. And that's a solid right. So let's look for pieces that cancel. Well, the two chlorides cancel the two sodium is cancel on so that all that I'm left with for the net Ionic is going to be cadmium two plus and that is a quis plus carbonate Equus. That's two minus recall, uh, yields cadmium carbonate, and that is a that's gonna be a solid so that that is my total.

See the frustration Here we have. Jack was a city usage reacting with ek was burying my drug sign. So first you write down the porter's off this relation with you all day barium pass it in, which is also salute in water. And that's how it'll back wass and we'LL have water Now I have to balance this equation So is started the medal and we will make sure that we have same number of metal atoms in both sides It's our mental here is very um we have one Very, um here and one very m here. Then we'll have flu Funny non metals are any in a group off atoms which is acting as radical here. So if we have any group of Adam intact in both sides, then we can We don't need toe count each adams in it individually. Instead, we can count the total group of atoms as the one So here we have. The faceted group is intact in both side in that Mexican counted altogether. So you have two exited group here and we have one here that missy have tomato bread this side by two. Now we have to. So after balancing metals nor medals and group off atoms. We have to balance high treason. So now here we have two hundreds in here and we have two hundred and here saying totally have four hydrogen in this sign and in the product side we have quiet reason that Mr to multiply the product signed by two. We have four presents in the product side also. Now we have ah forehead reasons here and in total for hydrogen in the reactor site and finally had to balance oxygen. So we have two oxygen here and we have two oxygen here. That means oxygen is also ballast. So this is the balanced molecular equation for creation. Now we have to write down the total iron education of distillation if you want to write the NATO and immigration So in case of total and education we will write the compounds in their ionic form. If they're strong electrolyte or there'LL be strongly, strongly associated or completely dissociated into their irons. So, um since acid I guess it is a weak acid, it will not completely ionized air completely dissociated into exiles. That's why we will right as city Gacy in its molecular form then barium hydroxide being a strong base that miss it will be completely ionized related in the Ionic form. Now we have proof as it did here. Are you a citizen? And we will write the barium hydroxide in the ironic form and in the product we will have so bury a massive did will be completely ionized And that's way um, we'LL have tto write this as barium on and as it did on. And now we have to look for the spectator rounds are common ensemble sites and here we can see that we have Barry Amar in both side and you could cut them. And the rest is our NATO Donaghy creation safer. Just got this true from here the barrier miles from from both sides. Then the reaction we have or the question we have is basically to see three c w h plus to wish minus is equal to and oh, here we had our twitch tool ceases to his l'equipe to not pay It believes in the commuter molecule of form. So you're in the reactor site. We'LL have a prestigious in two hundred signing the product side We have ah two c's three serial miners and which tour? And if we just write them in if fresh equation here it will be to see through see, never age plus two is minus in a quiz form I didn't give us USC Tate plus Jewish tool Come. So here is our net an equation for this creation here. Then we will go to our next one where we have home solid chromium hydroxide is active with nitrous ascent So here our actually question always here always three since it is solid from your grated Sahlin and it is reacting with Nitra Assassin agent too, which is obviously Akwa since it's a soluble in water and in the product we have chromium nitrate class is too Now To balance this equation, we'LL have to balance the chromium Sze first was the metal So we have one chromium in his sight. Then we have to Ah, Bella's the nitrate group here, which is a group off Adam's. So we have one nitrate here treated right here that missing tomorrow, right? She's on my three now we have nitrate balanced. Now we have to go for high treason. So you have in the reactor and said we have three had risen and three hundred in total. Six had risen your dark side. We have glide risen. That was a modified with three to get six had risen on the product side also and now we have to balance the oxygen's. So we have three oxygen and six oxygen here, two times two Sikhs and plus three that ms In total, we have nine nine oxygen in the reactors side. In the product side, we have three times two Sikhs and three blustery That missed nine oxygen in there in the products that also So this's our balanced molecular equation for registration. Now I've read the total and education So chromium hydroxide being solid, it will remain a solid in the interrogation also. Then we have to go. So a genital being equals It will be ionized into its H plus And you know, to Mina san and in the broad out we don't have chromium. In this case, chromium nitrate is also Acas R is soluble in water. That's it'LL be remain as here Tripolis and three you know to minors and finally we have three water. Now we have to look for the common aisles and we have remove them from the equation tohave the NATO an equation. So the common and here is nitrate on, so only nitrogenous common. And if we just cut the nitrate ion, we can write the name Tiny question, which is see our wage. Treem will react to it three h plus to provide Sierra Tripolis and traced to him. So this is our net on education forthis reaction. Now we go for the last one where we have a quiz. Night creatures city neck was ammonia reacting. So AC wass nitric acid a Channel three classic wass ammonia will produce anything for Plus, Hank was and you know, three minus. Now, if you wantto balanced this equation, let's look for any medals here, so I don't have any metal here. Then we start with the non metal. So we have. We have nitrogen here, one nighters and here and one night wasn't here. And then we have one night trade group here. Oh, one nitrate group here and one nitric moving the product side else. Um and then we have four had risen in the reactor sign and four hundred on the parasite. So the reaction is already balanced you don't have to balance it. Now let's go for our total and education's a Channel three being strong electrolyte, it will be completely ionized. Let men still write it as H plus and they're not three minors and and one day I will be an ex Monica or farm on the port side. We have both already in the attic. From now here we look for a suspected Ryan or the common, and on both side of the question here we can see that nitrate down is common in both side. Then we can cut them right, our net on medication that will be h plus creating with finished treem to produce and if you four plus. So this is the net on education for destruction.
