Which is an example of the kinetic-molecular theory not holding true for a gas? a. the average kinetic energy of particles depends only on the temperature. b. the particles in a gas travel in straight lines in a continuous, random motion. c. the attraction between particles causes a gas to condense at low temperatures. d. the particles in a gas make up a small portion of the total volume of the gas.

Aroller coaster car is traveling down a track at 22 m/s. the car has a mass of 2000 kg. what is the kinetic energy of the car? a) 22,000 j b) 968,000 j c) 484,000 j d) 44,000 j

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1

Particles vibrate in a rigid structure and do not move relative to their neighbors.
