Answer:

d . H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O

Explanation:

The given reactions are:

a . 2HgO → 2Hg + O₂,

It is a decomposition reaction, that HgO is decomposed to give Hg and O.

b . Na₂SO₄ + BaCl₂ → BaSO₄ + 2NaCl,

It is a double replacement reaction where two salts replaces their cations and anions with each others producing 2 new salts.

c . Zn + 2AgNO₃ → Zn(NO₃)₂ + 2Ag,

It is a single replacement reaction, that Zn replaces Ag from its salt.

d . H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O

It is acid-base reaction "neutralization reaction" where H₂SO₄ (acid) reacts with KOH (base) producing K₂SO₄ (salt) and water.

So, the right choice is:

A solution of ammonia and water contains 2.60×1025 water molecules and 6.90×1024 ammonia molecules. how many total hydrogen atom

marshall27 [118]

1 molecule of NH3 has 3 atoms of H.
6.90*10²⁴ molecules NH3 have 3*6.90*10²⁴ =20.7*10²⁴ atoms H=2.07*10²⁵ atoms H

1 molecule H2O of has 2 atoms of H.
2.60*10²⁵ molecules of H2O have 2*2.60*10²⁵ =5.20 *10²⁵ atoms of H

2.07*10²⁵ + 5.20 *10²⁵ =7.27*10²⁵ atoms of H altogether.
