Explore the conditions under which the 'integral' approximation for the translational partition function is not valid by considering the translational partition function of an H atom in a one-dimensional box of side comparable to that of a typical nanoparticle, 100nm. Estimate the temperature at which, according to the integral approximation, q = 10 and evaluate the exact partition function at that temperature.
A 0.8102g sample of impure Al2(CO3)3 decomposed by HCl; liberated CO2 was collected on CaO and found to weigh 0.0515g. Compute the percentage of Al in the sample.
