Problem 95

The standard enthalpies of formation of gaseous propyne $\left(\mathrm{C}_{3} \mathrm{H}_{4}\right),$ propylene $\left(\mathrm{C}_{3} \mathrm{H}_{6}\right),$ and propane $\left(\mathrm{C}_{3} \mathrm{H}_{8}\right)$ are $+185.4,+20.4,$ and $-103.8 \mathrm{kJ} / \mathrm{mol}$ , respectively.(a) Calculate the heat evolved per mole on combustion of each substance to yield $\mathrm{CO}_{2}(g)$ and $\mathrm{H}_{2} \mathrm{O}(g) .$ (b) Calculate the heat evolved on combustion of 1 $\mathrm{kg}$ of each substance. (c) Which is the most efficient fuel in terms of heat evolved per unit mass?

Answer

(a) Please see the explanation.
(B)Please see the work for solutions.

So we have these three passes say three age. Yeah. ControI for you, guy. Want to eat us upstairs alone? People want. So there's one absent id ready? 1/2 2nd Probably same three aces. It does. Whoa! Double back. Oh, I'm drinking. Yeah. And you know what? I could get here on guitar? Gonna say three and it's you have acid and see created as it's saturated Ondas flair It will be better off. It will be the best for you. You see, I'm off our gas like proper profane Catania The anger for no, that is not. But this question wantto produce off population before we arrive at our answer. So the first thing we have to ride the conversion reaction 40 each desk. So the product off comm Varsha off Andrea Koppel me, That is the compound ofthe carbon and hydrogen. Four out of the eyes covered outside. On what? So it's a once the you know the orders. The only thing to do is to live with Obama's it. Compassion is a reaction with obstacle and react compound with our city. That is what we call Khun question. So I can do it the second you see three aces. I have no concerns anyone of them. So I'm just writing them now. And it's hard to say three. Got it, right? Yeah. Okay. This fossil. I know I have three cover men on the right and on the left outside. So if our three year I have three cover after bananas, I'm ready on our city. Now this Give me to the last race. Six. I'm drinking if I had to. Here because I have for a limited way are five a year. Let me add two year So many have tto gusto for drugging for, I think. Now the Toyota actually, you know this I would be to a battery that is is close. Want us to close too? Don't like it at this, sis. Plus to it so I mean it. I also hear I mean, Doctor, get here. So all right for that one is Dallas. If we look at it, trickle down on the right, outside on the left, inside 31 on the left, outside for a regular Andi outside for either you're on the right outside for us to that It it oxygen on the downside. Thanks. I was told that 36 hours. So that's what that is. Six plus two. It actually on the right side. Its problems. So this one, Cora. Okay, now living biomass hydrogen straightaway. Here I count on. Okay. If I belong this druggie, If I am Valenti's this I tell you now, our sixth year. All right. Three year my hydrogen, maybe six african will be, What, three? Only three days ago How was one? My actually get to be alone. Local m e a r 16 year. See if maybe you have ideology and it. So if I bring so have toe to here. There, there carbon is bala and discover. So, sis, cover on the left hand side and there are six here. So, Governor, I'm gonna remain city. I absolutely be two times six. Pakistan love six that is entering. You think? I mean so that is a balance. So for the time. Okay, then after recover, recover if I'm drinking, so get it out for you. So now African will be safe for I'll be taking So our fight. So is pilots. That is the force contacted. Question now pieced Ocampa. Lady it off. Reaction for each for the conversion ofthe carcass reaction. So and eat of a reaction, it's going to be so mission. The eight of information. I'm the product. My enough summation of eight of fromage off. Artie, don't. So in the from the top table I have for the force The first question the 1st 1 that is for the girl okay, is goingto be in front of these three. Cover in there was right. We have three. Bye bye. Final 3 93 0.5 plus two. We have to water toe into enter pure rice Manners 2 85 Find it. You have only for good. They're my reactant. My panties. Kral Klein is said Andi, eh? Oh, and that information is 1 85 points. Well, we'll see. Siggy is this standard issue from a zero. So having these miners want sound 52 grand slam. Wow. I fine on doubt his mean mallows 1 93 when I was 37.5. I care for the 2nd 1 that is from peeling them for probably is going to be product as a way we have six oh, governed outside house minus three and 23 point Fine. We have six Warner. What Eyes Manners to 85. Why, it's artists are guarding from the table there. My nose, my reactant. I have to not forgetting the same until point for on up city we have now. Lady Oxygen is in strand us. They're going to zero. So the kind of man I take my calculator to get my house Everything. Give them Venice for found 16 I'm safe. Go got Remember, we have to pull off product back to Mullah Broccoli. So if I divide it, it's going to be mine off my family. By two, I would get two. 5 to 58.3 like my mom. So it's a hard one. He's probie. Eat off reaction. It's going to be just like in our three. Come on outside, Not three. We're looking at the reaction 93 0.5. But as far for what? And then our products I mean, the reactor, my nose. Wow, Propane. While Cyril three point next artist is the formation ofthe protein. Yeah, I see. It's a formation of actually Penis off oxygen seal with using standard state. So everything Yeah, is me and us to to Well, no, thank you family. So looking at these three death, say three, 84 say three aces a sentry it it so for a long gods. Hey, you can say we find out like that. He's long. Give us my nose, Teo 219.9. Thank you. With you. The highest. So they went out for Is it okay if we have to come back to one thousand one program off each? So want to know? Was this the amount off in that they would produce Bobby? So for the 1st 1,000 now we come after camp. Lydia Molecular Mass 11 of these. Give me three. Fast Dave. Well, it's one fastball, that is for Look, if I did the same thing Three Fast six, that'll be 42 found found. Except for this one. It's faster. Eight. 44 About that. So far, the 1st 1 that I want them a 1,000 gram off. If it's this one you want some? I was by by I know that I got my nose one. My three. Cell five. You know, more off safely. A four 11 ofthe city Create for one more. Save me for yes, if it's 40 grams. So the tyre night time for this one thousand five by my house. 1937.555 40. And give me my phone. It's for to be cell five. Yeah. And who's we do similar waiting for? Throw me 1,000. Well, then give me. I'm not one. Not 205 three. Oh, it's It's one more pieces. No, I wanted to at me. Oh, nine, you know? Yeah, nothing. Yeah, My nose, too. I'm maybe so. I want more. Is it? Yeah. 5 15 Defined by before I have my most five. Yeah. Why? Right through. You know them. We're getting negative before they listen. Now, it's also idea offline, So this one could be identified in the Now you're thinking on this one? I'm not saying life. Well, it's simple. Everything. It is the same. What
