Na (s) + H_2O (l) yields ? My main thing is I can't figure out if sodium reacts with water to produce sodium hydroxide, and if it does do that I am having trouble balancing it. If it doesn't react does that mean that there is no reaction b/c i know since sodium is a solid it won't break up into its ions unless it reacts with an ion in aqueoues solution in the activity series. So any help will be greatly appreciated b/c as you can see i'm not so sure.

2Na + 2H2O -> 2NaOH + H2
the reason being why sodium reacts with water to give sodium hydroxide is because sodium is very high up in the reactivity series, once in contact with moisture will result in explosion/vigorous reaction. therefore it is kept in oil when not in use.
well dun ask me why, i havnt learn till tt part. just memorize it bahx.

Na(s) is very reactive with water and even air. Metals + water -> H2 gas + alkali.
So, 2Na(s) + 2H2O (l) -> 2NaOH(aq) + H2(g)
Quoted: "reacts with an ion in aqueoues solution in the activity series" -- u're talking abt displacement reaction. The Na + H2O is a redox reaction, not a displacement reaction.

2Na +H20 ---> 2 Na OH +H2

2Na + 2H2O---------------2NaOH + H2
