Chapter 2, Problem 3E

Write a program that demonstrates the operator % by performing the following tasks:

  • Use scanner to read a floating-point value x.
  • Compute x % 2.0 and store the result in y.
  • Display x and y clearly labeled.
  • Type cast x to an int value and store the result in z.
  • Display x, z, and z % 2 clearly labeled.

Try your program with positive and negative values of x. What implications do your results have for deciding whether a negative integer is odd?

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?
