What else can I help you with?
Which the most abundant metal in the Earth crust?
Depends. What do you consider a metal?If you're an astronomer, it's oxygen. Chemists will laugh at you for saying this, but astronomers (well, some astronomers) divide the elements into "hydrogen, helium, and everything else, which for short we'll call 'metals'". On the cosmological scale, there's some justification for this, as hydrogen and helium are a lot more abundant in the universe as a whole than anything else.Even if we exclude oxygen as a clear non-metal (in chemical terms), the next most abundant element is silicon, and it's possible to get into all kinds of arguments over whether silicon is a "metal" or not.The next one after silicon is aluminium, and most people would agree that aluminium is a metal, though a few might quibble and say it's really a metalloid/semi-metal along with silicon.After that comes iron, which is the most abundant element in the crust where no one can reasonably make a case that it's anything but a metal.
Why aluminium is cheaper to extract than gold even though the extraction method is more complicated?
Bauxite ore is the base for aluminium and is more plentiful than gold ore. It is also cheaper to polish to the finished product. Aluminium has many more uses than gold so is readily adaptable to the consumer market. by Ruwayda :)
Which natural process can change the earths surface though glaciers wind and flooding?
Mudslides
What type of plastic are wheelie bins made from?
High density polyethylene, though some bins are made from recycled plastics.
Why does weight on an elevator change though you don't leave earths gravity?
If the elevator accelerates, the acceleration will provide an additional apparent force.
Can Aluminium can be recycled this makes it a sustainable material?
Aluminium is the worlds most abundant metallic element in the earths crust, and can be recycled without degradation of properties though some is lost. Aluminium's high scrap value and well established recycling infrastructure make it the most frequently recycled metal, so much that 73% of the aluminium ever produced is still in use today. Recycling is not a perfect process and ultimately it will be all used.
How can supplies of metals such as copper and aluminum remain healthy even though there is a dwindling amount in the earths crust?
They can be recycled.
Why is iron cheaper thatn aluminum even though it is more abundant?
Even though Aluminium is more abundant than iron, the reduction of alumina to produce aluminium requires a huge amount of energy making chemical reduction extremely difficult and as a result, expensive. Source: Chemistry for WA 1 Stage 2AB Cherie Lewis and Peter Lewis
What is the chemical formula for aluminum hydrogen?
Sorry there is no such compound as aluminium hydrogen though there is aluminium hydride - AlH3 or if that isn't it aluminium hydroxide - Al(OH)3

Why is aluminium can be used outdoors even though it is quiet high in the reactivity series?
Aluminium forms a thin, protective oxide layer on its surface when exposed to oxygen, which helps prevent further corrosion. This oxide layer makes aluminium highly resistant to corrosion, allowing it to be used outdoors even though it is high in the reactivity series.

What percent of rubbish is recycled?
In many states, about 35% of rubbish is recycled. The number is climbing every year, though, as companies find ways to recycle.
How many times can cardboard be recycled?
There is no limit on the number of times cardboard can be recycled. Cardboard will lose it's integrity as it is continuously recycled though.
Has anyone ever purchased recycled glass countertops?
recycled glass countertops can be pricey even though they are recycled, they are still glass. they offer a lot of color but if they do chip or crack they cannot be easily fixed and must be replaced.
What is the most abundant metal in earth?
Aluminum is the most abundant metallic element on Earth. It makes up more than eight percent of the earth's crust. Though, it is never free in nature. It combines with oxygen, sand, iron and titanium, and its ores are mainly bauxites.
What will happen to a compass needle when an aluminium bar is kept in between them?
The compass needle will be unaffected by the presence of the aluminium bar as it is not magnetic. Aluminium is not a magnetic material, so it will not interfere with the function of the compass needle.
