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.
