Please help I need to get this done!! D: Identify the substance oxidized, the substance reduced, and, if any, spectator ions.
Cl2 (aq) + 2KI (aq) → I2 (s) + 2KCl (aq)
Oxidation:
Reduction:
Spectator Ions:

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

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).

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a
