The rubidium reacts violently, producing hydrogen gas and a rubidium salt. If oxygen is present the heat from the reaction may ignite the hydrogen.
The radius of strontium is smaller than the radius of rubidium.
The salt rubidium chloride is produced, along with considerable heat and light!
Rubidium Hydroxide (RbOH) is a weak base.
It is the Rubidium salt of boric acid and is soluble in water.
Jade is not soluble in vinegar.
An acid
The acid becomes diluted.
Rubidium chloride, RbCl, should be formed.
Nothing happens. Gold will not react with sulfuric acid.
The radius of strontium is smaller than the radius of rubidium.
The temperature of the acid will increase
FRb
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.
The salt rubidium chloride is produced, along with considerable heat and light!
dissolve
depending on the kind of acid and the metal, corrosion may occur
put it in water
