If the metal is more reactive than the metal in the compound it completes with the less reactive metal. Therefore, it can concluded that ...
The less reactive metal repel the more reactive metal from its compound
The less reactive metal pushes out or displaces the more reactive metal from its compound
The more reactive metal bonded with the less reactive metal from its compound
The more reactive metal pushes out or displaces the less reactive metal from its compound
What will be reaction if less reactive metal is added in a solution with more reactive metal compound?
vigorous reaction
burns moderately
fizzing gas produced
no reaction
The reaction of chlorine with iron can be demonstrated by passing chlorine over iron wool in a tube. The tube has an open end to allow unreacted chlorine to escape. The iron wool is heated as the chlorine is passed over it.
State why this reaction should be carried out in a fume cupboard
chlorine is toxic
iron is heavy enough
chlorine is volatile
iron is dangerous
A galvanised metal is one which has been covered wit
iron
calcium
copper
zinc
