As you have it written NH3 donates a proton to the solution and this hydrogen ion is picked up by PH3 to make PH4; so NH3 is the acid here. ( though this reaction seems odd to me )
M+M+NH+V+C+RI=NEMaine + Massachusetts + New Hampshire + Vermont + Connecticut + Rhode Island = New England
The sum of adding 4 to itself 23 times is 96. This can be calculated by multiplying 4 by 24, as each addition of 4 counts as one less than the total number of 4s being added. Therefore, 4 x 24 equals 96.
