Magnetite, an iron ore, can be reduced to form metallic iron by a process called pyrometallurgy. Determine how much iron would be produced from 5 grams of iron oxide. (you must balance first) Fe3O4 + CO → Fe + CO2

answer is a

explanation:

b. examine and describe cells

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).
