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