Schedule 3 substances, in the sense of the Chemical Weapons Convention, are chemicals which have large-scale industrial uses, but are feasible to use as toxic chemical weapons (Part A) or manufacturing precursors (Part B).
The Lists themselves are divided into part A with toxic substances that can be used directly as chemical weapons and part B containing their precursors (chemicals with which those substances can be made). The Lists are subject to the following criteria, among others: [2] [3] Schedule 1 [4] contains substances most clearly related to a chemical ...
Class 3: Flammable Liquids A flammable liquid is a liquid having a flash point of not more than 60 °C (140 °F), or any material in a liquid phase with a flash point at or above 37.8 °C (100 °F) that is intentionally heated and offered for transportation or transported at or above its flash point in a bulk packaging.
Schedule 2 substances, in the sense of the Chemical Weapons Convention, are chemicals that are feasible to use as chemical weapons themselves (Part A), or their manufacturing precursors (Part B), and which have small-scale applications outside of chemical warfare and so can be legitimately manufactured in small quantities.
A period 3 element is one of the chemical elements in the third row (or period) of the periodic table of the chemical elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic number increases: a new row is begun when chemical behavior begins to repeat, meaning that elements with similar behavior fall into ...
Sodium nitrate is the chemical compound with the formula Na N O 3.This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
The chemical formula for ozone, O 3, was not determined until 1865 by Jacques-Louis Soret [15] and confirmed by Schönbein in 1867. [ 10 ] [ 16 ] For much of the second half of the 19th century and well into the 20th, ozone was considered a healthy component of the environment by naturalists and health-seekers.
