use the balmer's equation to determine : (a) the frequency in per second of the radiation corresponding to n=5.
10) the wavelength in nanometers of the line in the balmer series corresponding to n=7. (c) the value of n
corresponding to the balmer series line at 380 nm

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)
