Reactivity Series Quiz

In the construction of a spacecraft, engineers including Kira and Aleksey need to select a metal for the outer layer that is more reactive than Aluminium but less reactive than Calcium. Which metal should they choose?

• Gold

• Magnesium

• Zinc

• Iron

What happens when a piece of zinc is placed in a copper sulfate solution during Yuriy's chemistry experiment?

• No reaction occurs.

• The copper becomes more reactive.

• The zinc replaces the copper.

• The solution turns into pure water.

Imagine Anastasiia and Artem are chemists and they need to choose metals for a series of experiments based on their reactivity. Which of the following sequences correctly represents the order from most to least reactive metals?

• Sodium, Magnesium, Zinc, Iron

• Iron, Zinc, Magnesium, Sodium

• Magnesium, Iron, Sodium, Zinc

• Zinc, Iron, Sodium, Magnesium

Imagine Aleksey and Yuriy observing a piece of sodium reacting vigorously with cold water in a laboratory, producing sodium hydroxide and hydrogen gas. Based on this reaction, where would sodium likely be in the reactivity series?

• At the very bottom

• In the middle

• Near the top

• Not on the series

Imagine Mariia is in a chemistry lab and she has four different metal samples. She decides to test their reactivity by adding dilute hydrochloric acid to each. Which metal sample would not react with the acid?

• Potassium

• Sodium

• Copper

• Magnesium

Imagine Safiie has a piece of potassium, a metal high up in the reactivity series. What would be its main characteristic?

• It does not corrode easily.

• It is less likely to form compounds.

• It reacts vigorously with water and acids.

• It is used to make jewelry.

Imagine Taras has a piece of zinc metal and he drops it into a copper sulfate solution. What is meant by a displacement reaction in this context?

When magnesium ribbon is burned in air, it reacts with oxygen to form magnesium oxide, releasing heat in the process. Anastasiia and Kyrylo observed a temperature increase during the experiment. Place a tick if their observation is correct.

• True

• False

Imagine you are a chemist working in a laboratory alongside Marria and Artem. You have been given a task to complete the displacement reactions for a series of chemical compounds. How would you proceed with Marria and Artem to ensure a successful experiment?

What does an electromagnet in a scrapyard crane, similar to the one Alisa and Kira saw on their field trip, require to lift cars?

• Water

• Electricity

• Sunlight

• Wind
