After less than one minute of stirring, a solid should begin to precipitate. After the solid has precipitated, place the flask in ice for 5 minutes. Filter the solid using vacuum filtration. Wash the solid with 20 mL of DI water. Recrystallize from water, as follows. Place the solid in a 250 mL Erlenmeyer flask, add 100 mL of water, boil and keep adding water until the solid dissolves in the boiling solution. Allow to cool on the bench for 10 minutes and place in an ice bath for 15 minutes. Allow to dry for 20 minutes on the Buchner funnel, with the vacuum running. Weigh the crystals.

Question #3 (3 marks) For each of the following, select only one answer. If you believe that more than one answer is correct, select the best answer. A) Considering the two following alternatives to implement semaphores: Test-and-Set and Disable/Enable-Interrupts: i) Enable and Disable interrupts will only work if the system is guaranteed to have a single user. ii) Enable and Disable interrupts will only work if the system is guaranteed to have a single CPU and a single user. iii) Test-and-Set will only work if the system is guaranteed to have more than one CPU. iv) Test-and-Set has a limitation of only implementing binary semaphores on single-CPU systems. v) None of the above answers is correct. B) Considering System Calls and Message Passing, which of the following is correct? i) Systems calls are significantly slower than message passing, but still provide more security. ii) Message passing is both slower and less secure since it requires a separate OS process to be created. iii) Message passing is slower, but it is more secure since the user process does not have access to system space. iv) Message passing is faster than system calls since it does not require a trap and does not require the user process to move to the system space. vi) None of the above answers is correct. C) Considering deadlock, which of the following is correct? i) It is not possible to have deadlock if the system is a single-user system. ii) It is not possible to have deadlock in a uni-programming system that has only one CPU. iii) It is not possible to have deadlock in multi-programming system that has only one CPU iv) It is not possible to have deadlock in multi-programming system that has mire than one CPU. v) Two of the above answers are correct.
