Answer:CaCO3+ 2HCl➡️Cacl2+CO2+H2O
2. 2Al+6HCl➡️2AlCl3+3H2
3. MnO2+ 4HCl➡️MnCl2+Cl2+2H2O
Explanation:
Here in First reaction one molecule of CaCO3 reacts with two molecules of HCl. Ca gets attached to Cl to form CaCl2 and two molecules of Hydrogen gets attached to one molecule of Oxygen to form H2O finally remaining CO2 gas gets evolved.
