Antoine Lavoisier publishes Traité Élémentaire de Chimie, the first modern chemistry textbook. It is a complete survey of (at that time) modern chemistry, including the first concise definition of the law of conservation of mass, and thus also represents the founding of the discipline of stoichiometry or quantitative chemical analysis.

The Jiffy is the amount of time light takes to travel one femtometre (about the diameter of a nucleon). The Planck time is the time that light takes to travel one Planck length. The TU (for time unit) is a unit of time defined as 1024 μs for use in engineering. The svedberg is a time unit used for sedimentation rates (usually
Before Present (BP) or "years before present (YBP)" is a time scale used mainly in archaeology, geology, and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s.
Another type of timeline is used for project management. Timelines help team members know what milestones need to be achieved and under what time schedule. An example is establishing a project timeline in the implementation phase of the life cycle of a computer system.
Timelines describe the events that occurred before another event, leading up to it, causing it, and also those that occurred right afterward that were attributable to it. . Timelines are often bulleted lists or tabl
'Lessons in Chemistry,' starring Brie Larson, drops new episodes on Apple TV+ every Friday until the November 24 finale. Here's a look at the release date schedule.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
