Sodium would react very quickly with water to produce hydrogen gas in an exothermic reaction (a reaction that transfers energy to the surroundings). This would happen whenever the cutlery was put ...

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...

The reaction of the potassium with water is similar to the reaction of sodium in water but hotter. The demonstration shown in this video is very dangerous. Do not attempt to perform this demonstration ...

Miss Fong: Yes. Let's imagine we are mixing a common acid like nitric acid and a common alkali - sodium hydroxide. When they react water and a salt called sodium nitrate is produced. Katie ...

Commercial heat packs (containing iron and water, or supersaturated sodium acetate) and cold packs (various ammonium salts) can be used to show exo- and endothermicity. Heat packs that contain iron ...
