Question

Write a balanced half-reaction for the reduction of gaseous nitrogen N2 to aqueous hydrazine N2H4 in acidic aqueous solution. Be sure to add physical state symbols where appropriate.

Answer 1

Step-by-step explanation:

N₂ (g ) + 4H⁺( aq ) + 4e⁻ = N₂H₄ ( aq )

H⁺ ion comes from acidic medium . 4 positive charge on proton is balanced by 4 electron to make left hand side neutral because right hand side is neutral .
