41–50 of 66 · Easy
Question 41
1 mark · Easy
Answer and see the solution →Rubidium is placed above potassium in the reactivity series. Would you expect rubidium to react more or less vigorously with water compared to potassium? State your answer.
Question 42
3 marks · Easy
Answer and see the solution →Calcium, lead and iron are placed in the following order in the reactivity series: calcium > iron > lead.
(a)[1 mark]Which of these three metals would you expect to react most quickly with dilute hydrochloric acid?
(b)[1 mark]Predict which of these metals would not react at all with cold water.
(c)[1 mark]Explain your answer to part b.
Question 43
2 marks · Easy
Answer and see the solution →A lump of nickel is placed in copper(II) sulfate solution. Explain what happens, using the reactivity series.
Question 44
3 marks · Easy
Answer and see the solution →A student investigates the reaction of four metals (A, B, C, D) with dilute hydrochloric acid. The results are given in the table:
Observed reactions with dilute hydrochloric acid. Metal Observation A rapid fizzing B no reaction C slow bubbling D moderate fizzing (a)[1 mark]Arrange the metals in order of decreasing reactivity with dilute hydrochloric acid.
(b)[1 mark]Which metal is most likely copper? Explain your answer.
(c)[1 mark]Suggest a possible identity for the most reactive metal, A.
Question 45
2 marks · Easy
Answer and see the solution →Gallium is a metal that is placed between aluminium and zinc in the reactivity series. Copper is below both aluminium and zinc in the reactivity series.
Predict whether gallium will be able to displace copper from copper(II) sulfate solution. Use the reactivity series to explain your reasoning.
(a)[2 marks]Will gallium displace copper from copper(II) sulfate solution? Explain your answer using the reactivity series.
(b)[0 marks]Question 46
1 mark · Easy
Answer and see the solution →A piece of rubidium metal is added to cold water. Predict what will happen. Use the reactivity series in your answer.
Question 47
3 marks · Easy
Answer and see the solution →A new metal, Q, lies between magnesium and zinc in the reactivity series.
(a)[1 mark]Predict whether metal Q will react with cold water. State your reasoning.
(b)[2 marks]Predict whether metal Q will react with dilute hydrochloric acid at room temperature. State your reasoning.
Question 48
2 marks · Easy
Answer and see the solution →When 1.0 g of an unknown metal (X) is added to excess dilute sulfuric acid at room temperature, 0.067 g of hydrogen gas is released. Given that the metal is above hydrogen in the reactivity series, predict whether magnesium or iron is more likely to be metal X. Show your reasoning.
Question 49
1 mark · Easy
Answer and see the solution →State what forms on iron when it rusts.
Question 50
3 marks · Easy
Answer and see the solution →The picture below shows a steel fence post that has rusted at the base after several years in a damp garden.
(a)[2 marks]State two conditions necessary for rusting to occur on the steel post.
(b)[1 mark]Name one method, other than painting, which could have prevented rusting of the steel post.
