TLC was used to identify the actual unknown product as well as other products/reactants present in the filtered solution. The procedure was conducted by placing a TLC plate in a developing chamber that is filled with a small amount of solvent. The solvent cannot be too polar because it will cause spotted compounds on the TLC plate to rise up too fast, while a very non-polar solvent will not allow the spots to move. The polarity of the spots also determines how far it moves on the plate; non-polar spots are higher than polar ones. After spots on the TLC form, the Rf values are calculated and used to analyze the similarity of the compounds.
Ivy Mike, the first thermonuclear bomb, evaluated in 1952 on the Marshall islands was equivalent to 22,928,077,120 pounds of explosive trinitrotoluene (TNT) (1). The hydrogen bomb is said to be 1,000 times more powerful than the atomic bomb (1). ‘Ivy King was the largest atomic bomb exploded by the United States, dropped from a bomber plane at Runit Island in the Enewetak Atoll, on November 16, 1952, resulting in a 1,000,000,000 pound blast (2). However, when the hydrogen bombs, nicknamed the ‘Tsar Bomba’ was dropped by Russia at a bay in the Arctic Circle on October 30, 1961, it was declared the most powerful nuclear weapon ever detonated, at 110,231,131,092.5 pounds of explosive trinitrotoluene or TNT
He is mostly known for his mass–energy equivalence formula E = mc2, which has been recognized as "the world 's most famous equation". ii. Can you give me an example of one of his contributions do science? 1. In the year of 1905, Albert Einstein published a paper advancing the hypothesis that light energy is carried in discrete quantized packets to explain experimental data from the photoelectric effect.
ASBESTOSIS Overview Asbestosis is a chronic (long-term) lung disease that develops from inhaling asbestos fibers resulting in the scarring of lung tissues and shortness of breath. Other names for this disease are interstitial pneumonitis and pulmonary fibrosis. Asbestos is a group of minerals with thin microscopic fibers that 's resistant to heat and corrosion. This disease usually goes undiagnosed for many years after the exposure happened. Causes Asbestosis is associated with chrysotile fiber.
pH levels are 7.35 to 7.45. Respiratory Alkalosis: A interference that is in acid and base balance that is cause by alveolar hyperventilation. When being diagnosis with respiratory alkalosis the reason could be a nonlife threatening disorder. Normal levels are pH>7.45 and HCO3. There are different things that can cause respiratory
The temperature of grey water is slightly high (usually lies between 18-38 degree Celsius) due to use of warm water for bathing (Eriksson et al., 2002). Turbidity of grey water may vary from 5.6 NTU -33.6 NTU for low strength and can be about 67.4 NTU for high strength waste water. Total solids in grey water in one study was found to be averaged at 29 mgL-1 for low strength and 93 mgL-1 for high strength grey water, where the low strength waste water “contains 10% (v/v) mixture of Tesco Value shampoo in tap water” (Winward et al., 2008).
This helped prove his theory of the proton’s existence because when the alpha radiation occurred it turned the old element into a new element by removing two protons. Lastly the article also mentions that, “In 1898, Ernest Rutherford began studying the radiation emitted by uranium. His experiments led him to conclude that radioactivity must have at least two components; and he named them alpha and beta rays after the first two letters of the Greek alphabet.” The research he conducted lead him to realized that beta rays were way more penetrating than alpha
What were the causes of the atomic bombings on Hiroshima and Nagasaki and their effects on Japan’s economy? By: Ronan Uy ABSTRACT Warfare has been through many periods of technology, in spite of this a single aspect remains constant: death. Though there were numerous deadly weapons utilized in war, the deadliest of them all is the atomic bomb. The atomic bomb, is as defined by britannica.com “a deadly weapon caused by the sudden release of energy after the splitting, or fission, of the nuclei of heavy elements like uranium.” In 1945, the United States (US) dropped two atomic bombs, one in Hiroshima and the other in Nagasaki ending WWII. It was the first event in which the whole world witnessed the power of nuclear weapons and the only time nuclear weapons have been used in war.
John Townsend and Robert Millikan later on were able to determine their exact charge and mass. In 1911 Rutherford and German physicist Hans Geiger found out that electrons orbit the nucleus of an atom. Radiation is emitted during movement from one orbital to another. In 1945 Glenn Seaborg identified lanthanides and actinides , which are usually placed below the periodic table. Till this day, scientist are still trying to enhance their knowledge on the Periodic Table and its
In the alkali-catalyzed process, the presence of free fatty acid (greater than 1 mg/g KOH) and water in the oil can cause high amounts of undesirable soap formation, also consuming some quantity of alkaline catalyst and reduces the eﬀectiveness, all of which result in a lower conversion. Therefore, for the feedstock with high free fatty acids, it is essential to have a pretreatment stage before subjecting it to transesteriﬁcation process.  1.2 Pretreatment Process for Waste Cooking Oil Pretreatment of waste cooking oil consists of physical treatment for removing the suspended solid contaminants and chemical treatment processes mainly for deacidiﬁcation. A ﬂow sheet giving the diﬀerent approaches for pretreatment of waste cooking oil is shown in Figure 2. Issariyakul et al.
The exposure from the Trinity Bomb test was over 10,000 times more than the recommended dose of radiation that people should be exposed to. Next I’ll tell you about Fat Man. In the implosion type bomb there is a core of plutonium that is wrapped with thousands of pounds of explosives. Fat Man was dropped on Nagasaki on August 9, 1945. It was the second bomb we dropped during the war.
The National Mining Association reported that in 2009, 55.4 percent of Maryland’s electricity came from it. It is the dirtiest fossil fuel by nature and when it is burned, it emits greenhouse gas carbon dioxide and other air pollutant which creates smog. The Union of Concerned Scientist said that “Burning coal is also a leading cause of smog, acid rain, and toxic air pollution.” According to the US Energy Information administration, in 2013, Maryland 's Port of Baltimore was the second in the nation to export coal. Maryland energy consumption on coal was estimated at 183.2 trillion
Electronic cigarettes can effect your ability to cough and make it harder. Even if it is a time when it is needed to get out mucus and other bad things, you wont be able to get it out. “It would be similar to smoking, only less…and you might get a chronic cough, or raise a little [mucus].”-Dr. Norman Edelman Also if you have a device that gets to high temperature and you are using a device with nickel or titanium coils it can release toxic chemicals. Vaping can also cause a chronic cough or pneumonia, since there is water vapor being inhaled depending on how much you use your device. The vapor devices themselves are not very harmful at all, the nicotine is the worst part, that’s because nicotine is an addictive drug and can cause heart problems.
Mosquitos carry several diseases. Another statement the article made is “ The state and federal gov. has said the water treated with this chemical is safe.” But that is not true if you can still get asthma, eczema, and etc. The only difference is it takes longer. Chlorine will dissolve when it’s boiled in the water.
