WebJan 17, 2024 · Mass of Hydrogen chloride : 4.672 g Further explanation Given Reaction Fe + 2HCl ⇒ FeCl2 + H2 3.56 g of Iron Required mass of Hydrogen chloride Solution mol of Iron (Ar = 56 g/mol) : mol = mass : Ar mol = 3.56 : 56 mol = 0.064 mol HCl from the equation : = 2/1 x mol Fe = 2/1 x 0.064 = 0.128 Mass HCl : =mol x MW HCl = 0.128 x 36.5 = 4.672 g WebAnswer: Fe (II) or Ferrous compounds are readily formed as the 2nd ionization energy is considerably less as compared to the third ionization energy. The amount of energy required to remove the third electron from Iron is as much as the energy to make it Fe²⁺. Also Fe²⁺ forms fairly stable compo...
