A bicycle tire contains nitrogen, oxygen, and argon gases.If the partial pressures are 48.0 , 14.5 , and 0.4 , what is the total pressure (in atm)?
Describe why this is based on the wavelength range that is transmitted. What color would you see if you mixed the two solutions with ?max = 520 and ?max = 610?
Calculate the nonstandard emf for each of the following reactions if the concentration of each of the ions in these reactions is 0.0004 molar and everything else is standard (use 298 K for the temperature, R = 8.314 J/mol-K, and F = 96,485 C/mol)
