Suppose a solution at 70 oC (degrees Celsius) contains 50 g NH4Cl/100 g of water. Based on the solubility curve shown here, what additional mass of NH4Cl would be required to saturate the solution at the same temperature? *

If the same amount of cacl2 is added to equal volumes of water and maple syrup, which will have the higher temperature?

Why is the vapor pressure of a warm lake higher than the vapor pressure of a cold lake? o a. warm water has a greater heat of vaporization. ob. warm water evaporates more quickly. cool water evaporates more quickly. od. cool water has a greater heat of vaporization.

How many mmols of tris-hcl are there in 100 ml of a 100 mm tris-hcl buffer solution at ph 8.1? note that the 100 mm refers to the sum of tris and tris-hcl concentrations?
