and wat the helll is batani7? never heard abt that :-/

i'm srry abt batani7 , it's actually an arabian MSN word ...srry i though u were arabian :(....my bad :-[
as for the oxides ....i guess i just wanna to know where is hydrogen in the reactivity series........ actually the whole reactivity series ..i want it all .... can u give me a link that shows the reactivity series ...includin carbon and hydrogen ....cuz the one i have doesn't have hydrogen ....no idea y?!?!
as for the oxides .....i don't kno who reacts with what to give for ex hydrogen ,u see

Only a metal compound higher than Hydrogen can displace it from steam and hence form METAL OXIDE and STEAM

Ghost Of Highbury:
the link, here : http://www.zephyrus.co.uk/thereactivityseries.html
and abt the reactions, im still not sure wat u want.
"who reacts to what" completely depends on the q. like here.
steam reacted with a metal i.e iron
Steam - H2O
iron - Fe
H2O + Fe --> FeO + H2.
Iron displaced Hydrogen.
