Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, it is used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic processing|aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.

Aluminium foil is widely sold into the consumer market, often in rolls of 500 mm (20 in) width and several metres in length.It is used for wrapping food in order to preserve it, for example, when storing leftover food in a refrigerator (where it serves the additional purpose of preventing odour exchange), when taking sandwiches on a journey, or when selling some kinds of take-away or fast food. Tex-Mex restaurants in the United States, for example, typically provide take-away burritos wrapped in aluminium foil.

Aluminium foils thicker than 25 μm (1 mil) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.

Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is difficult to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers. When the sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the perception that favouring a side has an effect when cooking. While many believe that the different properties keep heat out when wrapped with the shiny finish facing out, and keep heat in with the shiny finish facing inwards, the actual difference is imperceptible without instrumentation.The reflectivity of bright aluminium foil is 88% while dull embossed foil is about 80%.

Aluminium (or aluminum; see spelling differences) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery white, soft, ductile metal. Aluminium is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth's crust. It makes up about 8% by weight of the Earth's solid surface. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals.The chief ore of aluminium is bauxite.

Aluminium is remarkable for the metal's low density and for its ability to resist corrosion due to the phenomenon of passivation. Structural components made from aluminium and its alloys are vital to the aerospace industry and are important in other areas of transportation and structural materials. The most useful compounds of aluminium, at least on a weight basis, are the oxides and sulfates.

Despite its prevalence in the environment, no known form of life uses aluminium salts metabolically. In keeping with its pervasiveness, aluminium is well tolerated by plants and animals. Owing to their prevalence, potential beneficial (or otherwise) biological roles of aluminium compounds are of continuing interest.

The earliest citation given in the Oxford English Dictionary for any word used as a name for this element is alumium, which British chemist and inventor Humphry Davy employed in 1808 for the metal he was trying to isolate electrolytically from the mineral alumina. The citation is from the journal Philosophical Transactions of the Royal Society of London: "Had I been so fortunate as to have obtained more certain evidences on this subject, and to have procured the metallic substances I was in search of, I should have proposed for them the names of silicium, alumium, zirconium, and glucium."

Davy settled on aluminum by the time he published his 1812 book Chemical Philosophy: "This substance appears to contain a peculiar metal, but as yet Aluminum has not been obtained in a perfectly free state, though alloys of it with other metalline substances have been procured sufficiently distinct to indicate the probable nature of alumina."[69] But the same year, an anonymous contributor to the Quarterly Review, a British political-literary journal, in a review of Davy's book, objected to aluminum and proposed the name aluminium, "for so we shall take the liberty of writing the word, in preference to aluminum, which has a less classical sound."

The -ium suffix conformed to the precedent set in other newly discovered elements of the time: potassium, sodium, magnesium, calcium, and strontium (all of which Davy isolated himself). Nevertheless, -um spellings for elements were not unknown at the time, as for example platinum, known to Europeans since the 16th century, molybdenum, discovered in 1778, and tantalum, discovered in 1802. The -um suffix is consistent with the universal spelling alumina for the oxide (as opposed to aluminia), as lanthana is the oxide of lanthanum, and magnesia, ceria, and thoria are the oxides of magnesium, cerium, and thorium respectively.

The aluminum spelling is used in the Webster's Dictionary of 1828. In his advertising handbill for his new electrolytic method of producing the metal in 1892, Charles Martin Hall used the -um spelling, despite his constant use of the -ium spelling in all the patents[58] he filed between 1886 and 1903. It has consequently been suggested[by whom?] that the spelling reflects an easier-to-pronounce word with one fewer syllable, or that the spelling on the flyer was a mistake.[citation needed] Hall's domination of production of the metal ensured that aluminum became the standard English spelling in North America.

Q:for each of the following ions indicate the total number of protons and electrons in the ion for the positive ions in the list, predict the formula of the simplest compound formed between each positive ion and the oxide ionfor the negative ions in the list, predict the formula of the simplest compound formed between each negative ion and the aluminum ion.AFe2+B.Fe3+C.Ba 2+D.Cs+E.S2-F.P3-gBr-hN3
For all atoms the number of protons atomic number, so just look it up.ALso for atoms, no of protons no of electons, so you know that, tooFor positive ions, you must have LOST electons, so to determine how many electron each positive ion has, it's (atomic number - charge on the ion)For negative ions, you must have GAINED electrons, so no of electrons (atomic number + charge) egO has 8 protons, so also has 8 electrons O^2- has (8 +2) 10 electrons Work the rest out yourself! The oxide ion (O^2-, above) has charge 2-, so you must cancel that out with your cations aFeO bFe2O3 cBaO dCs2O The aluminium ion is 3+, so e.Al2S3 fAlP gAlBr3 hAlN
Q:i stole about 1000 dollars worth of aluminum tubing and got charged with 2 feloniesTheft 1 for stealing the and criminal mischief for cutting the tubes into peicesIm only 18 and i have a clean recordi go to court in a few weeks and was wondering if it is possible to plead down the felonies to misdemeners? and also do you think i will have to go to jail? for how long? what will the punishments be? thankyou
It is possible to have them reduced, but that has to be approved by both the prosecutor and the judge.
Q:what happens when 1)paper 2)aluminium sheet is wound round a wooden cylinder and heated over bunsen burner?
1) The paper will catch fire and burnDepending on how much paper there is and how long the whole apparatus is held over the flame the wooden cylinder might catch fire too2) In the short run, nothing will happen except the aluminum gets hotAfter some time passes the wooden cylinder on the inside will start to scorch from touching the hot aluminumAfter even more time passes the wooden cylinder might catch fire, if some part of it is exposed to the air.
Q:best describes the highest energy valence electron in a ground state aluminum atom?a) 2, 0, 0, 1/2b) 2, 1, 0, 1/2c) 3, 0, 0, 1/2d) 3, 0, 1, 1/2e) 3, 1, 1, 1/2
since we have for the valence electrons in Al: 3s2 3p1 n3 l1 I think the answer is (e) but am not sure
Q:I saw dissect natural leafs for greetings cards and in some occasion for jewelry, I want to know the technique(s) to do dipping in gold and/or silver; I know that electrolysis works only on metal, It does works in organic compounds?
at your age, you've vigor, and you want pleasure and peers.you're mature for sixteen.and might be your peers aren't developing at the equal stage as you're.check out having a couple of peers no less than a yr older thaan you.might be two years older.however dont hand around in golf equipment,it's not authorized for you butit slow will come so quick
Q:What I want to do is make all of my computers wifi functions more powerfullPreferably for freeAny way you know of doing that?
The above answer is commonly precisebesides the shown fact that with extra moderen instantaneous routers particular desktops could be different as authorized via the mac handle(something, not merely desktops,with the skill to connect with the internet has a mac handle.) in the adventure that your mac handle isn't different as between the addresses which would be recognised by potential of the instantaneous router, you're locked out of connectingSo if the church around the line has executed so, you will not be waiting to connect with their instantaneous communityby potential of ways, the mac handle i'm speaking is a uniquely difficult coded identifier for kit.
Q:I am going to make some brownies for Xmas and I don't know where I can find some paper baking cupsI have been looking party supply stores websites and also at the grocery store but i can't find anythingDo you think you can help me out?
Looks like everyone is on the same path for youThe grocery store is your best betEach store may stock it in a different place, so look in the aisle for baking goods firstEspecially at this time of year, they'll have holiday patterns so they may be in an end cap (the shelves that are at the end of each aisle as you turn from one aisle to the next), or in the small cardboard displays that stand next to the shelves (the ones you have to maneuver your cart around because the display is in your way)Also check in the aisle where they stock aluminum foil, wax paper, etcand finally, in the section where they have kitchen gadgets, etcOther stores that will carry them include wal-mart, k-mart, target, dollar stores and even Michael's or Hobby Lobby (look in the section where they keep baking geegaws like cookie cutters, Wilton pans, etc)Happy bakingand Happy Christmas!
Q:I just made some baklava to take to class tomorrow for my project, but on the instructions I followed, it said not to cover it as it will get soggyIt's cooled down by now, but I don't really know what to do with itIt's in a 9x13 aluminum pan that came with a clear plastic lidDo I just put the lid on it and leave it out or should I put it in the fridge uncovered?
it doesn't it creates electrical arcs, due to the microwave radiation eventually, this generates enough heat to start it on fire.
Q:I'm not so sure exactly what happened to them - I was doing a project on electrolytes, and I was using a multimeter for measurements of current and resistanceI put the probes in a solution of table salt and water, and I had two pieces of aluminum foil on either side of the plastic container the solution was in (these sheets of foil were serving as conductors, so I could figure out the resistivity of the solution)I had two copper wires connected to either terminal on a 6V batteryWhen I connected the copper wires to the aluminum foil, the solution started fizzing at the edgesI put the probes in and took some readingsWhen I pulled them out, the probe nearest to the conductor connected to the negative terminal had a copperish looking coating on it, along with some black coatingAlso, the foil connected to the positive terminal had disappeared, like something ate at it (it had holes in it)I'm pretty sure this was a type of chemical reaction; any ideas on how to reverse/fix it?
