Potassium plus oxygen equals

Answer 1

It equals into hydrogen gas (which is automatically ignited by the reaction's heat) and potassium hydroxide, which is instantly dissolved in the unreacted water.

It doesn't equal the world's safest reaction, however. Wear safety goggles and the proper gear.

Answer 2

You don't have to, should not, it is not possible to, are not able to ...

and so you must not MIX solid potassium metal with water!

It is already very dangerous, uncontrolably reacting when immersed in water and this should NEVER be tried at home. Hydrogen gas is (explosively) freed from it.

2K + 2H2O --> H2 + 2K+ + 2OH-

Answer 3

Potassium reacts with water to yield potassium hydroxide and hydrogen.

2K + 2H2O --> 2KOH + H2

The heat from this reaction will likely ignite the escaping hydrogen.

Answer 4

potassium reacts with water to give the hydroxide and hydrogen. the hydrogen is what burns while potassium gives a violet colour to the flame.

2 K + 2 H2O --> 2 KOH + H2

Answer 5

potassium oxide

Answer 6

KOH

Answer 7

KOH + H2
