Question

Most minerals on earth surface contain which of the following:

A:Nitrogen and oxygen
B:Oxygen and silicon
C:Silicon and nitogen
D:Sulfur and hydrogen

Answer 1

Answer: The correct answer is option (B).

Step-by-step explanation:

The minerals are natural occurring inorganic solids with fixed chemical compositions with constituent atoms placed in an orderly pattern.

90% of earth crust is composed of a mineral made up silicates. And these silicates are the chemical compounds made up of silicon and oxygen element. They are also known as silicon tetra-oxide with chemical formula of
`SiO_4`.

Hence, the correct answer is option (B).

Answer 2

Correct answer choice is :

B) Oxygen and silicon

Step-by-step explanation:

Silicates comprise silicon molecules and oxygen atoms. One silicon atom is bonded to four oxygen atoms. These atoms form a tetrahedron. The silica tetrahedron is the raising block of silicate crystals. This performs silicon more or less still to more oxidation by air even up to about 900°C. After this, reaction with oxygen in the air produces silicon dioxide. At temperatures above about 1400°C, silicon responds with nitrogen, N2, in the air as well as oxygen, to make the silicon nitrides SiN and Si3N4.
