Reactivity Series

Which of the following will react faster when heated

• Aluminium

• Ferum

• Zinc

• Lead

Answer explanation

you will need to memorise the reactivity series of metal. the higher the metal in the series, the more reactive the metal

What are the two non-lethal elements that are included in the reactivity series of metals

• Carbon

• Hydrogen

• Silver

• Gold

Where we should keep those metal

• In an air tight container

• In a vacuum chamber

• In paraffin oil

• In dilute sulphuric acid

Which of the following metals, located below hydrogen in the reactivity series, do not react with steam?

• gold

• silver

• copper

• lead

Which description best fits the reaction of metals with a dilute acid as you go down the reactivity series?

• React less vigorously

• React more vigorously

• React less vigorously. Below hydrogen there is no reaction

• React less vigorously. Below carbon there is no reaction

The list shows the order of reactivity of some elements.
K Na Ca Mg Zn Fe (H)
Which statement about the reactivity of these metals is correct?

• Copper reacts with steam to form hydrogen gas.

• Magnesium is more reactive than calcium.

• Potassium reacts with water to form hydrogen gas.

• Sodium oxide is reduced by carbon to sodium.

Answer explanation

Copper does not react with steam.

Magnesium is below calcium in the reactivity series.

Carbon is below sodium in the reactivity series, therefore it cannot reduce sodium ions.

The diagrams show what happens when three different metals are added to water. What are X, Y and Z?

• X - Calcium

  Y - Copper

  Z - Potassium

• X - Copper

  Y - Calcium

  Z - Potassium

• X - Potassium

  Y - Calcium

  Z - Copper

• X - Potassium

  Y - Copper

  Z - Calcium

Answer explanation

Copper does not react with water

Calcium reacts with cold water, but not violently

Potassium reacts with cold water violently

Metal X lies between zinc and iron in the reactivity series. Which statements about metal X are correct?

• and 3

• and 4

• 2 and 3

• 2 and 4

Answer explanation

Zinc and Iron both react with steam.

Metals below carbon in the reactivity series can be reduced by carbon (charcoal).
