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.



Coal (from the Old English term col, which has meant "mineral of fossilized carbon" since the 13th century)is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams. The harder forms, such as anthracite coal, can be regarded as metamorphic rock because of later exposure to elevated temperature and pressure. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen.

Throughout history, coal has been used as an energy resource, primarily burned for the production of electricity and/or heat, and is also used for industrial purposes, such as refining metals. A fossil fuel, coal forms when dead plant matter is converted into peat, which in turn is converted into lignite, then sub-bituminous coal, after that bituminous coal, and lastly anthracite. This involves biological and geological processes that take place over a long period. The Energy Information Administration estimates coal reserves at 948×109 short tons (860 Gt).One estimate for resources is 18 000 Gt.

Coal is the largest source of energy for the generation of electricity worldwide, as well as one of the largest worldwide anthropogenic sources of carbon dioxide releases. In 1999, world gross carbon dioxide emissions from coal usage were 8,666 million tonnes of carbon dioxide.In 2011, world gross emissions from coal usage were 14,416 million tonnes.Coal-fired electric power generation emits around 2,000 pounds of carbon dioxide for every megawatt-hour generated, which is almost double the approximately 1100 pounds of carbon dioxide released by a natural gas-fired electric plant per megawatt-hour generated. Because of this higher carbon efficiency of natural gas generation, as the market in the United States has changed to reduce coal and increase natural gas generation, carbon dioxide emissions have fallen. Those measured in the first quarter of 2012 were the lowest of any recorded for the first quarter of any year since 1992.In 2013, the head of the UN climate agency advised that most of the world's coal reserves should be left in the ground to avoid catastrophic global warming.

Coal is extracted from the ground by coal mining, either underground by shaft mining, or at ground level by open pit mining extraction. Since 1983 the world top coal producer has been China.In 2011 China produced 3,520 million tonnes of coal – 49.5% of 7,695 million tonnes world coal production. In 2011 other large producers were United States (993 million tonnes), India (589), European Union (576) and Australia (416).[9] In 2010 the largest exporters were Australia with 328 million tonnes (27.1% of world coal export) and Indonesia with 316 million tonnes (26.1%),while the largest importers were Japan with 207 million tonnes (17.5% of world coal import), China with 195 million tonnes (16.6%) and South Korea with 126 million tonnes (10.7%).

Q: For each of the following ions, indicate the total number of protons and electrons in the ionFor 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 ionP3- Cs+ Br -Fe3+
chemical change because it changed to a new substance
Q: I forget how to determine the charge of an element based on its electron configurationI know it has to do with how electrons fill outer orbitals, but I have seen too many conflicting 'methods' and now i am confusedFor example, what is the predicted charge on a molecule that has the electron configuration of (1s2)(2s2)(2p6)(3s2) The answer key say +2, but I don't see itHow would you figure it out if you were given the electron configuration for aluminum or fluoride?Thanks
The highest energy sub-level is the 3s where there are two electronsWhen a metal ionizes then the electrons are lost from the highest sub-level(s), hence the +2 chargeAluminum has three electrons in the highest energy level (n3) - [Ne] 3s2 3p1 - so it will have a charge of +3Fluorine is a halogen, and forms a negatively charged ionIt has the configuration 1s2, 2s2 2p5It can gain one electron to have a filled p-sublevel and a -1 charge.
Q: im doing a static electricity project and i want to type of cloth has the most positive charge, silk, wool or cotton ? please help
Walk in the morning and eat breakfast within an hour of waking
Q: Are aluminum profiles recyclable multiple times? If yes, explain the process.
<p>Yes, aluminum profiles can be recycled multiple times. The recycling process for aluminum involves melting the scrap aluminum, which requires only 5% of the energy needed to produce new aluminum from raw materials. After collection, aluminum profiles are sorted, cleaned, and shredded into small pieces. These pieces are then melted in a furnace and cast into new ingots or billets. From there, they can be rolled, extruded, or forged into new aluminum products. This cycle can be repeated indefinitely without loss of quality, making aluminum one of the most sustainable materials.</p>
Q: I can't figure out the electron configurations of Aluminum, Argon, or Boron.Any help is appreciated.
Do we really have to answer that question?
Q: When you open an aluminum beverage can, do particles of aluminum get into the drink?
It depends on the type of drink inside the can. Aluminium is a metal in the group three of the periodic table of elements so it has three positive charges when ionized although it has metallic bond between its nucleus and its electrons. If the drink contains too much acid such as HCl with a high concentration the acid may react with the aluminium can if it is not coated or galvanized. Although it may not physically break off for the particles to enter the drink, it may dissolute in the kind of substance inside the drink.
Q: physics question
it helps to maintain an internal tempature and the product will not burn that is why some recipes like turkey will say cook so long covered in foil and cook the last so long to brown the dish .you dont need to use just foil if your pan has a lid and it is oven proof that will work also.it just they use foil because its oven proof.
Q: ive been a coon trapper for 3 years and yet have i found a bait that coon will come to but not possom help me out if trying to get ready for next trapping season i want a bait that only atracts coon and that wont atract possom
It's really not good for youI suggest against itLike, if you have other things you could smoke out of (Bowl, Papers, Pipe, Blunt), I would choose any of those over tin foil or an aluminum canI heard it causes Alzheimer'sIt's really fine every once in awhile but just don't do it like ALL THE TIMEYou'll be fineHope I could help3
Q: The question asks if it's possible to use aluminum strips as flooring material in kitchen or bathroom areas.
<p>Aluminum strips can be used for flooring in kitchens and bathrooms, but they are not the most common choice. They are known for their durability, resistance to moisture, and ease of cleaning, which are desirable traits for these areas. However, they can be slippery when wet, making them a less safe option for bathrooms. They also lack the warmth and comfort of other flooring materials, like tiles or wood. For kitchens, aluminum strips can be a good option for their low maintenance and resistance to spills, but they may not provide the aesthetic appeal that many homeowners desire. It's important to consider the specific needs and preferences of your space when choosing flooring materials.</p>
Q: what recyled things will the garbage ppl take and recyle thme beside paper adn water bottles?
Sometimes, you can take the nut off of the truss rod, and put a shim or washer in there, which may give you a couple more turns, ? You are right in not trying to adjust the neck too far at a time, The guitar has been out of adjustment for so long, means you need to adjust it slowlyI can't help you with the bridge, without seeing the guitar, but a different bridge may help? It may also need a fret level job?
