A Mineral is any occurring, inorganic, crystalline substance ( normally an element or a compound) that possesses a fairly definite chemical composition and a distinctive set of physical properties. They are formed naturally in the Earth, they are usually solid, inorganic, have a crystal structure, and form naturally by geological processes.
Answer:

Hey there!:
HCl + MnO2 → MnCl2 + H2O + Cl2
* in HCl the oxidation state of Cl is -1 .
* on the product side the oxidation state is 0 .
* therefore Cl gains electrons .
* in MnO2 the oxidation state of Mn is +4
* in MnCl2 the oxidation state of Mn is +2
Therefore Mn loses electrons
Answer A
Hope That helps!
To know the answer, you either know what is really the
nature and chemistry of a sugar solution. You can also know the answer by
knowing the meaning of entropy. Entropy is often interpreted as the degree of
disorder or randomness in the system. So the correct statement is that the
system becomes more disordered and has an increase in entropy.
