Chem equation.. needs balancing.. is this correct?

Question

If not, please show me the answer.

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

Answer 1

Your answer is perfectly correct. The middle bit..'KOH + H2'

shouldn't be there..

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

(s) = solid; (l) = liquid; (aq) = aqueous solution; (g) = gas.

Answer 2

Write the answer as-

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

Written the way you write it means-

2K + 2H2O --> KOH + H2 (but this sn't correct; not balanced)

and-

KOH + H2 --> 2KOH + H2 (but this isn't correct; not balanced)

Answer 3

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

Your final answer is correct. Do not show the middle section, since the law of conservation of mass states that there must be the same number and kind of atoms on each side. In your equation there are not.
