Al + H2SO4 gt; Al2(SO4)3 + H2b) 6,71 g Aluminum requires how many grams of sulfuric acid to react completely?c) 6.21g of aluminum reacts with 12.95 g of sulfuric acidwhich comound is in excess? how much will be left over? How many grams of hydrogen gas will be produced?d) 62.5 g of aluminum reacts with 126.2 g of sulfuric acidhow many grams of aluminum sulphate wil be produced ?
i put a little water on the pan, cover with tin foil, (one sheet over pan) and bake at 350 for about an hour or sosometimes i rub butter on the chicken before bakingbest of luck to you.
Anna, before you can do any math (stoichiometry) you must balance the equation to obtain the molar ratios of reactants and products2 Al + 3 H?SO? → Al?(SO?)? + 3 H? : ratio of Al:H?SO? is 2:3, i.e we'll need 1.5 times more H?SO? than Al b.) 6.71-g Al x ( 1 mol Al / 27.0-g Al) x (3 mol H?SO? / 2 mol Al) x ( 98.1-g H?SO? / 1 mol H?SO?) 36.6-g H?SO? c.) We have: 6.21-g Al x (1 mol Al / 27.0-g Al 0.23 moles Al and 12.95-g H?SO? x (1 mol H?SO?/98.1-g H?SO?) 0.132 mol H?SO? c1.) 2 moles of aluminum needs 3 moles of H?SO? for complete reaction0.23 mol Al x ( 3 mol H?SO? / 2 mol Al) 0.345 moles H?SO? is neededWe don't have anywhere near that quantity of H?SO?, so it is the limiting reagentAL is in Excess! c2.) 0.132 mol H?SO? x ( 2 mol Al / 3 mol H?SO?) 0.088 mol Al will be usedThis leaves 0.23 mol - 0.088 mol 0.142 mol Al un-reacted c3.) 0.132 mol H?SO? x ( 3 mol H? / 3 mol H?SO?) x (2.02-g H? / 1mole H?) 0.267-g H? is produced d.) 62.5-g Al x (1 mol Al / 27.0-g Al) 2.31 mol Al - need 1.5 times MORE H?SO? 126.2-gH?SO? x (1 mol H?SO?/98.2-g H?SO?) 1.285 mol H?SO? - limiting reagent 1.285 mol H?SO? x (1 mol Al?(SO?)? / 3 mol H?SO?) x ( 342.3-g Al?(SO?)?/ 1mol Al?(SO?)?) 147-g Al?(SO?)? will be produced
Bake chicken at 375 to 400 degrees for about an hour.uncovered if you like crispy skin, covered if you like soft skinIf covered, just put a big piece of foil over entire panIf uncovered, baste every 15 minutes with pan juices to help keep skin Crispy-Moist If you want to lay them on a rack, make sure to have a drip pan underneathGrilling is usually done on an outdoor pit or an indoor grill on stovetop burners.
I usually make a Rice recipe with the chickenI make the Rice ahead of timeThen separately I soak the chicken in Sweet and Sour Sauce all dayAn hour or 2 before dinner, I make the chicken on a griddle inside the houseOnce cooked, I prepare a rectangle 2 to 3 inch high container, fill with foil, put in cooked rice, grilled sweet and sour chicken, peaches and pineappleLet cook for 45 minutes to 1 hourServe hot.
Yes , You can bake chicken instead of grillingGrilling is a form of cooking on an open grate or grill such as a BBQWhen you BBQ you usually baste the food with a sauce that flavors the food and also helps keep the juices inside the meatThe idea of laying the chicken on the rack of your oven does not equal a BBQWhat a mess in your oven, not to speak of the hardship of watching the chicken from outside the oven door or getting burnedWhen you bake the chicken, I would suggest an appropriate recipe for oven bakingYou can start by using a large foil pan sprayed or coated with oilIf you have a grilling pan for the oven, you can use that, lining the bottom with foil for a quicker clean-upPlace the chicken pieces on the panBake it at 350 degrees for about one hourWatch it and remove it a little early if you are reheating it at a later date and timeSeason with salt, pepper, and granulated garlic powderVery simple ingredientsWhen the chicken is almost baked, you can brush it with a BBQ sauce of your choice or a basting sauce recipe that you may look up on the internet or you can place the chicken parts in an oil sprayed roaster season it and roast them with a cover on it, and then remove the cover for the last 1/2 hour and baste the chicken as well to give it the flavor.
