Reacting Carbon Dioxide with Lime water | Superprof
This happens as the carbon dioxide forms acidic carbonic acid when it dissolves in the water, the carbonic acid (H2CO3) reacts further with the calcium carbonate: CO2 + H2O ——> H2CO3H2CO3 +CaCO3 ——–> Ca(HCO3)2 Ca(HCO3)2 = calcium hydrogen
What Is a Metal Hydride? - ThoughtCo

It forms compounds (such as HCl and HNO 3) that are analogs of alkali metal compounds (such as NaCl and KNO 3). Under conditions of very high pressure, it has the properties of a metal. (It has been argued, for example, that any hydrogen present at the center of the planet Jupiter is likely to be a metallic solid.)
Peroxidase - an overview | ScienceDirect Topics
Peroxidase activity was discovered by Schonbein in 1855 when treating guaiacol with hydrogen peroxide and plant extracts. Peroxidases are found in all plants and animals, and are essential for living systems. 1 They alyze the abstraction of one or two electrons (usually two) via a single-electron transfer from an organic substrate, hydrogen peroxide being used as electron acceptor according
