Find the enthalpy of hydration for an iodide ion in the process Rbl > Rb+ +|-. Use AHsol = - Hat+ Hnyde AHsol = 31.0 kJ/mol
AHiat = -630.0 kJ/mol
AHhydr of Rb+= -315.0 kJ/mol
--661.0 kJ/mol
0-661 kJ/mol
–284.0 kJ/mol
0-284 kJ/mol

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

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.
