G10 IGCSE Metals Quiz

Tin is a metal that is less reactive than iron and is extracted from its ore cassiterite, SnO₂.

Which statements about tin are correct?

1 Tin can be extracted from cassiterite using carbon.

2 Tin does not conduct electricity.

3 Tin is hard and shiny.

• 1, 2 and 3

• 1 and 2 only

• 1 and 3 only

• 2 and 3 only

Some chemical properties of three metals W, X and Y and their oxides are shown.

What is the order of reactivity of these metals, with most reactive first?

• W → Y → X

• X → Y → W

• Y → W → X

• Y → X → W

The list shows the order of reactivity of some elements.

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.

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

Which substances do not react together?

• calcium + water

• copper + dilute hydrochloric acid

• sodium + water

• zinc + dilute hydrochloric acid

W, X, Y and Z are four metals.

Some properties of these metals are listed below.

1 Only W and Z can be extracted by reduction of their oxides with carbon.

2 Only X will react with cold water.

3 Only Z can be found ‘native’ (not combined with any other element).

What is the correct order of these metals in the reactivity series (most reactive first)?

• X, W, Y, Z

• X, Y, W, Z

• Z, W, Y, X

• Z, Y, W, X

Samples of five different metals, E, F, G, H and J were reacted with dilute sulfuric acid using the apparatus shown.

The volume of hydrogen gas collected after one minute was measured.

The results are shown on the bar chart.

What is the order of reactivity of the metals (most reactive first)?

• E, F, G, H, J

• G, E, H, F, J

• J, F, H, E, G

• J, H, G, F, E

The statements describe how different metals react with cold water.

● Calcium sinks, fizzing and releasing a steady stream of hydrogen.

● Copper does not react.

● Sodium floats, fizzing and rapidly releasing hydrogen.

● Zinc does not react but does react with steam, releasing hydrogen.

Using the information, where should hydrogen be placed in the reactivity series

• below copper

• between sodium and calcium

• between calcium and zinc

• between zinc and copper

Metal X lies between zinc and iron in the reactivity series.

Which statements about metal X are correct?

1 It reacts with steam to produce hydrogen gas.

2 It does not react with steam but will produce hydrogen with dilute acid.

3 The metal can be obtained from its oxide by heating strongly with charcoal.

4 The metal oxide cannot be reduced using carbon.

• 1 and 3

• 1 and 4

• 2 and 3

• 2 and 4

The oxide of element X is reduced by heating with carbon.

Element X does not react with cold water, steam or dilute hydrochloric acid.

What is X?

• copper

• iron

• magnesium

• zinc
