Why is aluminium preferred over copper for making a heat cable?
|
|
The difference between aluminum and copper wire is largely in their usage within utilities, resistance, conductivity, weight and cost. Aluminum is in use by the utility companies for the transmission of electricity since the early 1900’s. Aluminum seems to have more advantages over the older copper wire in terms of weight, flexibility and cost, as it is lighter, more flexible, and less expensive.

What happens when iron is placed into aluminium sulphate solution?
|
|
Aluminum sulfate solution has strong acidity. If stainless steel buckets are used for a long time, stainless steel barrels will be corroded. It can be thought that the reaction between stainless steel barrel and aluminum sulfate is chemical reaction.
Hydrolysis of aluminum sulfate can produce sulfuric acid, and sulfuric acid and iron react to form ferrous sulfate, which causes the stainless steel barrel to be corroded.
Al2 (SO4) 3 + 6H2O = 2Al (OH) 3 + 3H2SO4.
Fe + H2SO4 = FeSO4 + H2

What is the chemical formula of aluminum acetate?
|
|
Al(C 2 H 3 O 2 ) 3 - first, aluminium is in the beginning of the equation and acetate needs to be after. Aluminium has a charge of +3 making it Al +3 -acetate has a charge of -1 and its formula is C 2 H 3 O 2 - Using the crossover method, we see that it would take three acetate ions (-1 charge) to balance out the 1 Aluminium Ion (+3 charge). So the final equation should be Al(C 2 H 3 O 2 ) 3

Why doesn't zinc and aluminium rust but corrode instead?
|
|
Passivation refers to the spontaneous formation of an ultrathin film of corrosion products, known as a passive film, on the metal's surface that act as a barrier to further oxidation. The chemical composition and microstructure of a passive film are different from the underlying metal. Typical passive film thickness on aluminium, stainless steels, and alloys is within 10 nanometers. The passive film is different from oxide layers that are formed upon heating and are in the micrometer thickness r

aluminium alloys (or aluminum alloys; see spelling differences) are alloys in which aluminium (Al) is the predominant metal. The typical alloying elements are copper, magnesium, manganese, silicon, tin and zinc. There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable. About 85% of aluminium is used for wrought products, for example rolled plate, foils and extrusions. Cast alu

Oxidation plays a large part. Both iron and aluminum will react with oxygen, but unlike iron, which keeps oxidizing until the whole mass rusts away, aluminum oxides only form on the surface, protecting the rest of metal. A quick coating, like seen on beverage cans, prevents even that. Less oxidized metal means much easier recycling.
Aluminium is extensively recycled because less energy is needed to produce recycled aluminium than to extract aluminium from its ore. Recycling preserves limited

It is soft and malleable. Aluminium is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts. This is because of its particular properties. It has low density, is non-toxic, has a high thermal conductivity, has excellent corrosion resistance and can be easily cast, machined and formed. It is also non-magnetic and non-sparking. It is the second most malleable metal and the sixth most ductile.
It is often used as an alloy because

Aluminum weighs 2.699 gram per cubic centimeter or 2 699 kilogram per cubic meter, i.e. it's density is equal to 2 699 kg/m³. The density was measured at 20°C (68°F or 293.15K) at standard atmospheric pressure. In Imperial or US customary measurement system, the Aluminum density is equal to 168.493065659 pound per cubic foot [lb/ft³], or 1.560120978 ounce per cubic inch [oz/inch³] .

We don’t need to.
Aluminium wasn’t around until the 1800s (late 1800s before it became affordable), but cake was around before that[1] , so they managed to bake cakes without aluminium
We don’t have too but aluminum is the go to for a few reasons.
Unlike glass, aluminum isn’t that heavy and doesn’t break into a billion shards. Metal is also easier to form into the pans we use. I have baked cakes in glass pans before, they can be used but they are bulky and heavy compared to the nice alumi

Pretty straightforward. In general, the reaction of aluminum (Al) and hydrofluoric (HF) produces aluminum fluoride (AlF3) and hydrogen (H2). The balanced equation is:
2Al +6HF → 2AlF3 + 3H2

Papercraft With Aluminium Cans

i wanted to see if papercrafting was possible using aluminium cans (ie. Coke cans), I did a bit of a google around and there doesn't seem to be a lot of information on the subject, so I figured I'd do some research and try a few techniques out to see what I could come up with. I've split this into sections to make it a little easier to read.
