The species: `H_(2)O, HCO_(3)^(Θ), HSO_(4)^(Θ)` and `NH_(3)` can act both as Bronsted acids and bases. For each case give the corresponding conjugate acid and base.

Explanation

The answer is given in the following Table:
`{:("Species","Conjuglate","Conjugate"),(,"acid","base"),(H_(2)O,H_(3)O^(-),OH^(-)),(HCO_(3)^(-),H_(2)CO_(3),CO_(3)^(2-)),(HSO_(4)^(-),H_(2)SO_(4),SO_(4)^(2-)),(NH_(3),NH_(4)^(+),NH_(2)^(-)):}`
