The Oder (/ ˈ oʊ d ər / OH-dər [a]; Czech and Polish: Odra [b]) is a river in Central Europe.It is Poland's second-longest river and third-longest within its borders after the Vistula and its largest tributary the Warta. [1]
The West German definition of the "de jure" borders of Germany was based on the determinations of the Potsdam Agreement, which placed the German territories (as of 31 December 1937) east of the Oder–Neisse line "under the administration of the Polish State" while "the final delimitation of the western frontier of Poland should await the peace ...
In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms.
Valence shell electron pair repulsion (VSEPR) theory (/ ˈ v ɛ s p ər, v ə ˈ s ɛ p ər / VESP-ər, [1]: 410 və-SEP-ər [2]) is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms. [3]
For people living in the medieval Northern Holy Roman Empire and its precursors, especially for the Saxons, a Wend (Wende) was a Slav living in the area west of the River Oder, an area later entitled Germania Slavica, settled by the Polabian Slav tribes (mentioned above) in the north and by others, such as the Sorbs and the Milceni, further ...
A river is a natural freshwater stream that flows on land or inside caves towards another body of water at a lower elevation, such as an ocean, lake, or another river. A river may run dry before reaching the end of its course if it runs out of water, or only flow during certain seasons.
Poland's prime minister said Friday that “huge amounts of chemical waste” were probably dumped intentionally into the Oder River, which runs along the border with Germany, causing ...
The Taft equation is a linear free energy relationship (LFER) used in physical organic chemistry in the study of reaction mechanisms and in the development of quantitative structure–activity relationships for organic compounds. It was developed by Robert W. Taft in 1952 [2] [3] [4] as a modification to the Hammett equation. [5]
