1. Determine the wavelength in meters of the line in the spectrum of the hydrogen atom for the transition n=5 to n=1. Does this correspond to emission or absorption?
2. Determine the final volume if 10.0 L methane reacts completely with the 20.0 L oxygen
CH4(g) + 2 O2(g) --->CO2(g) + 2 H2O(l) at100oC and 2 atm?
