Determine the molarity of a saturated aqueous solution of NaI formed as 25degree celsius assuming that the added NaI does not add significantly to the volume of the water?
A sample that weighs 0.1586 grams contains only sodium chloride and potassium chloride was dissolved in water. It took 22.90 mL of 0.1000 AgNO3 to precipitate all of the chloride present.
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.
Compute the value of ΔH ° if the combustion products are CO2 (g) and H2O (g). it isgiven that: CO 2 (g) = ΔHf ° - 393.5 kJmol-1; H 2 O (l) = ΔHf ° -285.8 kJmol-1; H 2 O (g) = ΔHf ° -241.8 kJmol -1.
