Question

pls answer with full explaintion​

Answer 1

Answer:

(1) MnO2 + HCl → MnCl2 + H2O + Cl2

The balanced chemical equation is

MnO2 + 4 HCl → MnCl2 + 2H2O + Cl 2

By means of a stoichiometry, 1 mol of manganese dioxide reacts with 4 mol of HCl (hydrochloric acid) to form 1 mol manganese chloride 1 mol of chloride & 2 mol of water.
