Reply
A chemical weapon is a device that uses chemically formulated substances to inflict death or harm to humanbeings. They are classified as weapons of mass destruction, and have been “condemned by the civilized world”. They have been used in past conflicts and it is anticipated that their potential for future use is always possible. Numerous international agreements are in force with regard to chemical weapons.VX

Schrader worked for IG Farben, a company that later used slave labour from the Birkenau concentration camp to produce its products. Another one of Fraben’s invention was Zyklon-B, a type of hydrogen cyanide used by the Nazis to gas victims in those same camps during World War II. Tabun is also an organophosphate like many pesticides and is among the easiest to nerve gases to manufacture. |

Sarin
| Sarin |
 It is a colourless odourless nerve gas. It belongs to organophosphate chemical group. Most of the moderninsecticides too belong to this family of chemicals. |
| US, Russia and Iraq had produced Sarin. By the end of World War I, most European powers had integrated gas warfare capabilities into their armies at some level, and nerve gases such as sarin, small amounts of which cause paralysis or death, were developed in Germany between the two world wars. Despite the availability of gases, only Japan used them in China—as World War II became global. After World War II, knowledge of nerve-gas manufacture became widespread. |

Condoms
| Condoms |
| Condoms are a commonly used contraceptive device. It is a sheath or covering which fits over a man’s penis, and which is closed at one end. Mostly it is the male condom that is used. A type of female condom is also available. It is a female condom, or vaginal sheath, which is used by a woman and fits inside the vagina.Use of Condoms is very important in the prevention of Sexually Transmitted Diseases. |
| Male condom is made of latex or polyurethane. Latex condoms are more reliable. Most of the condoms are lubricated. Some condoms are not lubricated at all, some are lubricated with a silicone substance, and some condoms have a water-based lubricant. The lubrication on condoms aims to make the condom easier to put on and more comfortable to use. It can also help prevent condom breakage. Some condoms and lubricants contain spermicide. |
  |
| When using only put on a condom once there is a partial or full erection. If the penis is not circumcised, pull back the foreskin before rolling on the condom. You need to use a new condom every time you have sexual intercourse. Never use the same condom twice. When you have ejaculated or finished having sex, withdraw the penis before it softens. Make sure you hold the condom against the base of the penis while you withdraw, so that the semen doesn’t spill.All used condoms should be wrapped in tissue or toilet paper and thrown in the bin. Condoms should not be flushed down the toilet as they may cause blockages in the sewage system. |
