Of course you can reduce ZnO, but in high temperature in which Zn will react with one product of reaction, namely H2O.
Many metals that resist reduction by carbon can be reduced by heating in a stream of hydrogen, the constant motion pushes gaseous products away.
Sorry, I don't understand why either of those statements are true.
My understanding of the relative reactivity of Zinc, Hydrogen and Carbon is summarised in the following diagramhttp://www.gcsescience.com/r1-reactivity-series-metals.htm
From which I understand Carbon can reduce Zinc oxide to zinc because carbon is more "reactive" than zinc
But hydrogen CANNOT reduce Zinc oxide to zinc because hydrogen is much less "reactive" than zinc.
How can changing the reaction conditions such as streaming hydrogen over the oxide have any effect on the reactivity? Why does reacting ZnO with H2
at high temperature have any impact?
Could you explain
in high temperature in which Zn will react with one product of reaction, namely H2O.
a little more as I don't understand what you have written
