Trichlorofluoromethane, also called freon-11, CFC-11, or R-11, is a chlorofluorocarbon (CFC). It is a colorless, faintly ethereal, and sweetish-smelling liquid that boils around room temperature. [5] CFC-11 is a Class 1 ozone-depleting substance which damages Earth's protective stratospheric ozone layer. [6]
Class I – Rations – Subsistence (food and drinking water), gratuitous (free) health and comfort items. Class II – Clothing And Equipment – individual equipment, tentage, some aerial delivery equipment, organizational tool sets and kits, hand tools, unclassified maps, administrative and housekeeping supplies and equipment.
Schedule 1 phosphonofluoridates; where R1 = (cyclo)alkyl with C < C 10 and R2 = Me, Et, i-Pr or n-Pr. The following criteria shall be taken into account in considering whether a toxic chemical or precursor should be included in Schedule 1: It has been developed, produced, stockpiled or used as a chemical weapon as defined in Article II;
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Chemical Illicit drug Phenyl-2-nitropropene: substituted amphetamines: 1-(4-bromophenyl)propan-1-one substituted cathinones and substituted amphetamines: 1-(4-chlorophenyl)propan-1-one substituted cathinones and substituted amphetamines: 1-(4-methylphenyl)propan-1-one substituted cathinones and substituted amphetamines: Carbonyldiimidazole: LSD
Others from this series were Perklone (Tetrachloroethylene), Triklone (Trichloroethylene), Methoklone (Dichloromethane) and Genklene (1,1,1-Trichloroethane). [15] [16] CFC-113 is one of the three most popular CFCs, along with CFC-11 and CFC-12. [17] CFC-113 in laboratory analytics has been replaced by other solvents. [18]

General chemistry (sometimes referred to as "gen chem") is offered by colleges and universities as an introductory level chemistry course usually taken by students during their first year. [1] The course is usually run with a concurrent lab section that gives students an opportunity to experience a laboratory environment and carry out ...
