Answer:

#2"K"_text((s]) + "H"_2"SO"_text(4(aq]) -> "K"_2"SO"_text(4(aq]) + "H"_text(2(g])#

Explanation:

Potassium metal will react with concentrated sulfuric acid to produce potassium sulfate, a salt that exists as potassium cations, #"K"^(+)#, and sulfate anions, #"SO"_4^(2-)# in solution, and hydrogen gas.

The balanced chemical equation for this reaction is

#2"K"_text((s]) + "H"_2"SO"_text(4(aq]) -> "K"_2"SO"_text(4(aq]) + "H"_text(2(g]) uarr#

This is a very strong redox reaction in which potassium is being oxidized and hydrogen is being reduced.
