Ammonium nitrate (nh4no3) dissolves readily in water even though the dissolution is endothermic by 26.4 kj/mol. the solution process is spontaneous because

In this given scenario, ammonium nitrate dissolves readily in water even though the dissolution is endothermic. The solution process is spontaneous because of the increase of the disorder upon dissolution of this strong electrolyte. In addition, the ions are much more stable in a solution to the extent that ambient heat will be absorbed to complete the process.

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.
