What does an unexcused absent student receive in a quiz?

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.     

Provide your answers in alphabetical order. Name the three types of tacticities possible in a polyvinyl chloride chain. Spelling must be correct for full credit.

Use the following hypothetical silver (Ag)-iron eutectic phase diagram for a series of fill-in-the-blank questions in Part C2  as well as worksheet problems that you will turn in separately for Part D1 and D2.   

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.

Multiple, multiple choice: The following statement(s) are true of pi bonds.

Provide the weight percentage amount of eutectic solid phase at 400 °C. Round to nearest integer value and be sure to use correct units  where appropriate.

Define the Terms of Gibbs phase rule:  F = C = P =

Provide the composition of the liquid phase at 300 °C. Round to nearest integer value and be sure to use correct units where appropriate.
