A sample of an ideal gas at 0.93atm and 25oC occupied a volume of 17.3L. This gas was transferred to a 3.7L container without a temperature change. What was the pressure of the gas under the new conditions?
What is the balanced net ionic equation for precipitation of CaCO3 when aqueous solutions of Na2CO3 and CaCl2 are mixed
Use the Henderson-Hasselbalch equation to calculate the pH of a 250 mL solution of 0.3 M acetic acid (pKa = 4.76; assume it is initially fully protonated)
How do the enthalpy of dissolution, the crystal lattice energy, and the solvation energy of the two salts relate to these experimental observations?
Calculate the pH change that results when 11 mL of 5.8 M NaOH is added to 800. mL of each the following solutions.
A 0.5220g sample of an unknown monoprotic acid was titrated with 9.96*10^-2 M NaOH. The equivalence point of the titration occurs at 23.84mL.
A solution containing a mixture of metal cations was treated with dilute HCl and a precipitate formed. The solution was filtered and H2S was bubbled through the acidic solution.
if the experimenter uses a thermometer that reads 1.4C too high how will this affect the calculated molar mass.
