(a) Which metal is extracted from bauxite ore? (b) Give the name of one ore of iron. Which iron compound is preent in this ore? Write its chemical formula. (c). Describe the extraction of zinc metal from its sulphide ore (zinc blende). Write equations of the reactions involved. (d) Explain why, the galvanised iron article is protected against rusting even if the zinc layer is broken. (e) name a common metal which is highly resistant to corrosion.

Which metal is highly resistant to corrosion?

A common metal which is highly resistant to corrosion is:

A metal which is resistant to corrosion is________

Which of the following elements is highly resistant to corrosion ?

The metal which is highly reactive

A metal X which is resistant to corrosion is produced by the electrolysis of its molten oxide whereas another metal Y which is also resistant to corrosion is produced by the reduction of its oxide with carbon. Metal X can be used in powder form in thermite welding whereas metal Y is used in making cathodes of ordinary dry cells. (a). name the metals X and Y. (b) Which of the two metals is more reactive: X or Y? (c) Name one ore or metal X. also write its chemical formula. (d) name one ore of metal Y. also write its chemcial formula. (e) name one alloy of metal X and one alloy of metal Y.
