Write balanced equations for each of the following by inserting the correct coefficients in the blanks:

(a) $_{-}\mathrm{Cu}\left(\mathrm{NO}_{3}\right)_{2}(a q)+_{-}\mathrm{KOH}(a q) \longrightarrow _{-}\mathrm{Cu}(\mathrm{OH}_{2}(s)+_{-}\mathrm{KNO}_{3}(a q)$

(b) $_{-}\mathrm {BCl}_{3}(g)+_{-}\mathrm{H}_{2} \mathrm{O}(l) \longrightarrow_{-}\mathrm{H}_{3} \mathrm{BO}_{3}(s)+_{-}\mathrm{HCl}(g)$

(c) $_{-} \mathrm{CaSiO}_{3}(s)+_{-} \mathrm{HF}(g) \longrightarrow$

$_{-}\mathrm{SiF}_{4}(g)+_{-}\mathrm{CaF}_{2}(s)+_{-}\mathrm{H}_{2} \mathrm{O}(l)$

(d) $_{-}(\mathrm{CN})_{2}(g)+_{-} \mathrm{H}_{2} \mathrm{O}(l) \longrightarrow_{-}\mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4}(a q)+_{-} \mathrm{NH}_{3}(g)$

a) $\mathrm{Cu}\left(\mathrm{NO}_{3}\right)_{2}(\mathrm{aq})+2 \mathrm{KOH}(\mathrm{aq}) \longrightarrow \mathrm{Cu}(\mathrm{OH})_{2}(\mathrm{s})+2 \mathrm{KNO}_{3}(\mathrm{aq})$

b) $\mathrm{BCl}_{3}(\mathrm{g})+3 \mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \longrightarrow 3 \mathrm{HCl}(\mathrm{g})+\mathrm{H}_{3} \mathrm{BO}_{3}(\mathrm{s})$

c) $\mathrm{CaSiO}_{3}(\mathrm{s})+6 \mathrm{HF}(\mathrm{g}) \longrightarrow \mathrm{SiF}_{4}(\mathrm{g})+\mathrm{CaF}_{2}(\mathrm{s})+3 \mathrm{H}_{2} \mathrm{O}(1)$

d) $(\mathrm{CN})_{2}(\mathrm{g})+4 \mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \rightarrow \mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4}(\mathrm{aq})+2 \mathrm{NH}_{3}(\mathrm{g})$

we have devised a camcorder reaction by adding the appropriate coefficient Is that the first week Asher will be jean corpora, um, nitrate and potassium hydroxide, a phone copper hydroxide and also some 93. So, the first and, um and I'm gonna choose the bonds will be the one that can only find in one of the reactor and also, you know, only one off the opponents. So, um, Cooper entry is a pretty good sign point. So I would just cooper. So on the left rear copper in a tree on the right, we have corporate hydroxide, and they are Boo bah. Yes. So they are the only people contain one copper, so we don't have to add any coefficient the second's visas have. Which shows would be the night tree iron? Um Ah. Along with, uh, with the copper nitrate, we have 2 99 So after and the Syrian fell off. Um, protests Sim nitric. You know, the bonds that All right, so Ah, oui. We move on. Um, we have to put a seven night trade. Right? So we must need to put some iron. So we also have the to put two infernal potassium hydroxide. You know, the thing about it is that the last one will be the hydro sign. So because we have to have your side and the right and the left, we have two potassium hydroxide, so it's already partners. Okay, move on. To be a question, be will be self flee reward er and every half I free be awfully without actually out so again which shows the enemy in that only a person game One of the species in the breath and sign and also only prices in one of the species in the palace eyes. I was just for him so that we appreciate BCL flea on the right. We have actually p 03 they all have one for, so I don't have to do any a bouncing at this moment. Okay, so for BC elf we we have flea CEO off the Korean off equal. Right? So the rate we have xy l. So we had to put a free, even exhale. You know, often of the other bands are the call Corinne. Okay, So, um, the Fuhrer and Corinna bottles we move on to look at 100 so but because hydrogen have ah you see hydrogen, you first. And you both, uh, way apart. It s so you're really complicated. You've reconsidered. Hydrogen be over. You have to rebel to thing about. So maybe it was Give hydrogen with oxygen. So for oxygen, we have Ah, from on the right, we have Ah! Ah, for a to B Be awfully we have if we ask the dream. So in the lab just put three and funnel h two. Also, we can bones the oxygen. All right, so, um, free eye watering bans. The last one we hydrogen song of right where? 83 Bill 40. And there were three inch the hour. So told it would be so. Sergeant, on the left, we have three water. So also is Soto six hydrogen. So this whole equation Spartans Okay, we'll move on to see again chose the one that only presents one of the patent and also want deposits. So for this case, I would Ah, you can stop Brickhouse him. You guys start thinking up to you. So for this, his I would starve if Ah, calcium. So on the left were C C s I ow! Free on the right way, CF sewage is everybody's, so we don't have to add the number. Okay? And then we'll fund to the USA Cam. So we have one seat left, and then we're s I F four on the right side also one second. So we don't have to, um um and lumber to bonds that. Okay, So how about oxygen? So, for oxygen, of leverage for you on the right, we have. Ah, we only find it in water. So we can about bands all singer by adding three even the water flowing in from the water. Okay, so we have all station bombings. We have, ah, scarcely most income bonds. But we still have hydrogen and foreign two rebounds. All right, so on the right, before we already FB Aah! Hodge to free of a large doors were 600. So where I would put us 16 fellow h 40. So I we have 600 slaves, rare bars, and thus but know this would be the forward. So we have our f four for foreign and two foreign Also be six. So we already have 16 for that extra half size over already Violence. Well, so that's reaction is we have a C and two plus water. We have to see too old for an angel. All right, So, um, let me be right. Uh, I'm gonna question other bids. Okay? So for the case again, I'm going to chose, um, the elements the only president game one of the reactor in species and also only a present in one of the point of species to start with. So from here, I think I can, um, start with nitrogen. So on the left, um, natural cabinets, you so under left, we were half. Ah. Which was kind of Nash in. We have to to see a So we have to see into and so nitrogen on the righteous. I'm only a and actually, So I have to put to ye informer. Actually, you know the bonds that and then we'll fund to cover. We have to see on the left from CNN to and also we have to stay on. The rice is already buying, so we don't have to put a number of fun off san too. And also, you know, h to see 204 Okay, so we have the nitrogen and ah cabin done so that lets when we will be Ah, we chose oxygen. The reason he said, I can be also the only present in this business and also in this business. But for hydrogen impressing in both, um, it's you a C two or four and also Ah, actually, they both pull it. That's why I was several surgeons. That so the rare air Force that you're not left. We have to perform from which to in order that bans the Austrian. Okay, the last one will be the Hodgins. So we have eight on the left, and then we have to pass six on the right. So we ate. So he's already bones. So here are the
