Question

1
Metallic oxides of zinc, magnesium and copper were beated with the
following metals
Metal
Zinc
Magnesium Copper
Zinc oxide
Magnesium oxide
Copper oxide​

Answer 1

Answer:

magnesium will displace both zinc and copper

Answer 2

$\large{\underbrace{\sf{\red{ Required\:Answer :}}}}$

$\green{\underline\bold{We \:know\:that,}}$

A more reactive metal can displace a less reactive metal from it's oxide.

Keeping in mind that out of zinc, magnesium and copper metals, magnesium is the most reactive, zinc is less reactive whereas copper is the least reactive metal.

$\purple{\underline\bold{Displacement\: reactions \:will \:take\: place \:in \:the\: following\: cases:}}$
