Because it will react with the ammonia, CaCl2 being a weak acid, pKa about 8, which is somewhat stronger than ammonium, pKa(NH4+) = 9.24.

Why can't metals that are high on the activity series like calcium be precipitated from aqueous solution?
because they cant
Does sodium chloride has strongest or weakest molecular forces?
You cant say that it's strongest nor weakest but it is pn the strong side:)
Can you make meth with urea cold packs instead of ammonia nitrate?
no you cant. your thinking of the shake n bake one pot method and one has to use amonia nitrate, not urea.
Why cant Calcium Carbonate CaCO4 conduct electriscity when mixed with de-ionized water?
Because CaCO4 is molecular, it does not ionize in water. Thus, the water remains without electrolytes and cannot provide a path for current to flow.
What can peolpe do to prevent getting injured during an earthquake?
you cant you cant
Does calcium corrode?
yes
Atomic number for ammonia?
Ammonia is a compound. We cant give a atomic number.
Why cant other alkali metals be substituted?
Alkali metal atoms can often be substituted by other atoms under the right conditions An example is Caesium in Caesium Chloride. By heating Caesium chloride with Calcium metal, caesium is substituted by calcium and the caesium can be distilled off at about 700oC under vacuum. This seems surprising, particularly given the higher reactivity of caesium, but the greater lattice energy of calcium chloride makes this the energetically preferred product over caesium chloride and drives the reaction. (As an aside, this was the most terrifying reaction that I ever did in a lab because of the high temperature caesium that is produced...)
Can humans live without calcium in their body?
no they cant calcium is what keeps are bones strong
Is ammonia a acid base or is it neutral?
Usually ammonia is basic. It cant be neutral or acidic.
Why does ammonia hydroxide not react with calcium?
I'm not the best at chemistry just thought i would try to help. anyways I'm pretty sure its to do with how ammonia hydroxide cant break down the calcium for it to react. Full marks for trying. However, permit me to supply something a bit closer to the mark. ===================== I do not think the questioner has that question right. Ammonium hydroxide would react strongly with calcium, which is a reactive metal that bubbles hydrogen in contact with water. If you put some calcium metal in with ammonium hydroxide, it would immediately give off bubbles of hydrogen, and produce calcium hydroxide, releasing ammonia gas. I suppose that the question you really want to ask has something to do with why a dilute calcium hydroxide does not release ammonia from ammonium compounds. If that is what you want to know, the answer might be something like that calcium hydroxide is a weak base, too weak to displace the ammonium and produce ammonium hydroxide. I have my doubts though; that does not make much sense. I think you had better put more preparation into your homework. You cannot get anywhere in chemistry without taking trouble to understand it.
Why cant liquid ammonia conduct electricity unlike aqueous ammonia?
In liquid NH3 there are zero ions to 'transport' charge. In ammonia (NH3 solution in water) there are some (1%) positve NH4+ and negative OH- ions to do so.
What molecules does calcium carbonate have?
Calcium Carbon and Oxygen, CaCO(4)Wait I Searched It Up and I Cant Find Any Information?
Why ammonia gas cannot be dried by using conc.H2SO4 AND P2O5?
sulphuric and P2O5 are acidic. So you cant do that because of ammonia is basic.
Which gas cannot be dehydrated using sulphuric acid?
Ammonia cant be as it would react - neither can phosphine
How do you separate crack from cocaine with ammonia?
technicaally u cant but u can definitly turn cocain into crack
Why cant magnesium chloride be separated from its crystalline form by just heating it?
The energy you're putting in by heating is less than the energy that holds the Magnesium to the chloride ion.
