Organic chemistry is the study of essentially all substances containing carbon. Organic compounds that contain only carbon and hydrogen are called hydrocarbons. The simplest hydrocarbons are the alkanes which contain only single covalent bonds. Methane is the simplest alkane. It is also the major component of natural gas. Methane contains only 1 carbon in the molecular formula and the structural formula. There is ethane which is 2 carbons‚ propane that is 3‚ butane which is 4‚ pentane which is 5

ANALYSIS Not marble‚ nor the gilded monuments (1): This line is likely an allusion to the lavish tombs of English royalty; in particular‚ to the tomb of Henry VII in Westminster Abbey‚ which contains a large sarcophagus made of black marble with gilded effigies of King Henry and his queen‚ Elizabeth of York. unswept (4): note that the pronunciation here is /UN swept/. with sluttish time (4): i.e.‚ by filthy time. In Elizabethan England the word "sluttish" could describe either a sexually promiscuous

Exchange Principle states‚ “Any action of an individual‚ and obviously the violent action constituting a crime‚ cannot occur without leaving a trace.” It is hard to say Locard’s Exchange Principle was not disregarded. After three months of expert investigation it was found that the DNA evidence that was discovered at the scene did not belong to Jennifer or Noura. Also Noura’s own DNA was not found at all at the scene of the crime. It is very hard to understand how Noura could have made extreme violent

Separation of a Carboxylic Acid from a Neutral Compound by Extraction Reference: Smith‚ Chapter 2 (Acids and Bases) Introduction Carboxylic acids and phenols are two families of organic compounds that contain carbon‚ hydrogen and oxygen‚ and also react with water to yield an excess of hydronium ions over hydroxide ions. Pure water has a pH of 7‚ which means it has a hydronium ion concentration‚ [H3O+] of 10-7 M (M = molarity‚ moles/Liter). The hydronium ions in pure water come from the self-ionization

Questions 1. Compare and contrast acids and bases in terms of their H+ ion and OH-ion concentrations. When an acid is dissolved in water‚ there are more hydrogen ions(H+) present than hydroxyl ions(OH-) due to the fact that acids donate hydrogen ions. An alkaline or basic solution accepts hydrogen ions. As a result‚ it has more hydroxyl ions in solution. Using the pH scale‚ pure water is neutral with a pH of 7. Acids range from 1-6‚ with the strongest acid having a pH of 1. Alkaline substances

Between 1801 and 1805 Lord Elgin‚ from the Parthenon in Athens‚ obtained the Elgin Marbles‚ which consists of pieces of architecture‚ sculptures‚ and inscriptions. The Elgin Marbles can be found in the British Museum‚ which allow people to understand ancient Greek and Athenian history. Since the sculptures are one of the longest cultural rows in Europe‚ the Greeks want the art to be returned back to their homeland. Because the Greeks believe that the pieces were illegally taken from Greece. On the
