Under what conditions was the maximum amount of precipitate formed when the copper sulfate was added to the zinc sulfide?

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

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).

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
