How does rate of crystal growth effect the purity of a recrystallized compound? during recrystallization, what effect would impurity have on melting point of benzoic acid?
Explain how rapid crystal growth effects the melting point of the compound. Will it raise or lower the melting point?
1. How does pH specifically affect bacterial growth? 2. How specifically does temperature affect bacterial growth? 3. What terms are used to describe optimum temperature for bacteria? 4. Specifically, how can osmotic pressure affect growth of bacteria? 5. How can anaerobes be grown in the lab? What is the name of the broth? The indicator it contains? 6. Difference between defined and undefined media and understand how media components will support the bacterial growth or not (i.e. fastidious or not)

Aluminum is diffused into a wafer of single crystal high purity silicon at a temperature of 1100°C. Assume that the surface concentration is 1x1018 atoms Al/cm3, and the D- 2x10-12 cm2/s for aluminum diffusing into silicon at 1100°C. (a) On the right, draw a graph showing the aluminum concentration (y-axis) versus depth (x-axis) at an arbitrary time t#0. (1 pt) (b) At 1100°C, how many hours will it take to reach a concentration of 1x1017 atoms Al/cm3 at a depth...
