Hello friends in this video with alone hard to do so starts geometric calculations. So as you can see, you have been given a chemical equation in front off you, in which iron three oxide is reacting with carbon monoxide to give Ireland on carbon dioxide. Okay, so in this, that's what we have to start to questions. And this or the first question is we have to find out the maximum mass off Ireland. Maximum mass off irony produced using four for before Graham's Off Island three oxide. Okay. And the next question Benito answer, is the mass off carbon monoxide produced mass off carbon monoxide produced, not produce, required. So massive carbon monoxide required massive carbon monoxide required to react with 4 54 grams off iron. Three oxide, right? So it's simple. So there are two questions We have been given an equation. We need to find out what is the maximum mass off island, which is produced when we used 4 54 grams off island three oxide. And also we have to find out what is the mass of carbon monoxide required to react with fourth of before Graham's off every wall tree. Okay, so before we go ahead, we can just stick with. There are equation is balanced or not, So we can see here There are two atoms off Iran on the reaction site on two atoms off. I don't on the correct size as well. Then there are six atoms of oxygen on the react inside and six atoms off oxygen on leopard upside. Then three atoms of carbon under react inside and three atoms of carbon on the correct side. So this equation is perfectly balanced. Now, the next step producers, we have to find the molar masses off all the compounds here. Right? So how do we find the molar masses? So we can refer to the periodic table cedar, the mass off each of the we can check them ourselves, one of them off each element. And then we put added up. So, for example, so I don't oxide is to indo the atomic mass off ironist 56 a little bit too in 2 56 plus three into 16 because the atomic mass of oxygen ist 16. Rachel, this will give us toe molar mass off island three oxide. So if we do this, it comes out to 1 60 grams per moon so similarly began out of four carbon monoxide as well. So carbon monoxide comes to 28 grams for more and ironist 56 grams on government oxide. Carbon dioxide is four p four grams. Okay, so you can see the coefficients here. So it means Didn't the reaction three multiplied or three moles of carbon monoxide is used up. So basically three into 28 grams off carbon monoxide, less used up similarly to multiple 56 grams off ironist produced also three multiply by 44 grams off carbon dioxide is produced, right? So let's get the final calculation here. So 1 60 gram off every two or three is reacting with three in 28. So that's calculate what is three into 28. So three multiplied by 28 which is 84. So it reacts with 84 grams off carbon Morneau oxide. Okay. And then it reacts with 50. It produces 56 grams off it produces 56 into 2 56 into two s. 112 Right. So it produces 112 grams off iron. 112 grams off item. Okay. And then And then we have to. We get three multiplied by four before Graham's off. Carbon dioxide is a three. Multiply before before Gramps off topping dioxide. So 13 to graham off carbon. Right? So the simple So what? What has happened here? 1 60 gram off island three oxide reacts with 84 gram off carbon monoxide and gives 112 gram off Iran. And with her, Liza 1 32 grams off carbon dioxide. Okay, so but this basis, basically, we can try to solve our two questions. Okay, So our first question is, we have to do it. Remind the mass off island off pain from 4 54 gram off Ireland. Three oxide. So from the abo calculation, we come to know that 1 60 gram off island three oxide gives 112 gram off I'll right? So now we have been given 4 54 grams off island three oxide. So let's assume it produces a gram off iron. So how do we care? FedEx We don't cross multiplication, so X becomes 112 multiplied by 4 54 divided by 1 60 So let's do the calculation using a calculator. So it's 112 multiplied by 454 divided by 1 60 Right. So it comes out to be 317 grams off. I'd run. Okay, so this will be down. So for the first question, so the question waas massive are not central 4 54 grams off a feat war tree. So dance arrest 317 grams off. I'll Okay, so let's go towards the be part of the question in the be part of the question we need to do to mine. What is the Mars off? Carbon monoxide required to react with 4 54 rounds off island three oxide. Right. So as we did the calculation before become to know that 1 60 gram off iron, three oxide, 1 60 gram off iron, three oxide. React with it before Brahmos carbon monoxide. Okay, so we can take this of the reference fall RB. But so 1 60 gram off 1 60 gram off island. Three oxide reacts with it before graham's off. Carbon monoxide. Now we have 4 54 grams sauce. I didn't three oxide. All right, so let's as you the amount off carbon dioxide, carbon monoxide, which is which is reacting with the 40 people gram of every toward race. Why, Gramps? So why will be it before my reply by 4 54 divided by 1 60 So 84 multiplied by 4 54 Divided by 1 60 So let's do the calculation now using a calculator. So 84 multiplied by 4 54 divided by 1 60 So it gives to 38.35 grams off garden with bauxite. I hope you understand. Thank you so much.
