• Iron oxide + copper oxide

• Iron oxide + copper

• Magic

Will the following reaction take place?

Ni + NaCl ->

• NO

• YES

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 the products of this reaction be?

calcium + zinc nitrate --------->

• Calcium + zinc nitrate

• Zinc + calcium nitrate

• there will be no reaction

• Zinc + calcium chloride

What are the products when magnesium reacts with hydrochloric acid?

• magnesium nitrate and hydrogen gas

• magnesium sulfate and hydrogen gas

• magnesium oxide and oxygen gas

• magnesium chloride and hydrogen gas

Which of the following will not undergo reaction?

• zinc metal  +  zinc oxide 
• iron metal  +  copper oxide
• zinc metal +  iron oxide
• magnesium  +  iron oxide

Select the best explanation for why there is no reaction between copper and magnesium sulphate.

• Copper is more reactive than magnesium so does not displace it.

• Copper is less reactive than magnesium so does not displace it.

• Copper is less reactive than magnesium so displaces it.

• Copper is more reactive than magnesium so displaces it.
