Which base nh4oh or ba(oh)2 required more h2so4 to reach neutralization ?

Ba(OH)₂ requires more H₂SO₄ to reach neutralization..

Explanation:

2NH₄OH + H₂SO₄ → (NH₄)₂SO₄ + 2H₂O.

It is clear that every 2 mol of NH₄OH need 1 mol of H₂SO₄ to be neutralized.

Ba(OH)₂ + H₂SO₄ → BaSO₄ + 2H₂O.

It is clear that every 1 mol of NH₄OH needs 1 mol of H₂SO₄ to be neutralized.

So, Ba(OH)₂ requires more H₂SO₄ to reach neutralization.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
