Water does not react with krypton, as krypton is a noble gas that is inert and does not readily form chemical compounds with other elements.
Alkali metals reacts violently with water forming a hydroxide and hydrogen; alkali earth metals react with water but no so violent.Other metals doesn't generally react with water at room temperature.
Potassium generally reacts more readily with nonmetals than with metals due to its strong tendency to donate its outer electron. This results in the formation of ionic compounds with nonmetals. Potassium can also react with metals, but nonmetal reactions are often more vigorous.
Nonmetals bonding with other nonmetals most often result in covalent bonds.
It fizzes.

it blows up
Hydrogen does not react with water
When potassium reacts with water, it forms potassium hydroxide and releases hydrogen gas. When potassium reacts with oxygen, it forms potassium oxide.
The sodium methoxide reacts with the water to produce sodium hydroxide an methanol.
Copper sulfate is dissociated in water.
it reacts with water. it forms OH- by reaction.
It reacts violently, fizzes about on the surface and then: BOOM!!!
Copper Oxide reacts with Sulphuric acid to form Copper Sulphate and Water.
Uranium reacts well with most nonmetals and their compound's. Very simple.
Sulphurous acid is formed H2O + SO2 ----> H2SO3
the glass tank explodes!xd
