The reaction AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq) is a

reaction. please help

it's a precipitation reaction.

Explanation:

the solid produced is insoluble with water–making it a precipitate.

the product of the pressure and volume is also constant

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).
