Calculate the vapor pressure of Hg at 86 oC (in atm). Hg(l) ? Hg(g) ?Ho = 61.32 kJ and ?So = 98.83 J/K
The specific heat of an unknown metal is found to be 0.233 J/K g. The Law of Dulong and Petit predicts a molar heat capacity of 26 J/K mol. Use this law to estimate the molar mass of the metal.
Write a chemical equation for the reaction of an aqueous solution of sodium stearate with each of the following
Write a brief procedure that would have been used to carry out the titration. Just include the key steps (terms and measurements). c. What was the average volume of Ca(OH)2 used? d. Calculate the concentration of the HCI sample.
Draw the crystal field splitting diagram for octahedral Zn^2+ and Ca^2+ complexes. Predict the color of aqueous solutions of Zn^2+ sals and Ca^2+ salts. Does it matter if the complexes are high-spin or low-spin?
The melting of ice requires 1.44 Kcal/mol. If this energy goes into breaking H-bonds, how many H-bonds will there be in liquid water at 0°C?
An evaluation of R was performed, following the procedure described in this module. The barometric pressure was 736 torr, the temperature was 295k and volume of hydrogen gas collected was 35.6 mL. The calculated value of R was 82.1 mL atm K^-1 mol..
