LETS UNDERSTAND CHEMICAL

Alleged chemical attack in Syria, Aug. 21, 2013

Clear topic

The United Nations is investigating a sarin gas attack in Syria. The Syrian government denied reports its troops used chemical weapons on Aug. 21, 2013, dismissing the claims as baseless.

The U.S. estimates that the attack killed more than 1,400 people, including 426 children. Other estimates are somewhat lower. -

PEOPLE LET UNDERSTAND THE WORD CHEMICAL!!!!

In chemistry, a chemical substance is a form of matterthat has constant chemical composition and characteristic properties.^[1] It cannot be separated into components by physical separation methods, i.e. without breaking chemical bonds. It can be solid, liquid, gas, or plasma.

Chemical substances are often called 'pure' to set them apart from mixtures. A common example of a chemical substance is pure water; it has the same properties and the same ratio of hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Other chemical substances commonly encountered in pure form are diamond (carbon), gold, table salt (sodium chloride) and refined sugar (sucrose). However, simple or seemingly pure substances found in nature can in fact be mixtures of chemical substances. For example, tap water may contain small amounts of dissolved sodium chloride and compounds containing iron, calcium and many other chemical substances.

Chemical substances exist as solids, liquids, gases, or plasma and may change between these phases of matter with changes in temperature or pressure. Chemical reactions convert one chemical substance into another.

Forms of energy, such as light and heat, are not considered to be matter, and thus they are not "substances" in this regard.

10 of the Most Dangerous Chemicals in the World

SEXPAND

10. Digoxin

A purified extract of the foxglove plant. In proper quantities, digoxin increases the efficiency of the heart. Charles Cullen, a nurse and the "angel of death", used pharmaceutical grade digoxin to kill over forty patients using the drug.

9. Hydrogen peroxide

The hydrogen peroxide in your bathroom cabinet has a concentration of 3 to 6%. At higher concentrations, it's a rocket propellant. Hydrogen peroxide is extremely volatile, with the merest nudge setting off an explosion in laboratory grade solutions (>70% hydrogen peroxide). The 2005 London subway bombers used concentrated hydrogen peroxide as an explosive in the attacks that killed 52 people.

8. Ethylene glycol

It's in your car as antifreeze. It's cheap. It looks so damn simple. It has a moderate toxicity level, however, the sweet taste can make one easily surpass that boundary, leading the ethylene glycol to be metabolized into the more dangerous oxalic acid. Keep it away from animals and pets, as they are likely to lap up the liquid as a food source. If you do ingest a large amount of ethylene glycol, death is slow, knocking out organ systems systematically over the course of 72 hours. The treatment is administration of grain ethanol, as the ethanol competes with ethylene glycol for binding in your body.

7. Nicotine

A member of the nightshade family of plants, this oily liquid that makes up between 0.6 to 3% of a cigarette's mass. Contact with the liquid pure form can cause death within hours, as nicotine passes through the dermis and heads directly for the bloodstream. Overdoses and death can easily occur in those smoking cigarettes with nicotine patches applied on their body.

6. Sodium cyanide

A routine industrial reactant, but one false step results in the smell of almonds, then death within seconds. Cyanide binds to cytochrome c oxidase, a protein in the mitochondria, and stops the cells from using oxygen.

5. Strychnine

Commonly used as a pesticide to kill large unwanted pests like rodents and birds. Due to the ease of concealment, strychnine is rumored to have killed many historic figures includingAlexander the Great and Blues musician Robert Johnson.

4. Tabun

One of the first nerve agents discovered, this liquid is known for a fruity odor and can be sprayed as a mist that causes convulsions and paralysis. Tabun itself is not extremely deadly, but the success of this chemical compound in war led to the development of deadlier toxins like ricin and soman. Iraqi soldiers used Tabun in the final days of the Iran/Iraq war to kill thousands of Iranians.

3. 2,3,7,8-Tetrachlorodibenzo-p-dioxin

Heard of Agent Orange? 2,3,7,8-Tetrachlorodibenzo-p-dioxin was thecontaminant in Agent Orange. That's a bastard chemical. Agent Orange was created to cause defoliation of dense areas in Vietnam, but this contaminant led to severe prenatal deformities and skin lesions.

2. VX

One of the first chemical WMDs, researchers initially produced VX for retail sale in the 1950s as a pesticide. Thankfully, your likelihood of coming in contact with VX is extremely low - the world's stockpiles have been destroyed, including the United States' main stockpile in Anniston, AL.

1. Batrachotoxin

The most potent non-peptide based poison known. Batrachotoxin gained fame though its use in poison darts made from frog excretions. The frogs themselves don't produce the toxin directly, but through digestion ofMelyrid beetles the frogs eat.
