(a) Using data in Appendix C, estimate the temperature at which the free-energy change for the transformation from I2(s) to I2(g) is zero.What assumptions must you make in arriving at this estimate?
(b) Use a reference source, such as Web Elements (www.webelements.com), to find the experimental melting and boiling points of I2.
(c) Which of the values in part (b) is closer to the value you obtained in part (a)? Can you explain why this is so?
A molecule, whose formula is AB, dissolves in water and also conducts electricity. What one statement best describes this molecule after it's placed in water
A voltaic cell is constructed by immersing a strip of silver metal in a 1.0 M AgNO3 solution and a strip of cadmium metal in a 1.0 Cd(NO3)2 solution. The circuit is completed by a wire and a salt bridge in the usual way.
