Balance the equation and answer in terms of moles.Chlorine gas can be produced commercially by passing an electric current through a concentrated solution of sodium chloride (brine).
A student wants to prepare a dilute solution of iron (III) solution, . The student is provided with a stock solution of 0.800 +/- 0.001 M and a 100.00 +/- 0.008 mL volume trick flask since the experiment trquires about 80 mL of the dilute iron (II..
Predicting the Polarizability of a Molecule. Consider the following set of data for polarizability. From what I have learned, the simplest model for predicting the polarizability of a molecule is to assume that polarizability scales with the type.
