In the Week 2 lab, we determined the partition coefficients of
benzoic acid between the binary solvent systems CH2Cl2 / H2O and
CH2Cl2 / (10% NaHCO3). a. Explain why the observed partition
coefficient for CH2Cl2 / H2O is greater than for CH2Cl2 / (10%
NaHCO3). b. Compared to CH2Cl2 / H2O, what change would you expect
to see in the partition coefficient for benzoic acid if 1M HCl were
used as the aqueous solvent? What about 1M NaOH? Why
1. Find the number of unique addresses accessed by a 16-bit
microprocessor. If the width of the data bus is also 8 bits,
determine the word size in bytes.
2. What is the difference between DRAM and SRAM in terms of
their applications? Why do synchronous DRAMs make use of a
register, called a mode register?
Find the number of r-permutations of the multiset
{∞?1, ∞?2, … , ∞??} such that in
every such permutation each type of an element of the multiset
appears at least
once. (You do not need to provide a short answer. Assume r ≥
n.)
2. Answer the following question
(a) Write a Java program to find the number of integers within
the range of two specified numbers and that are divisible by
another number. For example, x = 5, y=20 and p =3, find the number
of integers within the range [x, y] and that are divisible by
p.
(b) Write explicitly on the following OOP concepts:
i. Encapsulation
ii. Inheritance
iii. Polymorphism
(c) Develop a Java application that computes the two roots of...
