Tetrachloroethylene is a clear, nonflammable liquid, and is a commonly used solvent that has been in commercial use since the early 1900s. It can be found in water repellant, paint remover, printing ink, glue, sealant, polish, and can also be used to make other chemicals.
The objective of the Unknown White Compound experiment was to investigate the compound’s physical and chemical properties to correctly identify and then synthesize the compound. The first step was to test the compounds solubility and create a solution with distilled water. Next, a pH test was conducted by testing the unknown compound using pH paper. Following, the flame test was used to determine the cation and the ion test was used to determine the anion, which concluded the compound to mostly be potassium nitrate. Next, a conductivity probe and pH probe were used to confirm the unknown compound to be potassium nitrate. The final step was to synthesize potassium nitrate using silver nitrate and potassium chloride. The experiments listed above concluded the unknown white compound to be potassium nitrate.
Although this application has been discontinued, Chloroform is greatest known for it’s first use as an anesthetic. Prior to Chloroform, ether was the prevailing anesthetic for surgical procedures.However once Chloroform was introduced, ether was quickly replaced. Unlike ether, chloroform’s characteristically sweet odour isn 't irritating and was highly adored because it is 40 times sweeter than sugar. The sweetness of Chloroform coupled with it’s anesthetic properties made it a popular ingredient for toothpaste, cough syrup and skin ointments. Although nitrous oxide is the currently prevalent anesthetic used today, Chloroform is more effective as an anaesthetic. Chloroform’s rapid effects and great potency is due to it’s property of being well absorbed, metabolized, and eliminated rapidly by the body after oral, inhalation, or dermal exposure.
A mole is a unit of measurement that follows the rule of ; 1.00 mole = molar mass = 6.02 x 10^23 atoms/ ions/ molecules / formula units = 22.4 L of any gas at standard temperature and pressure. That formula was used to determine the mass of the anhydrated substance. A anhydrate is a substance with water heated out of it. The purpose of this lab was to determine how many moles of water are
Types of services the company will provide: Floral warehouse- import and sell flowers in bulk. This will be warehouse operating under Evergreen Petals to supply bulk purchases of flowers. It will also be a storage warehouse for ChloroFloral.
NaCl is sodium chloride,and SCl_2 is a compound known as sulfur dichloride. The compound NaCl or sodium chloride is or would be classified as an ionic bond. Then the compound known as SCl_2 or Sodium dichloride would be classified as yet again another Ionic bond. The two types of covalent bonds are regular covalent bonds which the elements atom is partially full but not all the way to the point were you can share electrons. Carbon forms covalent bonds.
Molar Mass Molar mass is the mass of 6.022 x 1023 atoms. M of compounds is the sum of the elements that the compound is made up of. Freezing-Point Depression Freezing-point depression is when you add a solute to a solvent, which decreases the freezing-point of said solvent. This process is used for melting ice, and keeping liquids from freezing in the winter.
According to the National Science Board’s science and engineering indicator, in 2006, it show that the world high technology manufacturing output is came out from America, it was around 40%
Introduction Chevron Phillips Chemical Company is the major producer of Cyclohexane. This successful company hoses the three largest cyclohexane plants in the world. Many are puzzled by how the production of cyclohexane seems to have become stagnant. Perhaps this is due to the cost of benzene increasing or the demand increasing. Through thorough investigation, the answer to this question and many more can be answered.
Properties of Substances Express Lab 1)The purpose of this lab was to compare the physical properties of different types of solids and how the properties of solids are determined by their intermolecular forces and their intramolecular bonds. Then we were to classify each type of solid as either ionic, metallic, non-polar molecular, polar molecular, or network. Paraffin wax classified as a non-polar molecular, Silicon dioxide was classifies as a network, Sodium chloride was classified as ionic, Sucrose was classified as polar molecular and Tin was classified as metallic. (2)The intermolecular forces that are present in Paraffin wax are dispersion forces, because it is non-polar and carries a negative charge. Followed by Sucrose that has
When elements form compounds, they create a new substance.For example, when two hydrogen molecules (H) and one oxygen molecule (O) combine they create water (H_2O) or when sodium (Na) and chlorine (Cl) form a compound they create Sodium Chloride (NaCl) or more commonly known as table salt.But we must ask how do these compounds stay together without splitting apart.The answer is a chemical bond.A chemical bond is an attraction between atoms by sharing electrons. There are three types of chemical bonds: Ionic, Covalent, and Polar covalent. Elements with low electro negativity usually form Ionic bonds, such as salt (NaCl) and usually one element gives up an entire shell to give to the other element. Elements with similar negativity form Covalent

massive quantities of ethyne are employed in metal cutting. Its small scale use of is within the preparation of vinyl ethers from alcohols along with phenols using Na-or K-hydroxide as catalyst in liquid phase. Large amount of alcohols will be vinylated however solely few has business
INTRODUCTION Carbon tetrachloride (CCl4) - an organic industrial solvent used in industry – is a vigorous carcinogenic agent that may create dysfunction of lung, liver, kidney and nervous system (1, 2). After being absorbed from gastrointestinal system, respiratory system and skin CCl4 is metabolized by cytochrome P-450 and exerts its toxic effects via its metabolites trichloromethyl free radical and trichloromethyl peroxyl radical (1-3). These free radicals interacts with fatty acids of lung cell membrane and increase lipid peroxidation and DNA fragmentation. Moreover, they suppress antioxidant enzymes including catalase, superoxide dismutase, glutathione (GSH), oxidized glutathione (GSSG), glutathione reductase and glutathione peroxide (1,2,4).
The chlorine atoms that are replaced by hydrogen atoms causes a higher presence and both are covalent bondings with strong intermolecular forces. The double bondings (Or triple bondings) in hydrocarbon tends to be stronger, but the chemical is flammable. Fluorocarbons are not flammable and are also polar covalent bondings, making them stable to ultraviolet radiation and prevents them from catalysing ozone depletion. Hydrochlorofluorocarbons (HCFCs), one of the alternatives that contains C-Cl bondings have most of its molecules dismantled in the lower atmosphere before reaching the stratospheric ozone layer. Another chemical, Hydrofluorocarbons (HFCs), having no chlorine atoms which does not bring harm to the ozone layer is considered the best alternative since they are not flammable, such as CF3CH2F,1,1,12 tetrafluoroethane.
