Two different gases are stored in separate closed containers. If both gases have a temperature of 50°C, which statement is true?
The thermal energies of gas molecules in the two containers are unrelated.
The gas molecules in both containers will absorb heat from the surroundings.
The molecules in one gas will transfer energy to the molecules in the other gas.
The gas molecules in both containers have the same average kinetic energy.

Determine the wavelength of the light absorbed when an electron in a hydrogen atom makes a transition from an orbital in the n=3 level to an orbital in the n=7 level.

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
