Write and balance each of the following equations, and then identify each by type.
a. copper + chlorine $\longrightarrow$ copper (II) chloride
b. calcium chlorate $\longrightarrow$
calcium chloride $+$ oxygen
c. lithium + water $\longrightarrow$
lithium hydroxide + hydrogen
d. lead(I) carbonate $\longrightarrow$
lead(II) oxide $+$ carbon dioxide

The balance equations. We need to make sure that we have the same number of Adam's on both sides, the reactant on the product side of the equation. To do this, we can only change what it called the coefficients, or multipliers that come in front of each substance. Never change the sub scripts or the numbers below, because that would change what the reaction is occurring with. So we look at which Adams were present on both sides of the equation. In the first equation, we have calcium and bro me. On the reactant side, there's one calcium, and this sub script indicate that they're too bro means on the product side. There is also one calcium and to bro means so this equation is already balanced has written, and we can leave it the way it is. See a plus B R. Two make C A B R. Two or if it helps you, you can also put the coefficient one in front of each one. But typically, if the coefficient is one, we leave it off so the balanced equation is see a plus B R to makes see a B R to our second example. P four plus 02 makes P for 0 10 The two elements present our phosphorus, or P, and oxygen. On the reactant side, there are four phosphorus and to oxygen's on the product side. They're also for phosphorus, but 10 oxygen's. So that means that we have to multiply the oxygen by a coefficient of five, which now gives us 10 oxygen's on both sides. So the correct balanced equation is P for because there's one of those plus 5 +02 makes p for 0 10 fared. Equation has the elements SB can Timoney S, H and seal or chlorine On the reactant side before balancing. There are two s bees. Three ass is one H and one quarry. On the product side, there's only one SB. There are three Corinne's two hydrogen and one sulfur. So to balance, we might start thinking, Well, I have two on this side, so I need to hear and so I can do that with my antimony ease. But remember, that also multiplies the chlorine by two. So now I have six Koreans on this side, and to antimony is on this side for sulphur. I have three here, but only one here, So I'm gonna put a three here, which multiplies the suffers by three but also multiplies the hydrogen is by three. So now I have six. Hydrogen is in six. Chlorine is on this side, but only one here. If we put a six in front of the HCL, that then balances the equation. And finally, for the last equation, F e two plus o three f E 203 plus C makes F E plus CEO. They have iron and oxygen and carbon on the set. I have two irons, three oxygen's and one carbon. On the product side, I have one iron, one kurban and one oxygen, so it looks like the oxygen's air not balanced on the irons or not balanced. So we'll start with the three here on this side. I'll put a three in front of the CEO, which multiplies both my carbon and my oxygen by three to balance my irons That can put it to here and then finally, to balance the carbon on this side. I can put a three here, so the correct balance equation is F e 203 plus three c makes two f e plus three CEO

I look question is read the balanced chemical equation of the following reactions. So we are going to discuss how can we read the balanced chemical equation of the given reactions in the question. So, first to be held unbalanced chemical equation that is well bye. Less oxygen gives this one. Okay now we have to balance this chemical equation. This we have to know that in the balanced chemical equation all the number of atoms in right side and left side must be seen. And here we can also observe that In the website for mobile and in the right site for provide is presented to into 24. In the left side six oxygen is present And in the right side six oxygen 3 and two. This present that means this chemical equation is balanced chemical equation. Okay, now I am writing all the unbalanced chemical equation to the balanced chemical equation directly. So the parties L. I. C. L. O. P. Be composed. Who allies here. Lastly you in C. Part see you plus Edgy Street to street. Uh huh gifts. See you plus two agents in the heart, BB and modrica Hall. Right? Plus two. L. gives PVC L two last two ally And with three. Okay, in a bar that's too slow food most here. What one trace gives a hoot As for food entrees feels it's true. Okay, These are the balanced chemical equation.

When balancing chemical reactions, there are a few simple rules that you can follow that may be helpful. One is leaving oxygen's till the end and another is leaving any element that is left by itself until the end and the last is Don't be afraid of fractions fractions often save you from having to start all over again. So let's start with this one. We've got to Seoul furs. So let's put uh to here. So now we have to sell furs that gave us to calcium size. We have two calcium, we have a total of 12 34 hydrogen. So we need to put it to there. So we have four hydrogen is that then gave us to oxygen's and we have two oxygen. So it's balanced the next one. We've got two or 3 hydrogen and two hydrogen. So the only way to make balance these is to use a fraction right up front or just recognize that if I multiply this by three, I'll get six, which will allow me to multiply this by two, which will give me six. That gave me two nitrogen. So we'll put it to their Now let's look at our oxygen's, we've got 12345 oxygen's. We've got to oxygen's. So if we multiply by 5/2 we will have five oxygen's. But then we get rid of the fraction by multiplying everything through by two and now it's balanced. And for the next one, this is what we have. Let's start by balancing the irons. We've got to iron. So let's put it to their so now we have two irons that gave us six chlorine. So let's put a six here. So we now have six chlorine, is that gave us six sodium. So let's put a three there. So we now have six sodium and then that gave us three carbonates and we have three carbonates, so it's balanced and the next one is a little challenging. Even though it looks relatively simple, we've got two irons. So let's put it to their, That then gave us four suffers. So let's put a four right there. Now let's look at oxygen's, we've got eight and three, that's 11, We've got to here, so we've got to do 11/2. They will multiply everything through by two and it's balanced.

My argument. So in this question, you have to balance the questions. So first immigration is a sisal Ford, Lakeville, plus M. D s gives a silicon solid. Plus, um, this here you do solid. No, the balance situation is okay. Balance. The situation is now, if you see properly, there are four chlorine and left hand side. But there is only one chlorine, so they only to chlorine side right hand side. So you're the first balance of chlorine. So for that purpose, right, The balance skeleton equation. Yeah. The s gives silicon s plus and see if we are to solid. So there are two floating side, uh, already aside and foreclosing side left hand side. So what you have to do is multiply this and visual by. He'll get four clean. Now, there are two magnesium at a reaches. So multiplied this magnificent by two. Okay, so, uh, we'll find one silicon. One silicon for chlorine. Four chlorine to EMC, two EMC. So the question is balance, then second one is and August Yes, plus cl two guys. Okay, guys gives and oocl guys. No, c l guess now the balance situation is the balance equation is is so first of all right, the skeletal equation. So no guys, Plus, we'll do guys gives a no sale guys novel, You know, uh, in this case, there are two chlorine at alleges, but one chlorine at our ages. So multiply this a notional by two. So chlorine sar balance now. Night oceans, They're not balanced. So multiple. You know, there are two nitrogen i directions, but only one nitrogen intelligence to multiply this by. So there are two night ocean at religious and villages to chlorine at Alexis and villages now see the option, whether their balance or not. So there are two auction. It alleges Hezbollah's marriages. And this The question is balance equation. It is balance, then. Next, see question Amino to Selene. Plus leaving him solid gills. And then Selene plus l two or three solid. No, Uh, you know, the balance situation is the balance equation is as follows follows. So for that purpose, you're right. The skeleton equation. 90 days, um n or two. Selene. Bless ls yes. Amen. As less l two or three sodded. Okay. Now, if you see properly, there are two aluminum at riches and only one I live in the middle Ages. So I live in, um items are non violence. Similarly, there are two options at LHs, but there are three. Auction item at Rh is supposed to balance the oxygen, so multiply. Uh, you know this at the right hand side by two. Elder three. And I slept inside by three to amend or book. Okay, So that auction items are balance. One option once auction items are balance, uh, will go for manganese item. So my goodness, item at alleges are three, but, uh, reaches only one so multiple like this, minus by then. Aluminum item 2 to 3 or four directors and only one at alleges. So multiple like this are living in by four. So three manganese on each side for alimony are on each side. Then three twos are six or six option items on both the sides. Then next one is okay. Do you want cr as plus a set? Salil gills cr two extreme solid. Now the balance situation is yeah, we need balanced. Mhm. Yeah, yeah, the situation is okay now. First of all, relate escalate immigration. See areas plus a set s years CR to s three maybe It's solid now. First of all, you have to balance the sulfur Adam. No cell phone at them. They can be balanced now. There are, you know, eight cell for cell there at alleges. And three cell phones are very delicious. So in threes are 24. So multiply it to see how terrestrial get 24 so far similarly multiplied by three to assent. 32 cent. So you gained 24 means all four items Surveillance now chromium 8 to 5, 16 directions, but only one chromium at LHs. So put here 16 food here. 16 So 16 Colombian on both sides than 24 self around both sides. So this is what a balanced chemical equation, Ben? Yeah, E immigration is NH three guys bless two guys give an H four f, I guess. Plus, I am a free gas. The balance situation is balance. Mhm. Immigration is so first of all races Skeleton equation That is N s. Three guys plus at two guys. Yes, you Yeah, yeah. Two guys gives and h four f guys plus three gas. So if you see properly in this equation night oceans are balanced and delicious and marriages but hydrogen. There are three at alleges and forehead marriages, then flowing to, uh, lectures. But I just There are four. There are four? No, uh, enough Florentine. So three plus four. And here, too. So to balance it so mhm if you multiply uh, this. See, there are three flooring over there. So obviously or to multiply these 32 NH four f. Okay, 32 and H four f. So what? Look, it is three and h four year reign. Now, once you're 83 NH four. If there are four night ocean and directors and only one night ocean, it alleges, so multiply for two NH three, then flooring three plus 36 directions and two floor inside alleges. So multiply this by three. Multiply this by three stuff. Okay, so this sort of balance situation, then f one f yeah. Yeah, the equation is is he too? As so I need less and still guys gives is he sounded plus H two s gas. The balance situation is violence. Okay, The situation is yeah. You know the skeleton equation. Your great finished a Z to s s. Plus it's two guys, I guess, is yes. Bless a stress gas, The sort of skeleton equation. Now, if you see properly, there are two silver at alleges. So directors only one silver. So multiply these 22 silver items now. Hydrogen surveillance self there is balance. Okay, so everything is balancing this issue. The next one is Yeah. Yeah. And see, nine days or two guys girls or three years? The balance situation is yeah, balance. Aggression. Okay, can the return as follows? So first right, the skeleton information before proceeding to balancing ossification. Right? The skeleton. Now at the latest, there are no action. But what direction? Their own reaction. So multiply at alleges by three will get six and multiply at directions by two. Again. We'll get six, then. Uh huh, Yeah. Next the equation. That is a NATO I saw 38 years plus a sect. Oh, solid. Yes. And I two s two or three and a two x two or three gas. Now you know the balance situation Balance equation. Can we re done mhm by writing skeleton equation? So frustrate the skeleton equation. That is my name too. So three acquiesce plus a set. Selene gives and I do H 203 Yes. Bam. Mhm. Yeah. So in this situation, you know, auction items are 33 celebrating one here to, uh, celebrate Times are here nine. But here three. So differences of you can say six. Sell for Adams. Okay. Yeah, yeah, yeah. So you know, in order to balance this this essay is there a set? So multiply this by eight they get 16 so young. So if you multiply this also by eight did you get 16 sodium itself for itself? For 16 Scalpers are the trees are 24 options and trees are 24 option items. So the equation is balanced then thanks a lot.
