Given the balanced equation representing a reaction:
nh3(g) + h2o(l) ==> nh4+(aq) + oh-(aq)
according to one acid-base theory, the nh3(g) molecules act as
(1) an acid because they accept h+ ions
(2) an acid because they donate h+ ions
(3) a base because they accept h+ ions
(4) a base because they donate h+ ions
