"Naturally occurring, inorganic substance" factor is not a characteristic of a mineral.
<u>Answer:</u> Option C
<u>Explanation:</u>
A mineral is overall a solid chemical substance that naturally occurs in pure form. Due to the combination of minerals within the rocks, minerals are most strongly associated with rocks.
Substances that exist only in living organisms are generally removed however some minerals are often biogenic like calcite or in the sense of chemistry like mellite are organic compounds. In addition, living creatures also synthesize inorganic minerals like such as hydroxylapatite, which also exist in the rocks.
The correct answer to this question is "5." the oxidation number of cl in ClO3 will be a positive 5 because oxygen is naturally a -2 charge. times that by three and then account for the negative charge of the CLO3- ion.
