The exothermic reaction is the crystallisation of sodium ethanoate, and the endothermic reaction is the reaction of barium hydroxide with ammonium chloride. Jon describes an easy way to remember ...

When ammonium chloride powder is mixed with barium hydroxide powder and stirred, a chemical reaction takes place. The temperature drops to –14°C. True or false? This is an exothermic reaction.

Strange, ultraheavy stars that are rich in barium grow massive by cannibalizing their companions, scientists discover after finally catching these stellar leeches in the act. A strange type of ...

Inhaled anesthetic agents include nitrous oxide (the oldest of all anesthetics) and various halogenated agents: desflurane (halogenated solely with fluorine halogenation increases potency and is ...

Magnesium reacts exothermically with most acids, and with water at room temperature to give magnesium hydroxide and hydrogen. It is a very flammable metal, able to burn in both nitrogen and carbon ...

It was this terminology that inspired Sir Humphrey Davy to call the element sodium when he first isolated it by passing an electric current through caustic soda, or sodium hydroxide, in 1807. This ...

In essence, salt water (brine, NaCl) is split through electrolysis to generate caustic soda (Sodium Hydroxide, NaOH), Chlorine gas (Cl2) and Hydrogen (H2) gas. Inorganic synthesis, the process of ...

Current research involves encapsulation of flocs based on iron hydroxide and barium carbonate, and the corrosion of various metals stored in highly alkaline conditions. Another current interest is in ...
