What is enough

Even without the added impetus of these special circumstances, parental investment in the only child is always at some risk of creating high expectations and demands that can drive the only child to extremes in response. He or she can become continually troubled by mulling over endless variations of that agonizing question " What is enough "... 

What these well-meaning parents don t understand, however, is that their primary source of influence is not through what they say, but by what they modelby who and how they are. They instruct by example. The only child learns to strive for extremes from parents who are driven by their own excessive responses to variations of the same vexing question "What is enough "... 

If ever tiiere were an extremely emotional and volatile subject, money is it. So where do we begin with such an emotional subjed as this Start by becoming dear, crystal dear about what is enough for you. How much do you need to make you authentically happy to the bones I think it s really important to ask yourself this question before you attempt to jump-start your business. If you already have a business, take the time now to discover and articulate this for yourself. How do you define success Why is having... 

Possible water sources for injection are sea water, fresh surface water, produced water or aquifer water (not from the producing reservoir). Once it has been established that there is enough water to meet demand (not an issue in the case of sea water), it is important to determine what type of treatment is required to make the water suitable for injection. This is investigated by performing laboratory tests on representative water samples. 

Information about critical points on the PES is useful in building up a picture of what is important in a particular reaction. In some cases, usually themially activated processes, it may even be enough to describe the mechanism behind a reaction. However, for many real systems dynamical effects will be important, and the MEP may be misleading. This is particularly true in non-adiabatic systems, where quantum mechanical effects play a large role. For example, the spread of energies in an excited wavepacket may mean that the system finds an intersection away from the minimum energy point, and crosses there. It is for this reason that molecular dynamics is also required for a full characterization of the system of interest. 

Enough of the arguments, let s take a look at what Is going on here. 

Some people think that 48% aq, HBr is good enough and, until recently, some underground chemistry texts agreed. But it is not The 48% is only strong enough to promote what is called acid catalyzed hydration (don t ask) when the medium it is in is water. That means that a water molecule (an OH) will add instead of a Br. 

Solvent Effects on the Rate of Substitution by the S 2 Mechanism Polar solvents are required m typical bimolecular substitutions because ionic substances such as the sodium and potassium salts cited earlier m Table 8 1 are not sufficiently soluble m nonpolar solvents to give a high enough concentration of the nucleophile to allow the reaction to occur at a rapid rate Other than the requirement that the solvent be polar enough to dis solve ionic compounds however the effect of solvent polarity on the rate of 8 2 reactions IS small What is most important is whether or not the polar solvent is protic or aprotic Water (HOH) alcohols (ROH) and carboxylic acids (RCO2H) are classified as polar protic solvents they all have OH groups that allow them to form hydrogen bonds... 

The equilibrium constant for an acid-base indicator is determined by preparing three solutions, each of which has a total indicator concentration of 1.35 X lQ-5 M. The pH of the first solution is adjusted until it is acidic enough to ensure that only the acid form of the indicator is present, yielding an absorbance of 0.673. The absorbance of the second solution, whose pH was adjusted to give only the base form of the indicator, was measured at 0.118. The pH of the third solution was adjusted to 4.17 and had an absorbance of 0.439. What is the acidity constant for the acid-base indicator ... 

Until now we have been purposely vague about the quantity Aw. Since we shall use the notation of Eq. (8.42) from now on, it is convenient to say a few more things about Aw before we lose sight of it entirely. Reaction (8.A) is clear enough what is unspecific are the conditions under which this reaction takes place. Several possibilities come to mind, and each imparts a slightly different meaning to the energy w ... 

Nickel and other transition metals function as solvent-catalysts for the transformation of carbon species into the diamond aHotrope. At temperatures high enough to melt the metal or metal—carbon mixture and at pressures high enough for diamond to be stable, diamond forms by what is probably an electronic mechanism (see Carbon, diamond-synthetic). 

To see what is going on physically, it is easier to return to our first condition. At low stress, if we make a little neck, the material in the neck will work-harden and will be able to carry the extra stress it has to stand because of its smaller area load will therefore be continuous, and the material will be stable. At high stress, the rate of workhardening is less as the true stress-true strain curve shows i.e. the slope of the o/e curve is less. Eventually, we reach a point at which, when we make a neck, the workhardening is only just enough to stand the extra stress. This is the point of necking, with... 

But what is the proper way to use toughness values The most sensible thing to do is ask suppose the panel is loaded up to its yield load (above this load we knoiu it will begin to fail - by plastic flow - so it does not matter whether other failure mechanisms also appear) what is the maximum crack size that is still stable If this is large enough... 

Certainly a thermodynamically stable oxide layer is more likely to generate passivity. However, the existence of the metastable passive state implies that an oxide him may (and in many cases does) still form in solutions in which the oxides are very soluble. This occurs for example, on nickel, aluminium and stainless steel, although the passive corrosion rate in some systems can be quite high. What is required for passivity is the rapid formation of the oxide him and its slow dissolution, or at least the slow dissolution of metal ions through the him. The potential must, of course be high enough for oxide formation to be thermodynamically possible. With these criteria, it is easily understood that a low passive current density requires a low conductivity of ions (but not necessarily of electrons) within the oxide. 

In many ways, the title of this section is the central question that those with a predilection for toying with fundamental issues eventually find themselves asking. It is also a question that (not unlike the problem of formulating a legitimate - or even an allowable - question about what is really going on in quantum mechanics), must be asked correctly. It is not enough merely to rusk the que.stion in its simplest form. We must first of all be sure of what we are asking. 

The diene must adopt what is called an s-cis conformation, meaning "cis-like" about the single bond, to undergo a Diels-Alder reaction. Only in the s-cis conformation are carbons 1 and 4 of the diene close enough to react through a cyclic transition state. In the alternative s-trans conformation, the ends of the diene partner are too far apart to overlap with the dienophile p orbitals. 

Nickel reacts with sulfur to form a sulfide. If 2.986 g of nickel reacts with enough sulfur to form 5.433 g of nickel sulfide, what is the simplest formula of the sulfide Name the sulfide. 

Insulin is a hormone responsible for the regulation of glucose levels in the blood. An aqueous solution of insulin has an osmotic pressure of 2.5 mm Hg at 25°C. It is prepared by dissolving 0.100 g of insulin in enough water to make 125 mL of solution. What is the molar mass of insulin ...
