Question

Возможна реакция между хлоридом аммония и гидроксидом кальция сульфатом натрия и соляной кислотой хлоридом меди (II) и ртутью

Answer 1

Единственная тут проходящая реакция - хлорид аммония и гидроксид кальция (причем эта реакция может происходить даже при простом смешивании твердых веществ):
2NH4Cl + Ca(OH)2 = CaCl2 + 2H2O + 2NH3

Answer 2

Reaction between Ammonium Chloride and Calcium Hydroxide

The reaction between ammonium chloride (NH4Cl) and calcium hydroxide (Ca(OH)2) can result in the formation of ammonia gas (NH3), water (H2O), and calcium chloride (CaCl2).

The balanced chemical equation for this reaction is as follows: 2NH4Cl + Ca(OH)2 → 2NH3 + 2H2O + CaCl2

Reaction between Sodium Sulfate and Hydrochloric Acid

The reaction between sodium sulfate (Na2SO4) and hydrochloric acid (HCl) can produce sodium chloride (NaCl) and sulfuric acid (H2SO4).

The balanced chemical equation for this reaction is as follows: Na2SO4 + 2HCl → 2NaCl + H2SO4

Reaction between Copper(II) Chloride and Mercury

The reaction between copper(II) chloride (CuCl2) and mercury (Hg) can result in the formation of copper(I) chloride (CuCl) and mercury(II) chloride (HgCl2).

The balanced chemical equation for this reaction is as follows: CuCl2 + Hg → CuCl + HgCl2
