chromium (cr) can combine with chlorine (cl2) to form chromium chloride (crcl3). which equation is a correct representation of this reaction?
a. cr + cl2→ crcl3
b. 2cr + cl2→crcl3
c. 2cr + 3cl2→crcl3
d. 2cr + 3cl2→ 2crcl3

I would go with A.

hope this helps!

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).
