Summary of Reactions of Metals
Yoz,
Here's a summary I've gotten from Encarta.
Q1. In class, we have agreed that Hydrogen is placed above Cu since Cu is unable to displace it from the water, steam or acid. However, the observation reported by Encarta is different (see Pb). Why?
Q2. If Hydrogen were less reactive than Fe, why is it able to reduce Fe2O3? What conditions are required for the reduction to take place? What does this tells us about reactivity of Hydrogen? Would we then be able to use carbon to extract reactive metals from their ores?
Please give your comments.

Hi, i tink that carbon should be able to reduce some reactive metals, only those that are quite close to it, like Aluminium & Magnesium, maybe Calcium too, under very high temperature. I dunno lar... ...
To put carbon below aluminium and above zinc, we need to do some experiments right? Under what conditions are the reactions done?
