Homework Answers
A reducing agent is an element of an electron to another chemical species in a redox chemical reaction. Since the reducing agent is losing electrons, it is said to have been oxidized. Hydrogen donors are also called reducing agents.
Between H2 and H2S bond polarity of H2S is more it is easy to break the bond so it donates hydrogen easily.
Between Mn and Al, Al is more electropositive, less ionization energy of Al easily will give an electron. So stronger reducing agent than Mn.
Mn = [Ar] 3d5 4s2 electron will remove from s orbital so it is difficult to remove than Al where an electron will remove from p orbital
Al [Ne] 2s2 3p1.
