A: Atoms and molecules is the correct answer.
Answer:
Ammonia is a weak electrolyte, weak base.
Option e.
Explanation:
Ammonia can take a proton from water to make ammonium.
It is a base, because it takes proton.
When a compound can take protons, we know that is base, according to Bronsted Lowry theory.
We can't describe ammonia as a base, according to Arrhenius, but we know it is base according to Lewis, because the N from the ammonia can be a donor of its electron pair.
It is weak because an small amount of ammonia, can react to produce ammonium, between the protons of water. This is the equilibrium, where the ammonia is considered as the conjugate strong acid of ammonia.
NH₃ + H₂O ⇄ NH₄⁺ + OH⁻ Kb
All the amines are considered as weak bases, because they look like ammonia, where the H of NH₃ are replaced by others chains.
------NH₂
-----NH-----
18 I think. <span>Essentially because there are so many more orbitals used by the molecules placed in the series. You will see that group 1-8 molecules always have a number of valence electrons equal to the group number. This reflects s and p orbital useage. Once d and f orbitals begin to be needed, the atoms become much more complex.</span>
B,because it seems like the most active answer outta the rest
false, if you are saying that there is only one single atom of water.
