finding expressions for the partial molar volumes at T and P

The molar volume (cm^3 mol^-1) of a binary liquid mixture at T and P is given by: V = 120x1 + 70x2 + (15x1 + 8x2)x1x2 (a) Find expressions for the partial molar volumes of species 1 and 2 at T and P. (e)Plot values of V, partial V1, and partial V2 calculated by the given equation for V and by the equations developed in (a) vs. x ...continues

freezing temperatures of 1.00m solutions of NaCl in water and FeCl3 in water

Are the freezing temperatures of 1.00m solutions of NaCl in water, and FeCl3 in water the same or different. Explain your answer.

Consider the reaction 2(H2O)(l) = 2(H2)(g) + O2 (g)

Consider the reaction : 2(H2O)l = 2(H2)(g) + O2 (g) This reaction has a dispersal of matter since a liquid produces two gases, yet the reaction is not spontaneous. Why is this?

copper Sulfate

As a Env. Biology research project, we were doing toxicity testing and we used copper sulfate as a reducing agent why is this such a good reducing agent. Is there a mechanism that can help to explain this. A part of our final paper is to explain why we chose copper sulfate and not something else, we picked it because when look ...continues
