Reactivity Series & Rate of Reaction

Based on the diagram above, which metals are more reactive?

• Red zone

• Yellow zone

• Green zone

If I have metal from the yellow zone (e.g. Iron oxide), for a displacement reaction to occur, I need to add a metal from which zone?

• All metals in the red zone

• All metals in the yellow zone

• All metals in the green zone

If I have a copper sulfate, which statements below are correct? (Tick more than 1)

• Addition of gold will be resulting gold sulfate

• If it reacts with aluminum, it will be resulting aluminum sulfate

• Its reaction with calcium is not be considered as a displacement reaction

• Lead sulfate will be formed during the reaction if some masses of lead is added

Aluminum will be formed from Aluminum Oxide if it is being reacted with these metals (Tick more than 1)

• Iron

• Nickel

• Magnesium

• Zinc

• Sodium

Zinc Carbonate will be formed if Zinc is being reacted with?

• Calcium Carbonate

• Magnesium Carbonate

• Lead Carbonate

• Potassium Carbonate
