Chapter 11, Problem 3P

One of the most common examples of recursion is an algorithm to calculate the factorial of an integer. The notation n! is used for the factorial of the integer n and is defined as follows:

0! is equal to 1

1! is equal to 1

21 is equal to 2 × 1 = 2

3! is equal to 3 × 2 × 1 = 6

4! is equal to 4 × 3 × 2 × 1 = 24

n! is equal to n × (n - 1) × (n- 2) × … × 3 × 2 × 1

An alternative way to describe the calculation of n! is the recursive formula n × (n−1)!, plus a base case of 0!, which is 1. Write a static method that implements this recursive formula for factorials. Place the method in a test program that allows the user to enter values for n until signaling an end to execution.

Design a schematic for a compartmental model that includes compartments, flows, and parameters with their respective units, using Figure 1 as a guide. For each flow, determine whether it is best represented by a first-order transfer, a Michaelis-Menten saturable process, or a different method.
9. Consider the diagram on the right. Using this diagram and the four following terms: (a) lonization Energy, (b) Electron Affinity, (c) Mulliken Electronegativity, and (d) Polarizability, label each arrow with the correct term (you can label the arrows with the corresponding letter for space purposes). Please provide labels for both species X and Y. lonization Limit b) Indicate why. Energy- Species X Species Y Which species (X or Y) has the highest electronegativity? Which has the largest polarizability? c)( 2) Consider BH3 (boron trihydride) and TIH3 (thallium trihydride). Which one is more polarizable and why? Which one would have stronger intermolecular forces and why?
