Consider the potassium permanganate reaction again. 2kmno4 16hcl → 2kcl 2mncl2 8h2o 5cl2 how many moles of water are produced when 3.45 moles of kmno4 react? give your answer to the nearest 0.1 moles.

Respuesta :

13.8 moles H2O. hope it helps

Answer;

= 13.8 moles

Explanation and solution;

  • The equation for the reaction is;

16HCl + 2KMnO4  ------> 2KCl + 2MnCl2 + 5Cl2 + 8H2O

  • The equation is balanced and gives proper stoichiometry. This is a redox reaction involving HCl and KMnO4.
  • According to stoichiometry of the reaction 2 moles of KMnO4 will produce 8 moles of H2O.
  • That means 1 mol of KMnO4 will produce exactly 4 moles of H2O  (since 8/2 = 4).
  • Therefore, 3.45 moles of KMnO4, will produce;

          3.45 moles × 4  = 13.8 moles

Hence, when 3.45 moles of KMnO4 react, 13.8 moles of water will be produced.
