number of moles of electrons needed to liberate 54g of aluminium using electrolysis of molten aluminium chloride
So Al ions have a charge of 3+Look at the following equation: Al^3+ + 3e^ - gives Al (the three electrons (negative) cancel the positive charge on the Al ion so to produce one mol of Al u need 3 moles of electrons molar mass of Al 27 g Therefore the number of moles of aluminium in 54g 54/27 2mols if u need 3 moles of electrons to produce 1 mol of Al, then u need 32 6 moles of aluminium to produce 2 mol (54g) of aluminium hope that makes sense to you:D
get like 1000 ballons put them in the room put water ballons in his drawers and closets replace his lamps wiht patatoes but keep the celing light their replace his pillows with pillowcases fulll of paper put fake spiders and snakes in his bed and find another thing to do with those water balloons
This would be hard to do but get a trashcan and fill it up with water (or something else) and lean it against his doorWhen he opens gallons of water will come flooding out onto him(will depend on which way the door will open) funny as hell
Fill the whole room up with fish innards and animal waste until the point the whole thing is nearly bursting, then close itThe fact that you have a whole week makes it even better so the stuff can start to rot until he returns.
Wow, an open budget? There's so much stuff you could do! One thing you could try (not really a prank, but fun) is buying a whole lot of multi-colored Post-Its and covering his entire room in themEven the carpet and wallsSo the carpet would be one color, the walls another, and the dresser another, and the bedWell, you get itAnother thing you could do is make a Rube Goldberg machine that activates when he opens the door and ends up doing something coolYou could cover his room in underwear or shaving creamOr bothMaybe even take a bunch of thumbtacks in buckets and spill them all over his roomIf you want to go low scale, take everything out of his room, put it in your room, and if you have numbers on your doors, switch the numbers of something so if his room was 215, have it go from 214 to 216Once he finally figures out which room is his, he'll enter and find it emptyP Or just re-arrange everything in the roomAnd please tell me what you end up doing!
