...In the phonology of stress-timed languages, the weak form of a word is a form that may be used when the word has no stress, and which is phonemically distinct from the strong form, used when the word is stressed. The strong form serves as the citation form. A weak form is a word as an unstressed syllable, and is therefore distinct from a clitic form, which is a word fused with an adjacent word, as in Italian mangiarla, 'to-eat-it'. A word may have multiple weak forms, or none. In some contexts, the strong form may be used even where the word is unstressed. Read full entry

Why does a salt containing a Please explain!

OK, let's call the salt AB. That's because the acid and base that formed the salt were HA and BOH. We're told that BOH is weak, but HA is strong. That is, HA doesn't exist in water; it all dissociates into H+ and A-. But BOH exists at equilibrium in water; some dissociates, but not all. And since equilibria work in both directions, when you put a bunch of B+ in the water, some BOH will form. So when you put the salt into solution, it first dissociates into A- and B+ ions. The A- ions don't do anything, because HA is strong. But the B+ ions form some BOH by taking OH- anions from the water around them. Of course, this means that some H+ cations, which were attached to the OH- anions, are now floating freely around the solution, making it acidic. |

2. Which of the following a.Semistrong-form market
efficiency implies that as
soon as any public or private
information comes into being
it is incorporated into stock
prices.
b.Weak-form market efficiency
implies that recent trends in
stock prices are of no use in
predicting future stock
prices.
c.Market efficiency implies
that all stocks should have
the same expected return.
d.According to strong-form
market efficiency, insiders
would find it possible to
consistently earn abnormal
returns in the stock market
even if they have superior
knowledge about the company.
e.Studies of the Efficient
Markets Hypothesis suggest
that neither the weak-form nor
the semi-strong forms of
efficiency hold, especially
for larger companies. However,
the market appears to be
strong-form efficient because
institutional traders make
abnormal profits.

EMH comes in 3 forms: 1) Weak form:Past price history is of little use in earning excess profits. 2) Semi-strong: Past history and fundamental public info is of little use in earning excess profits. 3) Strong: Even inside, non-public information is of little use in earning excess profits. Therefor: a) False-Private non-public info is useful under semi-strong. b) True c) False-Depends on risk of individual security d) False-Even insiders should not earn abnormal, superior, or excess returns e) False-Under strong form, traders should not earn abnormal profits. B is the only Correct statement |

___ are weak bonds that are but are strong enough to form
bridges between molecules
a. ionic bonds
b. covalent bonds
c. polar covalent bonds
d. hydrogen bonds
e. anionic bonds

Answer: Hydrogen bonds: They form when there is a dipole-dipole force between a hydrogen bond donor and a hydrogen bond acceptor. Hydrogen bonds are weaker then all of the bond mentioned above. Edit: I'm not sure what anionic bonds are either, however I know that hydrogen bonds do not form molecules. They can join molecules together, like water, but they are not strong enough to hold atoms together. Hydrogen bonds are not as stable, and generally do not last long. They are always breaking and reforming. |
