Sarin gas is a nerve gas that is considered a weapon of mass destruction. The use, production, and stockpiling of chemical weapons has been banned by international treaty due to the extremely painful death they cause. Nonetheless, some countries have stockpiles of sarin gas, which has been used on human populations on occasion. Sarin gas poisoning is difficult to treat because sarin forms a covalent bond with acetylcholinesterase, making it a/an.

The correct answer is powerful weapon

Sarin gas is a highly toxic gas, belonging to the group of organo-phosphorous, whose molecular formula is C4H10PFO2. It was discovered accidentally in 1936 by Gerhard Scharader, a German chemist, during a synthesis of pesticides. This gas is found in liquid or vapor form, has a sweet odor. Its melting point is -57 ° C, boiling point 147 ° C and density 1.089 g / mL. As it is a dangerous gas, there is no disclosure of its synthesis, because if this happens it can be manufactured and used inappropriately. The phosphoric acid (H3PO4) present in the Sarin gas molecule and the temperature, are factors that accelerate the reaction of the gas, causing it to become fast.
