Why is iron more reactive than copper? Why is it important to keep the developing chamber covered with plastic wrap during the development of the chromatogram? Why does electroplating take place on the cathode and electrorefining take place on the anode?
Despite the fact that aluminium is a reactive metal, it is a stable in air as well as in water. This is due to the formation of thin layer of oxide on the surface of aluminium metal which makes it passive for further attack. The layer is so useful, that in industry, it is purposely...
this thirteenth element of the Periodic Table is called Aluminium. Whereas, Aluminum is the preferred spelling in American and Canadian English. It is no wonder, as there are more than 4000 words in the English language
AIt is less reactive than alkyl halides BIt can be oxidised to benzaldehyde by boiling with copper nitrate solution . CIt is a lachrymatory liquid and answers Beilstein s test DIt gives a white precipitate with alcoholic silver nitrate Which of the following statements about aluminium chloride is ...
If a piece of aluminium consists of 6.02*10^{23} atoms, how much does it weigh? What is a supernova? What is decay theory? Convert 1.75 grams to kilograms. What are gamma rays? Is the atom the smallest part of matter? A particular radioactive isotope has a half-life of 200 years....
The water, caustic S and other ash components absorb microwave radiations more readily than other constituents. Microwave treatments (Al-Harahsheh and Kingman2004) have also been used in the extraction of metals such as copper, gold, nickel, cobalt, lead, zinc and manganese and coal desulfuris...
Aluminium Copper Copper is an important metal and does not occur in nature in its pure form. It has excellent heat conductivity. Copper reacts with the oxygen present in the air and thus further leads to corrosion. It turns green in colour and stops corroding further. It is reddish in colo...
