Nitrogen and hydrogen combine to form ammonia in the haber process. calculate (in kj/mole) the standard enthalpy change dh° for the reaction written below, using the bond energies given. just enter a number (no units).
n2(g) + 3h2(g) -> 2nh3(g)bond: n≡n h-h n-hbond energy: 945 432 391

increased stability in the completion of fluorine's outer shell.

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.
