Hydrogen
Ammonium chloride is formed when ammonia reacts with dilute hydrochloric acid.
When calcium sulphide reacts with hydrochloric acid, it forms calcium chloride and hydrogen sulphide gas. The balanced chemical equation for the reaction is CaS + 2HCl → CaCl2 + H2S. Hydrogen sulphide gas being released gives off a rotten egg smell.
Hydrogen.
Zn + HCl ---> ZnCl2 + H2 ZINC CHLORIDE IS THE ANSWER
Ammonium chloride. This is a CHemical Salt. HCl + NH3 = NH4Cl
Magnesium chloride.MgCl2
No acid is formed. The reaction produces hydrogen gas and magnesium chloride, a salt.
Carbon Dioxide
Iron sulphide and water and carbon dioxide!
Aluminium trichloride (AlCl3) is formed and hydrogen is released.
Any reaction; the solution contain ions: Ca2+ , Cl- , H+ , NO-3.
The salt formed when hydrochloric acid reacts with powdered marble is calcium chloride. The reaction between hydrochloric acid (HCl) and calcium carbonate (found in marble) produces calcium chloride, carbon dioxide gas, and water.
