The catalysts used in this process are platinum or vanadium pentoxide (V 2 O 5 ) that are heated to a high temperature. The optimum temperature required is 450 - 500 o C. Remember:- Low temperature favours the oxidation of sulphur dioxide. If the temp..

Lithium tarnishes slowly in moist air while dry air has no effect. When heated in air or oxygen at about 200C, it burns with a brilliant white light forming lithium monoxide. ..

Oxygen is very essential for the existence of human life on Earth. It is the most abundant element on the surface of the Earth. In a free state, it is present in the Earth's atmosphere to an extent of about 21% by volume, (23.15% by mass) In the combined form, it constitutes about 88% by ..
