That's so we're doing question numbers in the aid of Chapter five in chemistry Central Science to Die Antal either See, for ages ten and oh, well, a flammable cos once you surgical anesthetic has it as as as is shown right here, The complete combustion of one mole of see for is ten o to co two and issue A ll yield Delta H minus two seven twenty seven, twenty eight, twenty, seven hundred twenty three point seven. Killer Jules, right, Abounds equation for the combustion of one mole of O of ah diable Either there. And then we're going to use the information problem to catch the Delta H f for diable either. So if we're dealing with one mall of our settle of our die, it'LL either there's going to have a one in front of it comes in and sees a different color. Killer just emphasized the answer So us. So we have we have forces over here. We have one over here. So we have two out of four over here. No, we have five Hydra. We have ten agents here to overhears You have about five, because five times, Suze, equal to ten. Now we have. Oxygen's on the right. We have eight and we have five over here. So we have thirteen on the right. We have three and we have one of we have to. Here we have one. Here's that story on the left. So we're going to put this one aside, so we need twelve more oxygen's. So we're going to go to six in front of here here, and that's going to be our balance question for one bowl of Di Ato either. Next we're gonna find the Delta H Value. So remember the music has little dealt h reaction is you could tell teacher products might still teach. React things so modest, too. Seven, two three. In fact, let's just send it up like this. It'LL make it less confusing. Remember, this is Hess's law. So now we're going to switch things around. So Delta H R. Is equal to Delta H P minus delta H reaction. So the member since auctions and elements standard states that's going Teo, give us eight at age. Those ages equal zero killer Just Ramon. So our only reacting is going to be our diet a liter, so don't so the age of of iron diet either is going to equal to some of the products. Manistee minus the reaction. So we got five times negative to eighty five point eight plus four times three nine minus three. Ninety three point five five minus negative to seven. Three. Yeah, minus two seven two, three point seven. So we're going to put everything into a calculator. Tell that to H F. For this reaction is going to be minus two seventy nine point point three. Kill a Jules Promote knows that's going to be deducted. Age of information for our diet a liter.
