# When 0.100 mol of carbon is burned in a closed vessel with 8.00 $\mathrm{g}$ of oxygen, how many grams of carbon dioxide can form? Which reactant is in excess, and how many grams of it remainafter the reaction?

## $\mathrm{m}\left(\mathrm{CO}_{2}\right)=4,4 \mathrm{g}$$\mathrm{m}\left(\right.$ excess, $\left.\mathrm{O}_{2}\right)=4,8 \mathrm{g}$

for questions. 82 Ah, we have, Ah, cell phone. One more carbon being burned with Austin and then reforms. Theo too. So what would be the mass off our Theo, too? And then which we agent will be in excess. And also, what will be the remaining mass off the way agent? All right, so first of all, we have to bust Bannister chemical reaction. We make sure everything in balance. So we have carbons. Ah, reacting. Reverse it and we'll see what you actually, everything's upon. So we don't have to Ah, bon set. Okay, So the next step is we are come where? Everything to limbo Moe's Because we already have come in in number. Most wishes to convert that, um oxygen Thio limbo mo So we were eight. Divide by fortitude. Beware to oxygen. Zero points. You're five. Most off posture. Okay, so in order to fully we at with all the carbon Ah, you will need a seal form one more off oxygen. Ah, we got the reason is that this 1 to 1 ratio so safe from one carbon we need just soup on one more off oxygen and yet we can see that we have Maur much more oxygen there we need. So that's why all sexual well being accessed the carbon we've been emitting. So we already answers the Newman thing. We re their carbon. Ah, sorry. The limiting is carbon. The excess is also your name thing in common. The excesses would be awesome. All right, so we're going to take the number of more than anything creation. And then you start if I the maximum amount off. Um, but the part that Soviet going to just stay for one bowl and then we are looking the more the way show we have. Ah, common to see what you mean. The way show is 1 to 1, that's well, so at the same time, we have syrup on. One more come downside being produce. All right, so, uh, where we further convert that to master tomorrow by the more than mass off. So to Ah, So it's you. It will be Ah, uh, troll toe 44. So we have a 4.4 gram for Seo to being produce sword. If Adam s off our suits, you and then we find that all the excess will be oxygen. So what would be the remaining Ah, mass off the excess oxygen. So from here, we know that we have seo 0.25 frames and the oxygen being concentrated reaction. You see a 0.1. So the oxygen we may well be equals to 0.25 months upon once, or soup from 15 more and we try to convert that back to the mass. Ah, it will be 4.8 quid for excess oxygen being we mean in the reaction vessel after off the carbon being burnt.
