    chemical resistance of materials

    Regarding Gd(NO3)3, I see that the electronegativity and 1st ionization potential of Gd is along the same lines as Al, which readily forms hydroxides and oxides. For Gd, then, you could look at the worst case scenario (assuming aqueous solvent), which would be full dissociation of Gd(NO3)3. The...

    Need phase diagram

    The phase diagram for n-butane can be calculated via the extended Antoine equation, using the parameters below: Antoine equation: Log10(P)=(A)+(B/T)+(C)Log10(T)+(DT)+(ET^2) Where A = 2.7044E+01 B = -1.9049E+03 C = -7.1805E+00 D = -6.6845E-11 E = 4.2190E-06 T = temperature in ºK. These...
