Explanation / Answer

Answer:

Question 6

Option d

Neither a nor b is a mineral; however, c is a mineral.

Explanation:

Minerals can't be liquid or gases, they exist only as gases. Ions, charged atoms bond together to form minerals. This formation gives solid structure for minerals.

Question 7:

Option e

Graphite....... carbon
Polymorphs are crystalline minerals those are having the same chemical composition but different molecular packing. This concept is now demonstrated by the different crystalline forms of carbon. So diamond and graphite are all made of pure carbon, but their physical and chemical properties vary drastically.
So each carbon has bonds with more carbon atoms around it than other carbon substances like graphite.

Question 8:

Option b

Garnet

Explanation:
Connecticut is one of the finest sources in the world of the almandine garnet, it named the state mineal by 1977. An ancient gem it was named "garnata"
