What did you find
out?
Was hydrogen able to
displace copper from it’s oxide?
What about iron,
zinc?
You should
have noted that hydrogen was able to displace only copper but
not iron nor zinc.
–Hydrogen + copper oxide ¾®
copper + water
–Hydrogen + iron oxide ¾® no reaction
–Hydrogen + zinc oxide ¾® no
reaction
Based on
these results, hydrogen can be placed between iron and copper in
the series.
