Write the use of following:
a) Platinum
b) Graphite
c) Sulphur
d) Phosphorus
e) Aluminium
Answers
a)Platinum is widely used as a catalyst for chemical reactions. The most important use of platinum is in vehicles, as a catalytic converter, facilitating the complete combustion of unburned hydrocarbon passing through the exhaust.
b)Graphite is used in pencils and lubricants. It is a good conductor of heat and electricity. Its high conductivity makes it useful in electronic products such as electrodes, batteries, and solar panels.
c)Elemental sulfur is used in black gunpowder, matches, and fireworks; in the vulcanization of rubber; as a fungicide, insecticide, and fumigant; in the manufacture of phosphate fertilizers; and in the treatment of certain skin diseases. The principal use of sulfur, however, is in the preparation of its compounds.
d)Phosphorus is a vital plant nutrient and its main use – via phosphate compounds – is in the production of fertilizers. ... Phosphorus is used in the manufacture of safety matches (red phosphorus), pyrotechnics and incendiary shells. Phosphorus is also used in steel manufacture and in the production of phosphor bronze.
e)Aluminium is a silvery-white, lightweight metal. 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.

Platinum
●● Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry.
Graphite
●● Graphite is used in pencils and lubricants. It is a good conductor of heat and electricity. Its high conductivity makes it useful in electronic products such as electrodes, batteries, and solar panels.
Sulphur
●● Sulfur is used in the vulcanisation of black rubber, as a fungicide and in black gunpowder.
Phosphorus
●● Phosphorus is a vital plant nutrient and its main use – via phosphate compounds – is in the production of fertilizers. Just as there are biological carbon and nitrogen cycles, there is also a phosphorus cycle. Phosphorus is used in the manufacture of safety matches (red phosphorus), pyrotechnics and incendiary shells.
Aluminium
●● 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
