What is the pH at the first equivalence point in the titration of a 100.0 mL sample of 0.075 M nicotine ($C_{10}H_{14}N_2$, $pK_{b1}$ = 6.00, $pK_{b2}$ = 11.00) with 0.150 M HCl? Equivalence point: moles of acid = initial moles of base Moles of nicotine: 0.075 M x 0.100 L = 0.0075 moles
Question 4 6 pts A paged memory is shared by two processes, p1 and p2. The memory is shown in the figure below: 5 3 3 2 0 1 2 3 1 3 1 5 3 2 -4 5 8 Page table 1 3 1 2 Page table 6 2 8 of p1 1 4 2 4 of p2 1 5 2 3 The size of each page and page table is 4. The page table of p1 begins at address 4. The page table of p2 begins at address 12. A dash (-) denotes a nonexistent page number, and a number denotes a non-resident page. Fill up the blanks in the table below. For each process, translate the virtual addresses into the corresponding physical addresses. If the translation is successful, read the content of the corresponding memory location and write down the number in the blank. Otherwise, indicate whether a page fault or an error has occurred by writing down "PF" exactly as "P" followed by "F" in the blank. Virtual address in decimal Access by p1 Access by p2 11
