displacement Reaction of metals

displacement Reaction of metals

Open Ended

what is the meaning of displacement ?

Multiple Choice

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

Multiple Choice

Which of the following is more reactive?

• Calcium

• Magnesium

• Zinc

• Magnesium

displacement reaction means

when more reactive metal push out less reactive metal from its compound

Example 1

Adding an iron nail to is added to a blue copper sulfate solution

Iron is more reactive than copper. A chemical change occurs. Iron atoms displace the copper atoms, bonding with the sulfate to make iron sulfate, which is a pale green solution. Reddy-brown Copper atoms form on the outside of the iron nail and some collect on the bottom of the beaker.  iron + copper sulfate => copper + iron sulfate

Multiple Choice

what are the product of the reaction between iron and Copper Sulfate ?

• copper +iron Sulfate

• no reaction

• iron copper + sulphate
