Sodium Bicarbonate Sulfuric Acid
865 wordsNitroglycerin (C 3 H 5 N 3 O 9) Nitroglycerin is one of the most sensitive explosives ever to be commercially produced. It is a very dense liquid, and is sensitive to heat, impact, and many organic materials. Although it is not water soluble, it will dissolve in 4 parts of pure ethyl alcohol. Heat of Combustion: 1580 cal / g Products of Explosion: Carbon Dioxide, Water, Nitrogen, Oxygen Human Toxicity: Highly toxic vasodilator, avoid skin contact! Although it is possible to make it safely, it is...

Effects Of Acid Rain Sulfur Dioxide And Nitrogen
3,730 wordsWhat is acid rain? Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture. The term 'acid rain' is slightly misleading, and would be more accurate if deemed 'enhanced acid rain', as rain occurs acidic naturally. Acidity is measured on what is know as the pH scale. Fourteen is the most basic, seven is the most neutral, and zero is the most acidic. Pure rain has a pH level of 7, which is exactly neutral. The acidity of rain is determined by t...

Copper In Nitric Acid
554 words3 Cu + 8 HNO 3 -- 3 Cu (NO 3) 2 + 2 NO + 4 H 2 O The balanced equation seen on the top is what you attain when you place copper metal in concentrated nitric acid. In this process the identifiable characteristics of the metal will be completely changed and a new substance, cupric nitrate, will be formed. Copper forms two series of chemical compounds: cuprous, and cupric. Cuprous compounds are easily oxidized to cupric, in many cases by simple exposure to air; cupric compounds are stable. When nit...

Td Tr Tr Td Erectile Dysfunction
1,318 words... The physiologic mechanism of erection of the penis involves release of nitric oxide (NO) in the corpus cavernous during sexual stimulation. NO then activates the enzyme guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate (cGMP), producing smooth muscle relaxation in the corpus cavernous and allowing inflow of blood. Sildenafil has no direct relaxant effect on isolated human corpus cavernous, but enhances the effect of nitric oxide (NO) by inhibiting phospho...

Chlorofluorocarbons Cfcs Ozone Depleting
1,295 wordsThe ozone layer is one of the oldest things on the planet, older than any of the ancient creatures we see in our museums today. The ozone layer has provided protection for the living components under it for millions of years, and without the ozone layer, we most likely would not be here today. Our evolution would have been cut off millions of years ago without our planets ability to provide protection from the ever-harmful rays from our sun. Each year since the late 1970 s much of the protective...

Ph Of 5 Sulphur Dioxide
1,087 wordsAcidity is measured using a pH scale, with the number 7 being neutral. A substance with a pH value of less than 7 is acidic, while one of a value greater than 7 is basic. A substance with a pH of 6 is 10 times more acidic than another with a pH of 7. Usually the pH of 5. 6 has been used as the baseline in identifying acid rain, although there has been much debate over the acceptance of this value. Interestingly enough, a pH of 5. 6 is the pH value of carbon dioxide in equilibrium with distilled ...

Clean Air Act H 2 O
1,801 wordsAcid rain is exactly what it suggests- rain that is acidic. The definition of 'acid rain' is rain with a pH of below 5. 6. Rain becomes acidic because of gases that dissolve in the rain. Approximately 70 % of acid rain is a result of dissolved sulfur dioxide (SO 2) which forms Sulfuric Acid. The remaining 30 % or so comes from various Nitrogen Oxides (mostly NO 2 and NO 3 which has collectedly adopted the mane Nox). There is also a small percentage of hydrochloric acid that makes up hydrochloric...

Hydrogen Cyanide Chemical Weapon
605 wordsSo, what were the evidences, which supported the statement of the Judge Duffy, that there had been cyanide in the WTC bomb? The main question to be solved here lied in the following: what could be the consequences of mixing cyanide with nitric or sulfuric acids, both of which had been found in the bomb fragments? The FBI chemist Steven Burgmeister was the main person to be inquired about the results of the forensic chemical analysis. The thing is, that Burgmeister never made it clear, that he ha...

World Trade Center U S Senate
1,551 wordsThe World Trade Center bombing in February, 1993, became a landmark in the new wave of terrorism, with civilians involved into the tragedy. The World Trade Center served as the target of the bombing. As a result of the terrorist act, six people were killed and more than thousand were injured. But taking into account the fact, that there used to be about 20, 000 people usually working at the Center simultaneously, and more than 80, 000 people visited or traveled along the complex, the consequence...

Nitric Acid Scientific American
825 wordsChemistry Connections of nitrogen - saltpeter, nitric acid, ammonia - were known long before invention of nitrogen in a free condition. In 1772 D. Rutherford, burning phosphorus and other substances in a glass bell, has shown that the gas remaining after combustion does not support breath and burning. He named it suffocating air. In 1787 A. Lavoisier has established, that the "vital" and "suffocating" gases included in air, are simple substances, and has offered the name "nitrogen." In 1784 G. C...
