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.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
