Empirical formula

In chemistry, the empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound. A simple example of this concept is that the empirical formula of sulfur monoxide, or SO, would be SO, as is the empirical formula of disulfur dioxide, S2O2. Thus, sulfur monoxide and disulfur dioxide, both compounds of sulphur and oxygen, have the same empirical formula. However, their molecular formulas, which express the number of atoms in each molecule of a chemical compound, are not the same. An empirical formula makes no mention of the number of atoms, it is standard for many ionic compounds, like calcium chloride, for macromolecules, such as silicon dioxide. The molecular formula, on the other hand, shows the number of each type of atom in a molecule; the structural formula shows the arrangement of the molecule. It is possible for different types of compounds to have equal empirical formulas. Samples are analyzed in specific elemental analysis tests to determine what percent of a particular element the sample is composed of.

Glucose, acetic acid, formaldehyde all have different molecular formulas but the same empirical formula: CH2O. This is the actual molecular formula for formaldehyde, but acetic acid has double the number of atoms, ribose has five times the number of atoms, glucose has six times the number of atoms; the chemical compound n-hexane has the structural formula CH3CH2CH2CH2CH2CH3, which shows that it has 6 carbon atoms arranged in a chain, 14 hydrogen atoms. Hexane's molecular formula is C6H14, its empirical formula is C3H7, showing a C:H ratio of 3:7. A chemical analysis of a sample of methyl acetate provides the following elemental data: 48.64% carbon, 8.16% hydrogen, 43.20% oxygen. For the purposes of determining empirical formulas assume. If this is the case, the percentages will be equal to the mass of each element in grams. Step 1: Change each percentage to an expression of the mass of each element in grams; that is, 48.64% C becomes 48.64 g C, 8.16% H becomes 8.16 g H, 43.20% O becomes 43.20 g O.

Step 2: Convert the amount of each element in grams to its amount in moles = 4.049 mol = 8.095 mol = 2.7 mol Step 3: Divide each of the resulting values by the smallest of these values 4.049 mol 2.7 mol = 1.5 8.095 mol 2.7 mol = 3 2.7 mol 2.7 mol = 1 Step 4: If necessary, multiply these numbers by integers in order to get whole numbers. 1.5 × 2 = 3 3 × 2 = 6 1 × 2 = 2 Thus, the empirical formula of methyl acetate is C3H6O2. This formula happens to be methyl acetate's molecular formula

Good Souls

"Good Souls" is the second single from the album Love Is Here by British alternative rock band Starsailor, released in 2001. It is the first Starsailor song to have a promotional video; the video starts with James playing the guitar alone sitting on a chair by the time the camera shows the band member Barry throwing accidentally a bottle of water after he drank and the water starts to spill over the floor while James Walsh walks in order to meet the band there's else a scene that shows how Ben Byrne throws a broken drumstick and how it falls. Some of the captures shows directly James's face specially the final scene when the camera focus on James face for a second and the lights turn off. In another scene James ` Stel' Stelfox dets closer to the transistors; this is Starsailor's first video filmed black and white and else the first introspective video of their career.

Erechtheis

Erechtheis was a phyle of ancient Athens with fourteen demes. The phyle was created in the reforms of Kleisthenes. Although there is little specific reference to the tribe, an inscription dated to either 460 or 459BC in the form of a casualty list allows a little access. Two generals are listed for the single year on which the text insists, Phchos is followed in the list by Hippodamas indicating that he succeeded the former in the summer due to the death of Phchos. Alternatively they were elected together, not uncommon later; the presence of a seer on the list is surprising, as their role of accompanying the army to interpret omens through the analysis of the entrails of sacrificed animals does not seem dangerous. That there is no other tribe mentioned on the inscription is unusual as most casualty lists arrange the dead according to tribe on a single Stele or group of joined stelai; this stele, appears by the smoothness of the un-inscribed faces of the stone to have been solitary. Despite the use of personal names on the list, the repetitions means that the absence of patronymics prevent the identification of the individual and family referred to in each case.

This deprivation of social status could be an example of democratic intentions, but it does something to lessen the personal impact of the list through an attempt to prevent social discord which would have resulted from the realisation of the impact on individual families and communities. Had the inscription been divided into the fourteen demes, the exact effect of the losses on individual villages would have been much clearer. Despite the removal of the obvious social status of family associations, names themselves can be used to infer certain things. Greek naming patterns mean that repeated names could indicate family links, although more social study of Greek names is needed to understand this it is that certain names could imply wealth or foreign connections. Examples of this are the names Arcesilas in line 154 of the casualty list, a name common in Sparta at the time, but only in Athens; the demes were Agryle, Themakos, Kedoi, Pambotadai, Pergase, Sybridai. Critias is thought, hypothetically.

Ch√Ęteau de Levesville

Château de Levéville or or Levesville, one of the Châteaux of the Loire Valley, is situated in Bailleau-l'Évêque on the outskirts of Chartres in the Eure-et-Loir department. The castle was built in the 15th century and remodelled in the 17th and centuries; the château stands on a plateau above the city of Chartres. The first owners, whose name was Levéville, were mentioned at the end of 11th century in the chartulary of the abbeys of Saint-Père Abbey in Chartres and Notre-Dame de Josaphat in Lèves; as vassals of the Bishops of Chartres, the lords of Leveville were passionate defenders of the early Dukes of Chartres. For more than two centuries, the knights of Leveville were present in the history of Chartres and its region. According to several drawings from the Gaignières collection, the first local noblemen wore suits of armour, it was Michel le Vacher who, between 1479 and 1506, ordered a new castle to be built with the main residential structure encircled by a moat. The courtyard was enclosed by walls, towers with artillery pieces stood on each side.

A second wall protected the courtyard and moats. There were several towers and the wall was encircled by the moat. In April 1656, all the land of Levéville and its surroundings was given the status of a district. In July 1610, François III Briçonnet, the reign counselor and administrator of the Paris Chamber of Accounts, became the new owner of the castle. After his wedding with Anne des Landes, the Lady of Magneville, he issued an order for the castle to be reconstructed in the style of Louis XIII; the result was a multicolored brick facade for the right wing. Window dormers and a belfry with a dome on pillars were erected. Two of four towers and a drawbridge were demolished at that time; these two towers were modified into a pavilion with small loopholes. The couple built the Mary Magdalene Chapel not far from the castle, because Bailleau Church was two miles away. In 1813, the castle with all the furniture was sold to Nicolas François Barthélémy, former inspector of this area, residing in Paris.

After his death the castle was passed to his sons: August. According to local traditions, the Barthélémy brothers were told to be close friends of Alexandre Dumas, who made several visits to Levéville, it was rumored he was in love with née Pauline de Baltus. Both the Barthélémy brothers resided in Levéville castle, undertaking many improvements between 1860 and 1880. Large slate roofing was replaced by a lighter design. Three central windows on the ground floor provide a view of the facade from the side of the courtyard. Two small oval windows were replaced by three windows in stone. Small apertures were made in the towers; the antechamber was ornate panels decorated the area in front of each door. The château was plundered during the Second World War. During the Nazi occupation, the Germans used it as a control center until it was taken by US troops in 1944. After the war, the castle and all its utility structures were leased to the Ministry of Justice from 1946 to 1956; the new garden was altered in 1971 and it was enlarged by the well-preserved remains of the old garden.

Behind the château a lot of hornbeam and shrubbery was planted. A new pond with hornbeam plants was added. In 1976, Château de Levéville was inscribed on the list of monuments historiques by the French Ministry of Culture. In 2005, the château was sold to Alexey Semin, the chairman of the board of directors of the ASG Investment group of companies. On the website of the International Antique Institute of ASG it is possible to make a 3D-tour throughout the castle Cercle de recherches genealogiques du Perche-Goiet GeneaWiki. 28022 - Bailleau-l'Évêque le blog francois.

J. J. Haverty

James Joseph "J. J." Haverty was the founder of Haverty Furniture Co. headquartered in Atlanta, Georgia. Haverty was born in Atlanta to the Irish immigrants Thomas and Margaret Cannon Haverty. Haverty was a devout Catholic, named a Knight of St. Gregory by Pope Pius XI and helped found the Cathedral of Christ the King in Atlanta, he began his first job, as a clerk for local dry goods merchant John Ryan. He took Havertys public just before the stock market crash of 1929. In 1885, he started an emporium in downtown Atlanta with Charles. In 1889, he partnered with Amos G. Rhodes to start a law firm, which became known as Rhodes, Snook & Haverty after P. H. Snook joined it in 1894. In 1908, the Rhodes-Haverty partnership was dissolved, at which point Haverty founded the Havertys furniture company, along with his son and other business associates, he has been called the first "important collector of works of art" in Atlanta, with an eye for American Impressionist and Realist paintings, including work by Childe Hassam, Maria Turner, Albert P. Ryder, Jonas Lie and Henry O. Tanner.

During the 1920s, he was a major supporter of New York's Grand Central Art Galleries, he organized a series of successful exhibitions of American art at the Atlanta Biltmore Hotel. These events lead to the creation of Atlanta's High Museum of Art. Many Haverty collection paintings were donated posthumously to the High and remain in the museum's permanent collection. Haverty is buried, along with other family members, in Atlanta's Westview Cemetery. Results for JJ Haverty at the Frick Collection
