Conclusions, writing

Drawing Conclusions Write statements that summarize the results of the lab activity. 

Drawing a Conclusion Write a balanced equation for the reaction that took place as the club soda was heated. 

Drawing a Conclusion Write a word chemical equation to describe what happened during the hydrolysis of starch. 

Most publications require an informative abstract for every paper, even if they do not publish abstracts. For a research paper, briefly state the problem or the purpose of the research, indicate the theoretical or experimental plan used, summarize the principal findings, and point out major conclusions. Include chemical safety information when applicable. Do not supplement or evaluate the conclusions in the abstract. For a review paper, the abstract describes the topic, scope, sources reviewed, and conclusions. Write the abstract last to be sure that it accurately reflects the content of the paper. 

Decide udiether you think each statement is true or false. Discuss the reasons why you think so and write it all down. If someone disagrees with your conclusion, write down the reasons why. 

Conclusion Write full formulations of all the reactions that occurred... 

Although there is no rehable method as of this writing for induction of Ag-speciftc unresponsiveness, some degree of tolerance has been observed by use of nonspecific immunosuppressive therapy. This conclusion is supported by a decrease in the frequency of precursor T-ceUs reactive with graft HLA Ags in long-term recipients of organ transplants. 

Analysis of Data. A veteran practitioner of chemical market research likened this step to the assembly of a jigsaw puzzle. There are many pieces of unequal size and importance that must be put together to make a picture understandable to everyone. Call reports, secondary data inputs, experience, and judgment are the tools used by the market researcher to analyze the data, reach conclusions, make recommendations, and write the report. 

AletabolicFunctions. The chlorides are essential in the homeostatic processes maintaining fluid volume, osmotic pressure, and acid—base equihbria (11). Most chloride is present in body fluids a Htde is in bone salts. Chloride is the principal anion accompanying Na" in the extracellular fluid. Less than 15 wt % of the CF is associated with K" in the intracellular fluid. Chloride passively and freely diffuses between intra- and extracellular fluids through the cell membrane. If chloride diffuses freely, but most CF remains in the extracellular fluid, it follows that there is some restriction on the diffusion of phosphate. As of this writing (ca 1994), the nature of this restriction has not been conclusively estabUshed. There may be a transport device (60), or cell membranes may not be very permeable to phosphate ions minimising the loss of HPO from intracellular fluid (61). 

Following the classification of Chapter 4.01, three classes will be considered, (a) Compounds isomeric with aromatic compounds (6), (7) and (8). The quaternary, non-aromatic salts (Scheme 7, Chapter 4.01) will be discussed only in connection with protonation studies which lead to the conclusion of their non-existence. The carbonyl derivatives (9), (10), (13) and (14) will also be included here because it is possible to write an aromatic tautomer for each one, (9 )-(14 ), even if it is energetically unfavoured, (b) Dihydro compounds. In this class not only pyrazolines (15), (16) and (17) but also pyrazolidinones (18) and pyrazolinediones like (1) are included, (c) Tetrahydro compounds. Besides the pyrazolidines (19), the pyrazolidinetriones (2) are included here. 

In conclusion of this section, we write out the expressions for the density matrix of a free particle and a harmonic oscillator. In the former case p(x, x P) is a Gaussian with the half-width equal to the thermal de Broglie wavelength... 

Photolysis of bicyclo[2.2.2]octan-2-one (A) gives B in good yield. When A labeled as shown is used, the aldehyde group carries deuterium to the extent of 51.7%. Write a mechanism to account for the overall transformation. Calculate the isotope effeet for the step in which hydrogen-atom transfer occurs. What mechanistic conclusion do you... 

Display and examine electrostatic potential maps for ethyl cation, 2-propyl cation and 2-methyl-2-propyl cation. Which cation shows the greatest localization of positive charge If you find that the methyl groups delocalize the positive charge, where does the charge go Write resonance contributors for the three cations to rationalize your conclusion. (Note You may need to draw resonance contributors that contain a CC double bond and are missing a CH bond see also Chapter 7, Problem 8.)... 

To take this idea seriously would require that we abandon the familiar table of isolated atoms and begin to think about how to set up a table of bonded atoms of the elements. Schwarz does not actually carry out this further step in his own writing. In my own paper, which is reproduced in this collection, I try to build such a table and quickly arrive at the conclusion that the idea is un-workable since it cannot be carried out categorically. 

And Maher goes on explicitly to underline the conclusions about confirmatory weight that he sees as illustrated by this episode. He claims that Mendeleev s prediction of the existence of the third of the new elements, eka-silicon (aka germanium), was initially regarded as quite unlikely to be true but then later, with the discovery of the first two new elements (gallium and scandium), confidence in the prediction of the existence of the third new element became so high that its eventual empirical confirmation was widely regarded as a matter of course. Maher writes ... 

Comparison of this result with equation (6.30) leads to the conclusion that AxSxi and Sx- j are, except for a multiplicative constant, the same function. We implicitly assume here that Sxi is uniquely determined by only two parameters, X and 1. Accordingly, we may write... 

The conventional view of depression is that it is caused by a chemical imbalance in the brain. The basis for this idea was the belief that antidepressant drugs were effective treatments. Our analyses showing that most - if not all - of the effects of these medications are really placebo effects challenges this widespread view of depression. In Chapter 41 examine the chemical-imbalance theory. You may be surprised to leam that it is actually a rather controversial theory and that there is not much scientific evidence to support it. While writing this chapter I came to an even stronger conclusion. It is not just that there is not much supportive evidence rather, there is a ton of data indicating that the chem-... 

Much of what 1 write in this book will seem controversial, but it is all thoroughly grounded on scientific evidence - evidence that I describe in detail in this book. Furthermore, as controversial as my conclusions seem, there has been a growing acceptance of them. NICE has acknowledged the failure of antidepressant treatment to provide clinically meaningful benefits to most depressed patients the UK government has instituted plans for providing alternative treatments and neuroscientists have noted the inability of the chemical-imbalance theory to explain depression.6 We seem to be on the cusp of a revolution in the way we understand and treat depression. 

The photochemistry of octacyanometallates, and of mixed cyano-dii-mine complexes of the type [W(CN)6(diimine)]2 and [MO(CN)3(bpy)] M = Mo, W, has been reviewed (183). The authors pay particular attention to the role of the counterion in this type of reaction they also call attention to questions which were, at the time of writing, unresolved. A mainly structural and redox review of octacyano-, nitridotetracyano-, and oxotetracyano-metallates (Nb, Ta Mo, W Tc, Re) contains some kinetic and mechanistic information on thermal and photochemical substitution in these complexes, with the main conclusion being that much more needs to be done on such reactions (184).
