In the following reactions (i) MnO 2   +   4 HCl → and (ii) 2 KMnO 4   +   16 HCl → , the number of moles of chlorine gas released respectively are

Step-by-step solution

(i) MnO 2   reacts with the four moles of hydrochloric acid and formed one mole of the MnCl 2 and one mole of chlorine and two mole of water. Reaction :- MnO 2   +   4 HCl → MnCl 2   + Cl 2 + 2 H 2 O (ii) Two mole of potassium permagnate reacts with the sixteen mole of hydrochloric acid and formed the two mole of MnCl 2 and two moles of potassium chloride and five moles of chlorine gas and eight moles of water. 2 KMnO 4   +   16 HCl → 2 MnCl 2   + 5 Cl 2 + 8 H 2 O + 2
