The experiment aimed to illustrate periodic trends in the alkali metal series. It showed the violent reactions of metallic sodium and potassium with water, in which the hydrogen produced subsequent explosions, and intended to demonstrate the even greater reactivity of rubidium and caesium by dropping them into a water-filled bathtub. The ...
Alkali metals dropped into a bathtub filled with water will create a huge explosion. Busted Tory, Grant, and Kari went to the Alameda County bomb range to test the myth, which is featured in an episode of the British TV show Brainiac: Science Abuse.
The alkaline earth metals (Be, Mg, Ca, Sr, Ba, and Ra) are the second most reactive metals in the periodic table, and, like the Group 1 metals, have increasing reactivity with increasing numbers of energy levels. Beryllium (Be) is the only alkaline earth metal that does not react with water or steam, even if the metal is heated red hot. [9]
The alkali metals also react with water to form strongly alkaline hydroxides and thus should be handled with great care. The heavier alkali metals react more vigorously than the lighter ones; for example, when dropped into water, caesium produces a larger explosion than potassium if the same number of moles of each metal is used.
Does dropping alkali metals in a water-filled bathtub result in a huge explosion? Does brandy, such as carried by Saint Bernards, really prevent hypothermia? Does lighting a piano on fire make it explode? Note: This is a special episode.
Here's another item to add to the list of things you shouldn't try at home: tossing your plastic water bottle into molten hot steel.
Mason, on his own and with some fellow technical workers, did original physical chemistry research into the nature of the alkali metals (sodium and potassium, for example) and their chemistry with oxygen and water. [6] It has been known since the metals could be obtained in pure forms that they are explosive when dropped into water.
In thermodynamics, an exothermic process (from Ancient Greek έξω (éxō) 'outward' and θερμικός (thermikós) 'thermal') [1] is a thermodynamic process or reaction that releases energy from the system to its surroundings, [2] usually in the form of heat, but also in a form of light (e.g. a spark, flame, or flash), electricity (e.g. a ...
