Why is butylamine stronger base than ammonia

Kb of butylamine is higher than the Kb of ammonia.

Explanation:

Hello,

In this case, we can cite the methylamine and ethylamine Kb values as 4.38e-4 and 5.6e-4 respectively. On the other hand, ammonia has a Kb of 1.8e-5. Kb is important because it is a measure of how dissociated a base is; now as it is seen, Kb of ammonia is smaller than Kb of both methylamine and ethylamine, it means that the amine are more likely to dissociate, so they are stronger. Nevertheless, since the Kb are given for the aforesaid amines, one expects  the Kb of butylamine to be higher than those. Thus, butylamine is stronger than ammonia in terms of dissociation.

Best regards.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
