(3 pts) If 13.219 g ammonium perchlorate is added to a 500.00 mL solution of 0.375 M ammonia, which of these statements is true? You may assume addition of the salt does not change the volume. the pH increases because perchlorate is a weak base the pH remains constant because ammonia is a strong base the pH decreases because ammonium is a weak acid

Isolated system A has non-degenerate single particle quantum energy levels of energy 0, 2, 4, 6, 8, 10 energy units and consists of one red particle of spin zero having an energy of 6 energy units. Isolated system B has non-degenerate single particle quantum energy levels of energy 0, 1, 2, 3 ... 10 energy units, and consists of two non-interacting particles of spin zero, coloured white and blue respectively. The total energy of the white and the blue particles is 2 energy units. List the microstates accessible to each isolated system. The two systems are placed in thermal contact. What is the number of microstates accessible to the composite system? What is the increase in entropy? Calculate the ensemble averages of the energies of both systems after they are placed in thermal contact. Repeat the calculations for the case when the particles are identical bosons of spin zero.

4-(25) Trace Figure 2.4 (attached) and find L, R, C, and D for the next round using the following information: The message length is 8 bits: 10101011 The Key is 6 bits: 101010 The (Permuted Choice 2) is implemented by means of concatenating two of its inputs. The E-table is implemented by adding 2 bits (10) to the right side of the processed message (part of the message at this point). The S-box is implemented by means of removing 2 bit from the left side of the processed message. The permutation (P) is implemented by taking 2's complement of the message received from the S-box.
