A 0.100 M M solution of ethylamine (C2H5NH2 C 2 H 5 N H 2 ) has a pH p H of 11.87. Calculate the Kb for ethylamine

i believe a. 12x≥120 is the answer

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.

wait this depends wether emily and zach how they are thinking.

yes they are the same.
