Which metal is more reactive than calcium?

• magnesium

• potassium

• silver

• aluminum

A displacement (single replacement) 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

Which one of the following would result in a displacement reaction?

• Iron with magnesium chloride

• magnesium with iron chloride

• Iron with Zinc Sulphate

• gold with silver nitrate

Calcium + zinc nitrate reacts to form

• Calcium + zinc nitrate

• Zinc + calcium nitrate

• there will be no reaction

• Zinc + calcium chloride

Which of the following will not undergo reaction?

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

When magnesium reacts with copper sulphate, there are two products. What are they?

• Magnesium  and Copper
• Magnesium Sulphate and Copper
• Magnesium Sulphate and Copper Sulphate
• Magnesium and Copper Sulphate

When copper and magnesium sulphate are mixed together, there is no reaction. Why?

• Magnesium is more reactive than copper
• Copper is more reactive than magnesium
• Copper never reacts with metal salts
• Magnesium Sulphate never reacts with metals

What will be the result when sodium is combined with potassium chloride?

• no reaction

• sodium chloride + potassium

• sodium chloride + potassium chloride

• sodium + potassium

What will be the result of iron + lead nitrate?

• iron nitrate + lead

• no reaction

• iron nitrate + lead nitrate

• iron + lead

Metal A is more reactive than Metal B. The following displacement reaction takes place.

Metal A + Metal B in compound ---> Metal B + Metal A in compound.

True or False.

• True

• False
