Answer 1

Question options: a. have a crystal structure b. has an unpredictable chemical structure c. can be liquid or solid d. can be organic or inorganic .

Answer:

options (a) and (c) applies

Explanation:

• Minerals usually have a definite crystalline structure, however this is not always the case, as some naturally occurring minerals are not crystal like.

• the chemical structure of minerals are predictable.

• Minerals can only exist as solids. if any substance is in its liquid form then its not a mineral.

• finally minerals can either be inorganic or organic.Inorganic minerals do not contain carbon, while organic minerals are made up of carbon

Answer 2

Minerals are solid, naturally occurring, inorganic compounds that possess an orderly internal structure and a regular chemical composition. Minerals should occur naturally. Hope this answers the question. Have a nice day. Feel free to ask more questions.
