Chemical equation for: cuprite, copper(i) oxide chalcocite, copper(i) sulfide covellite, copper(ii) sulfide

Chemical formula for cuprite is Cu₂O. Copper has oxidation number +1 and oxygen has -2 (2·(+1) + (-2) = 0).
Chemical formula for chalcocite is Cu₂S. Copper has oxidation number +1 and sulfur has -2 (2·(+1) + (-2) = 0).
Chemical formula for covellite is CuS. Copper has oxidation number +2 and sulfur has -2.

Ithink the answer is c i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you

If it releases 5 tons a day and there are 7 days a take that answer and multiply by 5 percent (0.05) to find the amount released in one week. leave a comment if you need more .
