Key feature of a Bronsted Lowry base : The notable feature of all bronsted lowry bases is that they contain atleast one electron lone pair, which is available for interaction with a proton, and allows the base to act as a proton acceptor.
<h3>What do we know about Bronsted Lowry Base?</h3>
Any species that can receive a proton and needs one pair of electrons to attach to the H+ is referred to as a Bronsted-Lowry base. Since water is amphoteric, it may function as both a Brnsted-Lowry acid and a base.
The Brønsted–Lowry theory is an acid–base reaction theory which was proposed independently by Johannes Nicolaus Brønsted and Thomas Martin Lowry in 1923.

Answer:
Explanation:
Given reaction
N₂H₄ + O₂ ⇒ N₂ + 2H₂O ΔH₁ = -543 KJ ---------- ( 1 )
2H₂ + O₂ ⇒ 2H₂O ΔH₂ = -484 KJ ---------- ( 2 )
N₂ + 3 H₂ ⇒ 2NH₃ ΔH₃ = -92 KJ -----------( 3 )
( 1 ) - ( 2 ) +( 3 )
N₂H₄ + O₂ - 2H₂ - O₂ +N₂ + 3 H₂ ⇒ N₂ + 2H₂O - 2H₂O +2NH₃
ΔH = -543 + 484 -92 = -151 KJ
N₂H₄ + H₂ ⇒ 2NH₃ ΔH = -151 KJ .
2NH₃ ⇒ N₂H₄ + H₂ ΔH = + 151 KJ
