3Ca(NO3)2(aq) + 2(NH4)3PO4(aq) ---> 6NH4NO3(aq) + Ca3(PO4)2(s)
Aqueous calcium nitrate plus aqueous ammonium phosphate produces aqueous ammonium nitrate plus solid calcium phosphate.
This is a double replacement reaction.
3Ca+2 + 2PO4-3 --> Ca3(PO4)2
The Balanced reaction equation is 2HCl(aq) + CaCO3(s) = CaCl2(aq) + H2O(l) + CO2(g) Type of reaction is 'neutralisation'. The acid is being neutralised to a salt, water and carbon dioxide. It can also be thought of as an 'Acid + Carbonate' reaction.
2Na3PO4 + 3CaCl2 --> Ca3(PO4)2 + 6NaCl
This is a double replacement reaction which would look like this: 2NH4C2H3O2 + CaSO4 yields (NH4)2SO4 + Ca(C2H3O2)2 so the products are (NH4)2SO4, which is ammonium sulfate, and Ca(C2H3O2)2, which is calcium acetate. These are both soluble in water, so the reaction will reverse itself until it reaches equilibrium, usually indicated by an arrow pointed in either direction in the equation (if you have to balance the equation too).
The chemical equation for the reaction is: (NH4)2CO3 + Ca(NO3)2 → CaCO3 + 2NH4NO3 The precipitate formed is calcium carbonate and it appears as a white precipitate.
Laboratory preparation of ammonia or NH3 requires using ammonium chloride and calcium hydroxide. The reaction equation is 2NH4Cl plus CaOH2 gives the products 2NH3 plus CaCl2 plus 2H2O. The ammonium chloride and calcium hydroxide are heated for this reaction.
- potassium chloride - ammonium and calcium nitrate - ammonium and sodium phosphates - ammonium sulfate etc.

CaNH4(NO3)2
This is a double replacement reaction which would look like this: 2NH4C2H3O2 + CaSO4 yields (NH4)2SO4 + Ca(C2H3O2)2 so the products are (NH4)2SO4, which is ammonium sulfate, and Ca(C2H3O2)2, which is calcium acetate.

3 Ca(OH)2(aq) + 2 (NH4)3PO4(aq) --> Ca3(PO4)2(s) + 6 NH3(g) + 6H2O(l)
The chemical equation for the reaction is: (NH4)2CO3 + Ca(NO3)2 → CaCO3 + 2NH4NO3 The precipitate formed is calcium carbonate and it appears as a white precipitate.
Calcium phosphate is Ca3(PO4)2. It is a combination of the Ca2+ ion with the PO43- ion.
