The right answer for this problem

(a)  When aqueous solution of hydrochloric and ammonia chemically react together then it results in the formation of ammonium chloride.

The reaction equation for this reaction is as follows.

Now, ioni equation for this reaction is as follows.

Cancelling the spectator ions, the net ionic reaction equation is as follows.

(b)   When sodium hydroxide chemically reacts with ammonium chloride then it forms ammonia, water and sodium chloride as follows.

Now, the total ionic equation will be as follows.

Cancelling the spectator ions from the above equation. Then the net ionic equation will be as follows.

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).

is there any options? maybe im just not seeing them but i need the options to
