It's a tpye of chemical reaction called a displacement reaction, it's alsoa redox reaction
This problem is a Double Reactant. "K+ H20 ----> KOH + H2" would equal "2K + 2H20 ---> 2KOH + H2"
2K+2HCl-->2KCl+H2

Yes it does so violently. 2K + 2HNO3 --> 2KNO3 + H2 + heat
It is a vigorous and exothermic reaction, in which a salt of Potassium and Hydrogen is produced. The heat produced may be enough to burn the hydrogen produced.

2K + 2HCl -> 2KCl + H2 hydrochloric acid would do here.
Balanced equation: 2 H2 + O2 --> 2 H2O
2K+ + 4H+ + 2O2- = 2K++ 2OH- + H2 Sodium is a reducing metal.
if you mean what the reaction is then... 2K + 2H2O --> H2 + 2KOH The products are hydrogen gas and potassium hydroxide.
2K(s) + 2H2O(l) -> 2KOH(s) +H2(g) However, if potassium were dropped into water, there would be so much water that the KOH would not be solid but aqueous so it should read 2K(s) + 2H2O(l) -> 2KOH(aq) +H2(g)
Potassium will react with nitric acid to produce potassium nitrate and hydrogen gas. 2K + 2HNO3 --> 2KNO3 + H2
