At O level:Originally posted by Qex:hi I wanna ask huh
2 Na + 2 H2O -----> 2 NaOH + H2
How come sodium reacts with water is this equation huh?
Shouldnt it be
2Na + H20 -------> NaO + H2 ??
why must put coefficient of 2 in front?
The first chemical equation is for H2O(water), which will produced Sodium hydroxide and hydrogen gas.Originally posted by Qex:hi I wanna ask huh

At O level:
Sodium react with [b]Steam, H2O(g)
Na(s) + H2O(g) -> NaO(s) + H2(g)
Sodium react with (Cold) water, H2O(l)
2Na(s) + 2H2O(l) -> 2NaOH(aq) + H2(g)
This has been discuss many times already due to the complexity and complication at higher level, so for O level.. this will be it.[/b]
I created careless mistake.Originally posted by Hocklez:you created NaO?
not all lehOriginally posted by gunner77:metal react with water give u metal hydroxide lor
only grp I metal react wif water give u hydroxideOriginally posted by wishboy:not all leh
those with reactivity below that of sodium wont give that reaction
u know it happens but u donno why it does happen this way...Originally posted by Darkness_hacker99:Aiyo all..
This question has been discuss many times already.![]()
