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.
