A displacement reaction will occur when...

• a more reactive metal displaces a less reactive metal from its compound.
• A less reactive metal displaces a more reactive metal from its compound
• Displacement only occurs when two of the same metals are reacted 
• Displacement reactions will only occur in metals above iron in the reactivity series

What will be the result if a less reactive metal is added in a solution with more reactive metal compound?

• vigorous reaction
• fizzing gas produced
• burns moderately
• no reaction
