I need help answering some questions:1Explain why the cryolite and aluminium oxide mixture must be kept molten for electrolysis(Is it something to do with the particles and that they can move around better than in a solid?)2Why is a mixture of aluminium oxide and cryolite used, rather than aluminium oxide alone?3Write half an equation to show the reaction at a positive and a negative electrode.4Explain why the extraction of aluminium in this way is reduction(oxygen is lost and electrons are gained?)5Explain why the carbon anodes need to be replaced at regular intervals.Please helpThanksXxxx
I don't think it's weird to wear pajamas when you're running down the block to the store, or downstairs to do laundryHowever, I've found it is humiliating to be seen by someone you know when dressed like that, caught in the midst of doing one of those thingsMy motto is, before you step out the door, make sure you're wearing something you'd be okay with anyone who lives in your neighborhood seeing, because you never know.
It was cute when you were a teenager, but now it's notI can understand if you have to rush to move your car, but put a robe over itDon't forget to wear slippersI wouldn't go shopping in pajamasHOWEVER, wearing pajamas to intentionally embarrass your kids at their school and forever send them to therapy is priceless, especially during Halloween and April Fool's Day;)
The lady next door used to water her plants in the morning wearing only her pantiesShe weighs 555 poundsI think if we have to look at that, you can wear your pajamas.
Sorry, but you're not a child.I understand you're only going to move your car or do something simple, but you're AN ADULT, not a child being dragged outsidePut on sweat pants and a t-shirt at leastConsider THIS: you wear pajamas to SLEEP in your BED.now you're wearing these clothes out in dirty streets regardless of how close it is to your homeTo do this on a regular basis is just not cool - and you're probably dragging dirt back to your bed if you put the same pajamas on laterAnother apology, but it also makes you look trashy to always come out in your pajamasYou should NOT be going to the market - even if it's a block away - in your pajamasYou're screaming I don't care about how I look in public and people don't look too fondly on those who can't even put a decent pair of pants on.
needs to be molten so the particles can move around as aluminium cannot dissolve into a liquid cryolite reduces the melting point of Al by half so from 2000 degrees C to 1000, cheaper for industries at anode (positive electrode) 2O 2- O2 + 4e- at cathode Al 3+ + 3e- Al reduction is the process of gaining electrons or loosing oxygen, in this case it lost oxygen (from Al2O3 to Al and O2) the carbon will react with the oxygen produced to form carbon dioxide, thus over time it will corrode and so will need to be replaced
