Hints for problems

PROBLEM 3.48 Find all the isomers of the formula C4H5CI. As in Problem 3.46, it is easiest to divide this problem into sections. First, find the degrees of unsaturation so that you know what types of molecule to examine. There are 23 isomers to find. Hint. See the hint for Problem 3.47. 

Nitraminothiazole. treated for 12 hr with 96% sulfuric acid, gives 2-amino-5-nitrothiazole (194). The mechanism of this rearrangement is not yet quite resolved even for nitraminobenzene derivatives (617). The series of kinetic determinations and appropriate labeling performed by Toth et al. provide, however, precious hints for this difficult problem (1578. 1579). 

Use the algebraic procedure to synthesize an MEN which has the minimum number of units satisfying the MOC solution for Problem 3.4. Hint Due to the absence of a pinch, there is no need to examine the matching feasibility criteria given by Eqs. (5.8) and (5.12). All you need is to check the practical feasibility Eq. (3.5) at the two ends of each exchanger. 

HINT This problem is very lengthy if done just by trial and error - for example, the value of z on halting can be f x) for n > 30. It may help first to notice that it suffices to consider interpretations I with domain the integers, 1(f)(n) = n+1, and initial input x = 0 and then... 

Problem 5-13. Verify that if A = I, then Ax Ay = x y for any vectors x and y. Why does this imply that the transformation represented by the matrix A does not alter lengths and angles (Hint see problem 5. )... 

Monod kinetics are often a better description of the reactions occurring in sediment. Assume that the flux conditions are similar to problem 2 for SOD. The maximum bacterial growth rate is 0.5 hr in these sediments, and the halfsaturation coefficient is 1 g/m of oxygen. What is the microbacterial population for the 0.5- and 5-g/m -day cases (Hint, use a change of variables to solve for / = dCIdz.) Plot oxygen concentration for each case on the same scale as for problem 2 and compare the two plots. 

Derive the concentration profile for problem 2, except with as a function of z. Plot the concentration profile on the same plot. What accounts for the difference Hint Set C = Co at z = 1 mm, then determine Co value that results in the given mean suspended concentration. 

Q, R O, N. The second letter goes forward in the alphabet starting at D and skipping every other letter. The third letter starts at J and goes forward in the alphabet. Hint For these types of problems write down the complete alphabet A through Z and look for patterns. 

The book is designed to introduce even a beginner to the whole extent of the problems, to acquaint him with all types of derivatives and methods employed, and to enable him to utilize them in practice without it being necessary to consult the original sources to this end full descriptions of the main procedures are provided. However, it is intended that workers proficient in the field will also find the book to be a source of useful information, and perhaps, inspiration. This intention is supported by the inclusion of some of the latest publications and a chapter on identification and quantitation, which may give hints for further investigations.

Obtain an analytical solution for problem 7 using a similarity solution technique. Hint define w = u/x and derive an equation for w. Define X = x - R and solve for w as a function of X ant t.
