Fe2O3 + 3CO ---- 2 Fe + 3CO2If you start with 0.2521 moles of Fe2O3 and 0.5543 moles of CO, determine the following:a). the maximum amount of Fe formed, in gramsb). the amount of excess reactant, in gramsPlease show work out for both so i can understand this better.
I have heard horror stories about flushing tranny, I wouldn't recommend it. However, it is a good idea to just have fluid and filter changed. Any shop can do that for you.
The fact is, if you service the transmission every 15,000 miles there is no need for a flush. don't do the flush. all these places muffler/brake/oil shops offer this stuff don't do it. just keep tranmisson fluid filled and don't let it run low for a long period of time. you will be okay.trust me
There's a shortage of CO since you need 3 moles of CO for every mole of Fe2O3. You need 0.756 moles of CO. Since you have only 0.554 moles of CO, Let's do it this way: 1 mole of Fe2CO3 with 3 moles CO yields 2 moles of Fe. 0,252 moles Fe2CO3 with 0.756 moles C0 would yield 0.504 moles Fe. Because of the shortage of CO, you will get only 0.554 / 0.756 x 0.504 moles Fe
because of the ratio: Fe2O3 + 3CO ---- we needed 3 timeas as many moles of CO , as we had moles of Fe2O3, but they didn't add enough CO to have 3 times as many moles,. CO is the limiting reagent using the ratio 3CO ---- 2 Fe , and the molar mass of Fe, find the maximum amount of Fe formed, in grams: 0.5543 moles CO [(2mol Fe)(55.845 g/mol)] / 3 mol CO your answer(4sigfigs): 20.64 g Fe using the ratio Fe2O3 + 3CO ---- , find the moles of Fe2O3 used in the reaction: 0.5543 moles of CO 1 mole Fe2O3 / 3 mol CO 0.1848 moles of Fe2O3 were used find the moles of Fe2O3, left over: 0.2521 mol Fe2O3 - 0.1848 mol Fe2O3 used 0.0673 moles remain find b). the amount of excess reactant, in grams , using the molar mass of Fe2O3: 0.0673 moles Fe2O3 159.69 g/mol 10.75 grams Fe2O3 your answer (3sigfigs in 0.0673 moles): 10.8 g Fe2O3 remain unreacted
read your manual if you have one.i had an 1989 with 289000 yes almost three hundred th miles on it and only had the flued changed three times. the car rusted away but the v6 and drive trane were still going strong. change the oil every 3000 miles
