Our world today is characterized by efficiency from minor things to making coffee in the morning to determining the most effective and aerodynamic structure for a common day fuselage. Now imagine our world‚ one that strives for efficiency‚ without Internet. I wouldn’t guarantee that efficiency would overcome simplicity in a world where communication is scarce and a source of information is uncommon. The dilemma at our hand is that people do not acknowledge the fact that even though the Internet might

Explain why negative externalities are an example of market failure? Market failure refers to the failure of the market to allocate resources efficiently. Market failure results in allocative inefficiency‚ where too much or too little of goods or services are produced and consumed from the point of view of what is socially most desirable. Hence when there are negative externalities caused during consumption and production‚ this causes a welfare loss further more causing market failure. Negative

Documentary films and their representations of the Holocaust have served not only to speak their truth’ of the atrocities but also to document changing paradigms of social thought concerning Holocaust truth’. Holocaust History and its documentation: Theodor Adorno’s famous 1949 injunction that to write poetry after Auschwitz is barbaric’ is indicative of the initial approaches of documentary to the subject matter. The first documentary footage of the Holocaust was shot as Allied troops

specified chemical reaction occur?” o Many thermodynamically favourable reactions are so slow (ex: metamorphic transformation of rocks‚ corrosion of marble sculptures owing to weathering) that they can be considered not to happen! Derivation of equilibrium constant (gases) Consider the following reaction‚ where reactants (A‚ B) and products (C‚ D) are all gases: ?? ? + ?? ? → ?? ? + ?? ? (where ?‚ ?‚ ?‚ ? are stoichiometric coefficients) The change in molar Gibbs free energy of that reaction: ∆? = ??

ACIDS AND BASES The reason that acid-base reactions are so important is that many of the things you come into contact with on a daily basis are either acids or bases. Most fruits are acids‚ as are carbonated beverages‚ tea‚ and battery acid. Common household bases include baking soda‚ ammonia‚ soap‚ and antacids. What are acids and bases? There are not one but three common definitions used to describe acids and bases: 1. Arrhenius acids and bases 2. Brønsted-Lowry acids and bases 3. Lewis acids

has a force constant of 850 N/m. A block of mass 1.00 kg is attached to the spring and oscillates freely on a horizontal‚ frictionless surface as in Active Figure 5.20. The initial goal of this problem is to find the velocity at the equilibrium point after the block is released. (a) What objects constitute the system‚ and through what forces do they interact? (b) What are the two points of interest? (c ) Find the energy stored in the spring when the mass passes through the equilibrium and again when

HX is a weak acid -In every acid-base reaction‚ equilibrium favors transfer of the proton from the stronger acid to the stronger base to form the weaker acid and the weaker base. -Kc (equilibrium constant) 1 (right) Know that water auto-ionizes into hydrogen ions and hydroxide ions‚ expressed by Kw‚ the ion product of water. - Kw=[H3O+][OH-]
