Explain the numbers of grams of the zinc sulfide
Determine the numbers of grams of the zinc sulfide should precipitate the theoretically if 2 liters of a 4 M aqueous solution of zinc nitrate are reacted with an excess of an aqueous solution of sodium sulfide. Zn(NO3)2 + Na2S = 2NaNO3 + ZnS

Calculate the rotational theta temperature for HCl? Calculate the rotational partition function at this temperature by using the classical approximation and rigid rotor model.
Why the temperature would be required to achieve a population of the first excited vibration state of that is 1/2 the population of the ground state?
Determine the population ratio N(v=1)/N(v=0), where v=0 and 1 are the ground and excited vibration states for the HCl at room temperature of 298K? Assume a vibration transition wave number of 2991 cm-1 and Cl-35isotope.
