Consider the reversible reaction: 2NO2(g)?N2O4(g)^-1 If the concentrations of both NO2 and N2O4 are 0.016 mol • L , what is the value of Qc? The answer is supposed to be 63 but how and why?
Evaluate the energy of an electron excited from a hydrogen atom using Bohr's model. Determine the maximum wavelength of energy needed to observe a photoelectric effect for potassium.
Why does this calculation only provide an estimate of the NaOH concentration. In other words, why do we have to standardize the HaOH in this experiment to find its exact concentration
