This is the list of Schedule II controlled substances in the United States as defined by the Controlled Substances Act. [ 1] The following findings are required for substances to be placed in this schedule: [ 2] The drug or other substance has a high potential for abuse. The drug or other substance has a currently accepted medical use in ...
The Schedule 2 list is one of three lists. Chemicals that can be used as weapons, or used in their manufacture, but that have no, or almost no, legitimate applications as well are listed in Schedule 1, whilst Schedule 3 is used for chemicals that also have widespread industrial uses. The use of Schedule 1, 2, or 3 chemicals as weapons is banned ...
Oxygen compounds. Water (H 2 O) is the most familiar oxygen compound. The oxidation state of oxygen is −2 in almost all known compounds of oxygen. The oxidation state −1 is found in a few compounds such as peroxides. Compounds containing oxygen in other oxidation states are very uncommon: − 1⁄2 ( superoxides ), − 1⁄3 ( ozonides ), 0 ...
In chemistry and biology, reactive oxygen species ( ROS) are highly reactive chemicals formed from diatomic oxygen ( O2 ), water, and hydrogen peroxide. Some prominent ROS are hydroperoxide (O 2 H), superoxide (O 2- ), [ 1] hydroxyl radical (OH. ), and singlet oxygen. [ 2] ROS are pervasive because they are readily produced from O 2, which is ...
Water-reactive substances[ 1] are those that spontaneously undergo a chemical reaction with water, as they are highly reducing in nature. [ 2] Notable examples include alkali metals, lithium through caesium, and alkaline earth metals, magnesium through barium . Some water-reactive substances are also pyrophoric, like organometallics and ...
Water splitting is the chemical reaction in which water is broken down into oxygen and hydrogen: [ 1] 2 H 2 O → 2 H 2 + O 2. Efficient and economical water splitting would be a technological breakthrough that could underpin a hydrogen economy. A version of water splitting occurs in photosynthesis, but hydrogen is not produced.
Chemical structure of water, the simplest hydrogen polyoxide. Hydrogen polyoxides (also known as oxidanes, oxohydrogens, or oxyhydrogens) are chemical compounds that consist only of hydrogen and oxygen atoms, are bonded exclusively by single bonds (i.e., they are saturated ), and are acyclic (have molecular structures containing no cycles or ...
Schedule 1 substances shall not be produced, acquired, retained or used at all by State Parties outside their territories, except in limited quantities for research, medical or protection purposes. [5] Schedule 2 [6] contains substances that pose a significant risk for use as a chemical weapon, or as a precursor of a substance from List 1 or ...
