Using your worksheet for Part D1, draw and label the phase(s) present in each circle for the alloy compositions given (9, 25, and 85 wt% Fe) at particular temperatures (500, 400, and 300 °C).  Assume equilibrium conditions have been met. Do not calculate the amount(s) of phases, but be sure to clearly indicate any differences in the amount of each phase at the different temperatures where relevant.     

Write your entire answer to this question in Part D3 of your worksheet that you will submit separately.  (a) Using 3D drawings, show how electrons move between 4 vinyl chloride monomers to form one isotactic polyvinylchloride chain. Assume that 1 electron is provided by the initiator species and one electron from a hydrogen atom is provided by the solvent.  (b) Circle all the new covalent bonds in the polymer chain product. (c) Write the chemical notation for your isotactic polyvinylchloride chain from (a) that includes the repeat unit.
