acid base interaction?

Question

in each of the following define the acid base interaction:
H3O+ (aq) + OH- (aq) --> 2H2O (l)

BF3(g) + NH3 (g) --> F3B - NH3 (s)

Answer 1

The first is an Arhennius acid-base reaction, in which a hydronium ion acid reacts with hydroxide base to form water.

The second is a Lewis acid-base reaction, in which electron-acceptor BF3 acid reacts with electron-donor NH3 base to form F3B<-NH3.
