Investigating Chemical Equilibrium Date: 30th April 2013 Due Date: 15th May 2013 Prepared For: M. Seraji Prepared by: Andrea Odunze Abstract Many reactions proceed to a state of equilibrium. A chemical reaction at equilibrium‚ where the rates of the forward reaction and reverse reaction are equal‚ looks like this: A + B AB There are three factors‚ according to Le Chatelier’s principle‚ that affect the equilibrium position and equilibrium constant. These are the concentrations of products

“A sense of belonging can emerge from connections with communities and people.” Stella Wu The concepts of belonging are primarily come from attachment with communities and individuals. In the novel “swallow the air” (Tara June Winch 2006) and the movie “Rabbit-Proof Fence” (Phillip Noyce 2002)‚ authors use various language and visual techniques apply to writing and visual cohesion such as symbolism‚ motif‚ quotes and cycle to tell similar story about “the stolen generation”. “Rabbit-Proof Fence”

THE PERIODIC TABLE HISTORICAL BACKGROUND The idea that all things are elements or combinations of elements can be found in the writings of the ancient Greeks and other early peoples. Although this idea may seem simple‚ it is very difficult to decide if a substance is indeed an element or a compound. There were twelve chemical elements discovered in ancient times‚ but it was not known that they were elements. Another 76 elements were discovered between 1557 and 1925. Many mistakes were made in

Curium is highly radioactive. As a metal‚ it is lustrous and silvery. It is malleable‚ chemically reactive and electropositive. Its surface rapidly oxidizes in air‚ gaining a thin film. Most compounds of trivalent curium are stable and faintly yellow or yellow-green. If absorbed in to the body‚ curium accumulates in the bones. Its radiation destroys red blood cell formation. Consequently‚ curium is considered very toxic. Large quantities of curium are now easily made in nuclear reactors. A nuclear

In the first stanza the mirror says that "I am silver and exact"‚ "Whatever I see I swallow immediately / Just as it is". One of the interesting things here is that the mirror is admiring itself‚ praising itself‚ and reflecting itself. The mirror is its own mirror. The second stanza sees a change in the mirror. "I am now a lake". The differences

The earliest known examples of tattoos date back to ancient Egypt. The first tattoo found was from the famous frozen

One variety is Thermate. Thermate burns faster and hotter. Thermate is created by combining thermite‚ sulfur‚ and barium nitrate. The thermate weight ratio is 69% thermite‚ 29% barium nitrate‚ 2% sulfur. There are many other variations of thermite‚ but thermate is the most common alternate form of thermite.
