In a combustion reaction, 46.0 g of ethanol reacts with 96.0 g of oxygen to produce water and carbon dioxide. If 54.0 g of water is produced, what mass of carbon dioxide is produced?

All right. So we know 46 grams of the ethanol. We don't actually have to know the chemical form of this. So we have 46 grams of ethanol is gonna put e are actually out of. We don't even need symbol. We didn't know the mass. So I will put down here at the knowledge is so we know for six grams of what, pull us 96 grams of oxygen. I'll put that right here on 96.0 grams that I'll put oxygen. That was feel to You have to know this part. I'm just keeping track of it for you. And we know that it's going to make 54 grams of water. Put that down. 54.0 grams of H 20 plus some amount. What is that amount going to be? While this is actually really easy question, you have to know something called the Law of Conservation of Mass and how it applies to a chemical equation. Law of conservation on right that I got down again. Law of Conservation of mass. Well, this just tells us that matters not created nor destroyed. So in other words, for chemical equation that means is that the mass must be mass is the same. Write this down is the same in the reactant and product acting's and products. And when I say mass, I don't mean massive certain camp climbing the total mass. So let's put a little note here, too. We can put total massive feel like that's going to trip you up. Total mass is the same in the reactions and products. So let's take a look out what the masses in the reactive. So in the reactant, we have 96 plus 46. That's going to give us a nice number. 152. What's 142 142 point of Grant spoke, and that's gonna equal whatever is on the right side. So 54 plus some numbers and call X. We're gonna actually just solve this. Using some simple algebra put, the programs here is complete, So to get a calculator, if you need it will be 1 40 to minus 54. That's going to give us 88 grams of X equals 88 grams. So that's how many grams of CO two all right. That's all

But so for the mass of water and ethanol in this 10 grand mixture, let's let X speed the mass, uh, water. And will that Why be the mass? Uh, the ethanol. And we're told that X plus Y is equal to you 10 grounds. We also know that, uh, 46 grams of C two h 60 produces 54 g of h 20 from the story commentary of the reaction. So, um, X with an equation here, X plus 54/46. Why is equal to one to seven. This is beast on the mass of water. Uh, that is produced in the combustion. So substituting equation one and to so I can rearrange this, um, X is equal to 10 minus why I can take that and substitute that in here and sold for why and why will find his equal to 7.30 So the mass of the Fono works out to 7.30 g and the mass of the H 20 we defined as 10 minus X, which would be equal to 2.70 g. So the mass of the ethanol and the mass of the water in this 10 grand solution

Yeah. First of all, let's have a look what all is given in a problem. Given this mass of hydrocarbon, That is 40 g mass of oxygen. Yeah. 10 g mass of carbon dioxide produced Is 27.5 g. And what we're supposed to find out is we have to find the mass of water produced. Mm. My soft water. Mhm. Yeah. No. We know that Hi Drew cousin plus oxygen will form CO two plus H talk According to law of conservation of mass. According to law of conservation of mars. Yeah. Yeah. Mass can neither be created nor be destroyed. This we can say that massive reactant. Yeah. Is equal to mass of product. Hence we can say that for tape plus 10 is equals to 27.5 plus X. With p equals to 27.5 plus x. So x equals to 22.5 g.

Okay, Answer for part A right here. We have to write the complete balance occasion for the converse generation off the compound. Maternal. So your compassion of carbon containing compounds with or two makes you two in is to s product in for these energy. So the balance efficient for the given compound Trump is here to make an all plus or two is toe missed c 02 place energy. Yeah, So here we have to add because efficient three. And here we have toe add coefficient for interior also for So this is the violence situation for the combustion off meta north. And unself forgot me here we have toe right, the balance chemical equation for the compassion off for beautiful. So we have C four. It's night or it less or two. Uh huh. C 02 plus is toe or right here. We put six, you fool in 25 So the equation become balanced. Okay,
