Nitric acid (hno3) and ammonia (nh3) react to form ammonium nitrate (nh4no3), which is classified as a salt an acid a base

Ammonium nitrate is a salt.

NH₃  + HNO₃ ⟶ NH₄NO₃

base +  acid    ⟶   salt

When an acid and a base neutralize each other, they form a salt.

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).
