In which compound have electrons been transferred to the oxygen atom

hloride, what is the mass of calcium in

explanation:

it's filtration, but this is an assumption so my apologies if i got this

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).

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
