Which item below is an example of a mixture. A) Distilled Water

B) A bottle of hydrogen peroxide h2o2

C) Seawater

D) Liquid CO2

C. sea water

Explanation: basically when you see words that look like someone sneezed and whatever they managed to type (example: Copernicium) just go ahead and eliminate it when it comes to mixtures. Distilled water was there to trick you. Always look for the distilled part, that means it is pure, and therefore not a mixture.

answer: c.

explanation:

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).
