Hydrogen
CaS + 2HCl --> H2S + CaCl2
Hydrogen.
Ammonium CHLORIDE, NH4Cl
Carbon Dioxide
Iron sulphide and water and carbon dioxide!
Aluminium trichloride (AlCl3) is formed and hydrogen is released.
hydrochloric acid reacts with iron when it starts bubbling , magnesium reacts more though .
No acid is formed. The reaction produces hydrogen gas and magnesium chloride, a salt.
salt and water
Zn + HCl ---> ZnCl2 + H2 ZINC CHLORIDE IS THE ANSWER
Zinc.
A gas H2S evolves.
