Answers
Answer:
Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.
boiling the pieces of ore are used for detecting 20th species of human life due to the following reasons:
- In the earth's crust cobalt is found only in chemically combined form as it is a chemical element.
- The atomic number of cobalt is 27 and its symbol is co.
- To examine manners and machinations of cellular reproduction cytologic methods are used.
- In alloys of natural meteoric iron found the ore cobalt which is saved for small deposits.
- A silver-grey metal is produced which is hard,lustrous and has a reductive smelting produces a free element.
