A student standardizes his NaOH titrant solution with KHP. He performs three titrations - in each trial, the mass of KHP (204.22 g/mol) used is 1.500 g. The average amount of NaOH used in the standardization is 29.3 mL +/- 0.06 mL.
Americium-241 is used in some smoke detectors. It is an alpha emitter with a half-life of 432 years . How long will it take in years for 40.0 % of an Am-241 sample to decay
Determine the total number of valence electrons in each of the following: a) COCl2; b) N2O; c) ClO2^-; d) SeCl2; e) PBr3
Calculate the Z for the fourth ionization of Ti when it requires 425.6 kJ of energy to ionize 0.185 moles of Ti^3+ to Ti^4+ ( The electron being removed is in the outermost valence orbital of Ti^3+ ground state, therefore n = 3)
