Beryllium hydroxide
Beryllium chloride is formed with evolution of hydrogen gas. Be(s) + 2HCl(aq.) -------> BeCl2(aq.) + H2(g)
1.5
Beryllium arsenide, Be3As2; doubtful compound.
Beryl is exclusively of a pegmatite mineral. When this pegmatite magma has a rich source of beryllium, the beryl crystals are formed. They are formed in high temperature veins by these beryllium bearing gas content.
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.
barium hydroxide
Magnesium hydroxide, a precipitate, is formed.
No, they will not. Because the salt formed is Ammonium chloride, which is highly soluble in water. Only insoluble salts form a precipitate.
It is Iron III hydroxide (thats the brick red precipitate). It forms as well sodium chloride which is soluble in the water of the reaction and therefore you do not see.
Silver Chloride (AgCl) is the precipitate in this reaction.
Any precipitate is formed.
The insoluble in water copper(II) hydroxide is formed.
The precipitate formed is Calcium Carbonate (CaCO3).
Barium sulfate is the precipitate
In this reaction white precipitates of Silver chloride are formed.
Any reaction between sodium chloride and sodium hydroxide.
A white precipitate of mercury(I) chloride is formed when a small amount of tin chloride SnCl2 is put into a solution of mercury(II) chloride (HgCl2); adding more SnCl2 turns this precipitate black as metallic mercury is formed.
