renewable energy which means that it can be used as long as humans can and it has little pollution. People should try their best to expand the use of solar energy and to relieve the energy problems. If they use fossil fuels‚ fossil fuels will release carbon dioxide and some other polluting gas and humans cannot use them forever due to the limited resources. People should promote solar consumption with joint efforts instead of non-renewable

experiment #1 is not just an ordinary rock because it’s a calcium carbide and was known here in the Philippines as kalburo. When this chemical compound is mixed with water there will be a chemical reaction and it produces acetylene gas. The two anions of carbon‚ the carbide (C4-) and dicarbide (C22-) ions react with water to produce hydrocarbons. The carbide ion gives methane gas‚ and the dicarbide ion gives acetylene gas. This video shows the reaction between calcium carbide and water to produce acetylene

reaction will change the toluene to benzanoic acid and the color of potassium manganate change from purple to slight purple Objective To compare the reaction of aliphatic and aromatic hydrocarbon. Aliphatic compounds are hydrocarbon chains - strings of carbon atoms connected to each other with hydrogen atoms hanging off the sides of the chain.Aromatic compounds are rings - so take the chain and connect the two ends together to form a continuous loop.aliphatic compound are easier to react than aromatic

Boron is used in pyrotechnics and flares to produce a green color. Boron has also been used in some rockets as an ignition source. Boron is used to control nuclear reactions. It is an excellent neutron absorber. Alloyed with steel or reacted with carbon‚ titanium or zirconium‚ it is used in control rods for nuclear reactors Boron is an essential nutrient for all green plants Bibliography: http://chemtopics.com/elements.htm http://www.webelements.com/boron/

When the polymer is exposed to microorganisms found in soil‚ sewage‚ river bottoms or other similar environments‚ the decomposition into carbon dioxide and water may occur. Other properties of Biopol include its insolubility in water‚ good oxygen permeability‚ ultra violet resistance but poor resistance to acid and bases‚ solubility in chloroform and other chlorinated hydrocarbons‚ biocompatibility

amounts of alcohol will kill someone. According to Dr. Lester Grinspoon author of Marijuana: The Forbidden Medicine‚ “The only well confirmed negative effect of marijuana is caused by smoke‚ which contains three times more tars and five times more carbon monoxide than tobacco. But even the heaviest marijuana also relieves nausea suffered by cancer patients undergoing powerful chemotherapy. It is also used by patients who have multiple sclerosis and AIDS. Marijuana is also proved to be effective in

Try Synthetic Ivory In a time of limited resources‚ and with the population of the human race increasing at an alarming rate‚ demand for products will be at an all time high. This is why synthetic resources will become of great importance in the near future. For instance‚ ivory is high in price and involves the hunting of an endangered species‚ the elephant‚ this is why creating a synthetic form of this material would not only make it more affordable‚ it would also help preserve wildlife. A synthetic

unknown compound was 121. Since the molecular weight is an odd number‚ Nitrogen is present in the compound. By dividing the molecular weight by 13‚ we get 9 and remainder of 4. The maximum Carbons the compound had are 9 and 13 Hydrogens. Since Nitrogen was present‚ I had to add it to my formula and subtract a Carbon and two Hydrogens from the base formula. Hence the final molecular formula would be C8H11N with a HDI of 4. Looking at the IR spectroscopy‚ there is a sharp peak at around 3000 cm-1‚ which
