Which chemical is the reducing agent in the redox reaction below?
zn(s)
fe2+(aq)
zn2+(aq)
fe(s)

The reducing agent is the element that gets oxidized. Therefore, Zn(s) is the correct choice. It goes from 0 charge to 2+

its going to be mutualism cuz they both benefit from the relationship.

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).
