Answer:
oxygen atoms gain electrons and hydrogen atoms lose electron
Explanation:
Hydrogen oxygen fuel cell involves redox reactions.
It is an electrochemical cell, which is used for many applications like rocket propellant.
The actual reaction is
Here hydrogen undergoes oxidation as it loses electrons
Oxygen undergoes reduction as it gains electrons.
The redox reactions are
At anode:
[loss of electrons by hydrogen]
At cathode:
[gain of electrons by oxygen]
The reaction of sodium sulfide with hydrogen sulfide can be shown as
Sodium hydroxide is completely reacting and thus act as limiting reactant
Thus, 2.31 g Na2S produced.
