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.
cold water is much heavier than hot water . the water becomes warm
Rubidium, Rhodium
water
the dead sea was once a 'normal' sea like the rest, but evapoation made a higher percentage of water disappear than normal seas so when that happens the salinity of the water increases the way the dead sea has gone. Its not that salt has been added from a mysterious source, it that water has been taken away.
The half-life isn't specified for an element, but for an isotope. Check the Wikipedia article titled "Isotopes of rubidium" for more details.Rubidium-87 occurs naturally; it has a half-life of 4.92×1010 years.
Rubidium is a large sized atom of alkali metals family and is highly reactive towards water when it is added in water Rubidium hydroxide is formed along with bubbles of hydrogen gas this hydroxide is strong alkali so pH value of water shows a change from 7 to 12 , 13 or 14.
The reaction is very exothermic.
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.
Rubidium oxide react with water.
A water solution of Rubidium hydroxide
Rubidium chloride, RbCl, should be formed.
The radius of strontium is smaller than the radius of rubidium.
happens
Yes. All rubidium compounds are water soluble.
rubidium + water ---> rubidium hydroxide + hydrogen 2Rb (s) + 2H20 (l) ---> 2RbOH (aq) + H2 (g)
FRb
The salt rubidium chloride is produced, along with considerable heat and light!
