Question

boiling the pices of ore used to detect 20th species of human life​

Answer 1

Answer:

Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation). Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks,[4][5] and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere.

Answer 2

Question :

Bring the pieces that are used to detect the 20th species of human life ?

Answer :

The fossil pieces are used to detect the 20 species of human life.

• A fossil is defined as any kind of preserved impression or remains from the period of geological age. Some of the examples are shells, bones, skulls, some of the imprints of animals, etc.

• The study of fossils is known as paleontology. The specimens with 10,000 years old is said to be fossils. The oldest fossils are 3.48 billion years old.

• The exact number of early human species is not known. Yet the detection of species can be done by analyzing the fossils.
