Write the equilibrium constant expression for this reaction: CH3OH (aq)+Cl-(aq)-> CH3Cl(aq)+OH-(aq)

clouds form

solid ice forms on leaves.

water droplets form on grass.

a:

by the combination of an unlimited number of elements

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
