Na + H2O reaction
«

What exactly happens, I know that the sodium removes hydrogen... but is the balanced equation:
2Na + H
2
O ---> H
2
+ Na
2
O
or
2Na + 2H
2
O ---> H
2
+ 2NaOH
Just a random question I was curious about.

your 2nd reaction is correct.

metal + water will react according to an redoxreaction:
meta --> metalion + e-
2H2O + 2e- --> H2 + 2OH(-)

That's what I thought. But I was told that the first reaction was correct.

it's correct too but remember that Na2O in H2O will react in an acid-base-reaction due to the O(2-)-ions:
O(2-) + H2O --> 2OH(-)
thus in a solution:
Na2O + H2O --> 2 NaOH
the total nett reaction will then become the same as the first reaction.
