Kendall · Answer 1

b. Si c. O (SiO 2)

Explanation:

This mineral is commonly found in earth's minerals which include quartz, feldspar, mica, pyroxene, and olivine, etc. Since the Silica tetrahedra, made up of silicon and oxygen they share the common bond Silica makes 95% of the earth's mantle crust and 97% of the terrestrial crust. A variety of silicate minerals are found in the environment like silicon atom. A Simple silicate atom includes the Fe iron and Mg elements. When silicate anions combine, they share oxygen ions and hence the formation of the tetrahedral sheet is commonly formed.

Jessie Cummings · Answer 2

c. O

Explanation:

Silicate minerals -

The rocks made up of silicate groups are called the silicate minerals. Around 90% of the Earth's crust have silicate minerals.

The structure of silicate minerals, is the small tetrahedral silica are joined via oxygen atom to make - up the rock.

Hence, from the given options, the correct is c. O.
