As rubidium is a group one element, it has only the 5s1 electron in its outer energy level which makes it very reactive. So, if we were to drop some rubidium in water it would react rapidly to produce smoke and small sparks.
There are lots of YouTube videos of this reaction so take a look.
It would catch fire and make Rb2O and zoom around in little circles
when a piece of rubidium were dropped in water then,then R2O and H2 will produce(rubidium oxide and hydrogen gas)
If you mean "What is the difference between rubidium and cesium?" then Rubidium and cesium are two different elements.They have similar properties but cesium is denser and has a higher atomic mass.Cesium also reacts more vigorously with water and air.
The most common set of metals that react with water at room temperature are the alkali metals, namely lithium, sodium, potassium, rubidium, cesium, and francium. while these metals react quite violently with water at room temperature, many if not most other metals have some sort of reaction with water at room temperature (IE, iron rusting in water)
The answer depends on the density as well as the shape of the 100 kg mass.
A piece of plastic over a boiling kettle will collect the steam (evaporated water) and it will condense.
cover slip is a small piece of glass which is used to cover.
Rubidium (Rb)
The word equation for the reaction of rubidium with water is rubidium + water --> rubidium hydroxide + hydrogen. Rubidium is a metal that reacts very quickly and fiercely, even explosively with water.
It will sink
when sodium is dropped into water sodium hydroxide is produced leaving out hydrogen.
Rubidium oxide react with water.
A water solution of Rubidium hydroxide
Yes. All rubidium compounds are water soluble.
rubidium + water ---> rubidium hydroxide + hydrogen 2Rb (s) + 2H20 (l) ---> 2RbOH (aq) + H2 (g)
The water turns purple, and gets hotter. And what happens to the beaker? Depending on what it is made of, and the temperature to which it is heated, it might melt.
Rubidium is highly reactive and if it is added to cold water there will be a large, exothermic reation; rubidium hydroxide and hydrogen are formed.
It will sink.
Rubidium reacts violently (and does not explode,) to produce Rubidium Hydroxide and Hydrogen.
