6. Zinc Sheet: a rectangular, thin, sheet like metal, gray/silver. 6 5 4 3 2 1 * Solubility of solid iodine; 1. Solid iodine in 1 mL of water is slightly soluble, because the solution turns into a light brown/yellow color. However majority of the solid Iodine was left at the bottom of the test tube; which leads to the conclusion that it’s not reactive on water.
These industrial activities have raised atmospheric gases such as carbon dioxide which contribute to greenhouse gases. The extra amount of these gases mean there is a thicker layer, meaning the gases absorb outgoing long-wave radiation which traps in too much heat. Increasing amounts of CO₂, methane, nitrous oxide, water vapour and ozone all contribute to this. The main cause in this rise is the burning of fossil fuels such as coal, oil, natural gas and petrol. Since the industrial revolution the levels of atmospheric CO₂ have increased from 280 parts per million to 380ppm for the past 10,000.
This is because when an azeotrope is boiled, the resulting vapour has the same ratio of constituents as the original mixture of liquids. Each azeotrope has a characteristic boiling point. The boiling point of an azeotrope is either less than the boiling points of any of its constituents (a positive azeotrope), or greater than the boiling point of any of its constituents (a negative azeotrope). The azeotropes of cyclohexanol/water and cyclohexene/water are both positive azeotropes. The separation of cyclohexene could not depend on distillation alone.
In the experiment, toluene was alkylated with 2-chloropropane to synthesize isomers of isopropyltoluene in 47% yield, weighing 2.66g. The final product had a purity of 91.8% while the appearance was a colourless clear liquid with a strong odour. The results suggest that although the product yield was low, the experimental design led to the production of isopropyltoluene in high purity. REFERENCES 1. Smith R, McKee J, Zanger M.

Acetone is one of the most widely used industrial solvents and is increasingly used as a chemical intermediate. Acetone is low in toxicity. It occurs naturally in plants and our body’s metabolism. It is also present in vehicle exhaust, tobacco smoke, and landfills. Acetone does not cause adverse health or environmental effects at levels typically found in the workplace or environment.
This single metabolic fact accounts for the profound changes in not only respiration, but also in cardiac and circulatory physiology during exercise. Increased oxygen supply is provided by increases in both arterial oxygen delivery and tissue oxygen extraction; at the same time there is increased carbon dioxide transport on the venous side. The need for increased gas exchange by exercising muscles leads to the following general physiologic
It showed that 2011 figure was increased by 7.3%. Coco-Cola is one of the largest and well-known beverage company all-over the world as Coca-Cola sells beverages to more than 200 countries. Coco-Cola could make a long-term investment at the current price, the valuation given the ratios to be margin in a safe way. Revenue Growth: 8.5%. Cash flow Growth: 8%.
However, the alcohol remains fairly constant in the form of glycerol or in other words propane -1,2,3- triol. This form of alcohol contains a hydroxyl allowing longer chains to form of carbon. 7. A common commercial use for esters is in the perfume industry where a synthetic scent is created within labs through the process of esterfication. For example, Benzyl Acetate is one form of an ester that can be used as to create a perfume
(Champagne & Harpham, 21) Texas seems to be urbanizing more and more. This shift brings about economic growth and diversification which means new roads will have to be built, more construction, and expanded water and sewer systems (window.tx.state.us, Susan Combs, Texas in Focus: A Statewide View of Opportunities) thus creating many more jobs as well. A state that was once majority Anglo’s has become a state of all races, which has also driven the growth in population. Texas is now a state where different ethnicities have a larger number that the Anglo’s. People are coming from all over to work in the oil field particularly.
“It’s an industry that runs to nearly $3 billion a year in the U.S. alone ... It’s a real growth industry, expanding in the US at 10% or more yearly.” (3) With profits like these, no wonder the drug companies want a cut. Last year the United States paid Turkey $35,000,000 to suppress its opium crop. In effect, our government was erecting a protective tariff against foreign heroin, thereby subsidizing the domestic methadone market, dominated by such corporate giants as Eli Lilly and Malinckrodt Chemical. Methadone is a synthetic addictive narcotic, three to four times stronger then heroin. Every day 10.9 people die from Methadone (according to 2004 stats, not including car accident deaths caused by drivers under the influence
