Calculate the freezing point of a 2 molal solution of a nonelectrolyte glucose. feezing point constant for water being 1.86 C/molal
Halogenated compounds are mainly easy to identify by their mass spectra because chlorine as well as bromine occur naturally as mixtures of two abundant isotopes. Chlorine takes place as 35Cl (75.8%) and 37Cl (24.2%); bromine occurs as79Br (50.7%) ..
Show that the Slater determinant formalism automatically incorporates the Pauli exclusion principle by evaluating the He ground-state wave function of Equation 10.8, giving both electrons the same quantum numbers.
