Chem equation K + H2O -->KOH + H2?

Question

K + H2O --> KOH + H2

Answer 1

K + H2O --> KOH +1/2 H2 or

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

the products are correct

Answer 2

Are you supposed to balance it?

if so....

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

Answer 3

2K(s) + 2H2O(l) --> 2KOH(aq) + H2(g)

Ionic equation

2K(s) + 2H2O(l) --> 2K+ + 2OH-  + H2(g)

Ok.  What's the question?  

There are pretty good reasons why this is not a recommended demonstration.  Potassium can easily form unstable peroxides and superoxides that can explosively decompose when cutting into a sample of potassium even if it has been stored in kerosene.

Answer 4

2K + 2H2O ==> 2KOH + H2
