We want to give students and teachers whose schools closed because of Covid-19 free access to Waltzing Atoms. If you are interested please get in touch with us #letswaltz#learning#chemistry#covid19
ACHTUNG: Durch die Schulschließungen aufgrund des Covid19-Virus wird die Einreichfrist auf 30.04.2020 verlängert. Sollten sich die Schließungen verlängern, kann es weitere Verschiebungen geben.
What do bleached hair and white paper have in common? Both probably have been in contact to hydrogen peroxide (H2O2). The majority of the H2O2 production is used for pulp- and paper-bleaching. #letswaltz#chemistry https://t.co/sGfUAxhbuU
In sulfuric acid (H2SO4), 4 oxygens are stealing electrons from the sulfur. What is the oxidation number for sulfur? #letswaltz#chemistry#OxidationStates https://t.co/sGfUAxhbuU
Atoms living alone are neutral, but when other elements start to bind, charge gets distributed unevenly among them. Oxidation states are a way to understand and describe this unevenly distributed electrons in a molecule. #letswaltz#chemistry https://t.co/sGfUAxhbuU
Vanillin is a phenolic aldehyde. It is the primary component of the extract of the vanilla bean. In 2007 the Ig Nobel Chemistry Prize was awarded to Mayu Yamamoto for her work in extracting vanillin from cow dung. #letswaltz#chemistry#christmas https://t.co/sGfUAxhbuU
Watch the very moment the 2019 Chemistry Laureates - John B Goodenough, Stanley Whittingham and Akira Yoshino - collect their #NobelPrize medals and diplomas. Congratulations!
Eugenol is the primary compound in cloves, imparting a spicy, aromatic flavor. Cloves are one of the key spices required for the making of mulled wine. #letswaltz#chemistry#christmas https://t.co/sGfUAxhbuU
