ok so my mother in law likes to buy us stuff and not tell us until after she buys it (sometimes we get random packages in the mailthe last one was a meat slicer, yeah i dont know either) but she had a pampered chef party, and apparently as part of her hostess rewards she could get a 13 peice nonstick cookware set for half priceso naturally she buys it for meShe just called to tell me, but I won't get it for a while because she lives 4 hours awayI love pampered chef gadgets, I have a ton of themHowever, I have never used their cookwareSoi was just wondering if anyone out there has the non stick setdo you like them or not? and any helpfull tips on caring for/cooking with them?Thank you!
The mass (or moles) of iron on the left side of you equation must be the same as on the rightYou have 16g of iron on the right side of the equation, therefore the mass of the iron fraction of the Fe2O3 that you started with is also 16gThe fraction of Fe in Fe2O3 is (MW of Fe x 2) / (MW of Fe2O3) or (55.8 x 2) / (159.6) 0.699 so the mass of Fe2O3 that you need is 16g / 0.699 22.9g of Fe2O3 The left side of your equation says that for every mole of Fe2O3 that you start with, you use 2 moles of Al The moles of Fe2O3 that you have is (mass of Fe2O3) / (MW of Fe2O3) or 22.9g / 159.6 0.143 moles of Fe2O3 The mass of Al to be used then is 0.143 moles x 2 x MW of Al or 0.143 x 2 x 26.98 7.72g of Al Similarly as we did at the start, the mass (or moles) of aluminum on the left side of you equation must be the same as on the rightYou have 7.72g of aluminum on the left side of the equation, therefore the mass of the aluminum fraction of the Al2O3 that you end up with should also be 7.72gThe fraction of Al in Al2O3 is (MW of Al x 2) / (MW of Al2O3) or (26.98 x 2) / (102.0) 0.529 so the mass of Al2O3 that you end up with is 7.72g / 0.529 14.6g of Al2O3 You can check your work by adding up the masses on each side of the equation to make sure that they are equalIn other words, the mass of Fe2O3 plus Al should equal the mass of Fe plus Al2O3For this question then you have 22.9g + 7.7 g on the left side of the equation and 16g + 14.6g on the rightBoth sides equal 30.6g, the conservation of mass holds, and the world is saved.
This Site Might Help YouRE: Fe2O3(s) + 2 Al(s)→ 2 Fe(l) + Al2O3(s)? What masses of iron(III) oxide and aluminum must be used to produce 16.0 g iron? What is the maximum mass of aluminum oxide that could be produced?

First of all, LOL on the not touching the stoneware! I know what you mean, but if you can find a friend to season it for you to get it past the new stage, you will love using itUsing it: The cookware is wonderful, and your MIL is amazing for giving it to youYou won't want to use any metal utensils in it because they'll scratchUse the silicone scrapers or the nylon tools that you probably already have from PCI use mine every day and sometimes I have to wipe it out to use a piece a second timeI make everything from dinner to scrambled eggs to rice krispy treats in it and it will wipe clean with a paper towel for the most part - that's how good the non-stick isThe coating is baked on (not sprayed), so even if you scratch it, the coating won't flake and peelYou can put it in the oven for oven omelets or skillet cakes, tooThe pans have a heavy-gauge aluminum core so they distribute the temperature of the food really wellAnd a lot of people don't realize that you can use them for DEFROSTING your food too! I will put a package of frozen meat in a pan on the counter (or turned-off stove top) and flip it any time I walk byThe pan sucks the cold out of the food and it defrosts! Caring for it: Hand-wash the pans, lids can go in the dishwasherThe dishwashing detergent can damage the non-stick coatingThey are so easy to clean (except for around the rivets, but you'll be able to live with that because the pans are so nice to use) that you won't have any trouble with hand-washingNormally, there's no need to soak them firstYou can e-mail me through my profileHoller if you need any recipes for itMy favorite is the Turtle Fudge Skillet Cake!
