give two uses of -:
1) Silicon
2) Antimony
3) Hydrogen
4) Sulphur
5) Chlorine
Answers
Answer:
1)Silicon is one of the most useful elements to mankind. Most is used to make alloys including aluminium-silicon and ferro-silicon (iron-silicon). These are used to make dynamo and transformer plates, engine blocks, cylinder heads and machine tools and to deoxidise steel. Silicon is also used to make silicones.
2)A lead-antimony alloy is used in batteries. Other uses of antimony alloys include type metal (in printing presses), bullets and cable sheathing. Antimony compounds are used to make flame-retardant materials, paints, enamels, glass and pottery. Antimony and many of its compounds are toxic.
3)commercial fixation of nitrogen from the air in the Haber ammonia process.
hydrogenation of fats and oils.
4)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.
5)Chlorine kills bacteria – it is a disinfectant. It is used to treat drinking water and swimming pool water. It is also used to make hundreds of consumer products from paper to paints, and from textiles to insecticides. About 20% of chlorine produced is used to make PVC.
Answer:
1,2,3,4,5 answer in explanation
Explanation:
High-purity silicon is created by thermally 1)decomposing the ultra-pure trichlorosilane. This process is followed by silicon’s recrystallisation, which is used to create many types of electronics, including semiconductors, transistors, printed circuit boards, and integrated circuits.
2)Antimony alloys are also used in batteries, low friction metals, type metal and cable sheathing, among other products.
3)rocket fuel.
welding.
production of hydrochloric acid.
4)Sulfur is used in the vulcanisation of black rubber, as a fungicide and in black gunpowder.
5)Chlorine kills bacteria – it is a disinfectant. It is used to treat drinking water and swimming pool water.
