What Do We Need to Know Already This chapter develops the ideas in Chapters 9 and 10 and applies them to equilibria involving ions in aqueous solution. To prepare for the sections on titrations, review Section L. For the discussion of solubility equilibria, review Section I. The discussion of Lewis acids and bases in Section 11.13 is based on Section 10.2. 

Remember your audience. Sometimes the object of our description is so clear in our minds we forget that our readers haven t seen it, too. Consequently, the description we write turns out to be vague, bland, or skimpy. Ask yourself about your audience what do they need to know to see this sight as clearly as I do Then fill in your description with ample, precise details that reveal the best picture possible. Don t forget to define or explain any terms you use that may be puzzling to your audience.

What factors can be used to predetermine the quality and utility of a method An analyst must consider the following questions Do I need a proximate analytical method that will determine all the protein, or carbohydrate, or lipid, or nucleic acid in a biological material Or do I need to determine one specific chemical compound among the thousands of compounds found in a food Do I need to determine one or more physical properties of a food How do I obtain a representative sample What size sample should I collect How do I store my samples until analysis What is the precision (reproducibility) and accuracy of the method or what other compounds and conditions could interfere with the analysis How do I determine whether the results are correct, as well as the precision and accuracy of a method How do I know that my standard curves are correct What blanks, controls and internal standards must be used How do I convert instrumental values (such as absorbance) to molar concentrations How many times should I repeat the analysis And how do I report my results with appropriate standard deviation and to the correct number of significant digits Is a rate of change method (i.e., velocity as in enzymatic assays) or a static method (independent of time) needed ...

They had dreamt up this outfit together. Not black, something different, can you do applique Gee you ve got expensive taste. Is it too much of a hassle then No traffic, but it s the feel of it I need to know, the shape. I mean what do you want to look like I don t know. Well, what do you feel like Like an idiot, a fool. I feel like the court jester. And Billy looked through books studied films and ruminated endlessly to finalise a design. Came back from the video shop one night with a medieval drama, she and traffic both leaping up at the entrance of the coxcomb. 

Even when the Fear or Anger types are guilty of denial, they usually have abundant—if incorrect—theories about why they re unhappy. They blame themselves, others, or life itself, but they insist that they know what s wrong. The Self-Deluding type, by contrast, usually has no idea. You tell me, is one of their favorite phrases. What do you think, doctor Lisa asked me, not once but several times. What s my problem What do I need Like most Denial types, hers was not a what-if mind or a judging mind but rather a confused mind, a mind that was either unable or unwilling to face reality. 

Before we look at the results of the survey, I think many of you would enjoy additional background on n to fully appreciate tbe respondents answers. First, ask yourself, what is the importance of knowing the decimal values of Jt Obviously you do not need to know the value of Jt at all to draw a circle, but Jt does appear in many kinds of geometrical engineering calculations. Note that the ancient Greeks and Italians did just fine when the decimal value of jt was known only to a few decimal places. They built perfectly stable, beautiful buildings drew precise circles (Figure 7.1) and made many mathematical discoveries. 

Learning the language of money and finance means you won t be put off or intimidated by the important details of cash flow and balance sheets it means you ll be able to ask critical, informed questions such as when is the business profitable or at what point will the business break even How much do I need to have to be somewhat stress free if the business doesn t make money right away Not knowing how to speak this language makes an entrepreneur feel like a financial cripple. Sure you can function, but you don t have fuU access to all of your potential. 

In the third place, I may be reproached for having given myself useless trouble. For some will say, why do we need to know if this Cassius Longinus has been confused with another, or whether he was capitally punished or merely banished Does the public lose sleep over such things What does it matter if Scaliger was or was not incensed against Erasmus when he considered him as a mere soldier and so on . ..

You would like to determine the pressure drop in a slurry pipeline. To do this, you need to know the rheological properties of the slurry. To evaluate these properties, you test the slurry by pumping it through a 1 in. ID tube that is 10 ft long. You find that it takes a 5 psi pressure drop to produce a flow rate of 100 cm3/s in the tube and that a pressure drop of 10 psi results in a flow rate of 300cm3/s. What can you deduce about the rheological characteristics of the slurry from these data If it is assumed that the slurry can be adequately described by the power law model, what would be the values of the appropriate fluid properties (i.e., the flow index and consistency parameter) for the slurry ... 

I think the fact that I was so doggedly determined—which got me to the top of mountains and through medical school—kept me from doing what I should have done right away, which was to say Even though I don t know what s wrong, I need to get out of this building. 

DR. WILLIAM WOODRUFF (University of Texas) I would like to make a comment not so much on your paper as on mechanistic photochemistry in general. I think most of us would agree that if we are going to draw mechanistic conclusions, we really need to know what the structures of the reactants and products are. One of the problems in photochemistry is that we generally do not know the structure of the reactant, which is the excited state. There aren t very many structure-specific probes in solution, in fact, none below about the millisecond time scale where esr and NMR cease to be applicable. In our laboratory, we have been able to obtain the resonant spectra of excited states. In two of the three kinds of systems that we have observed so far, the structures of the excited states are not predictable in a straightforward way, either from the ground state structures or from calculations.
