Question 41
4 marks · Normal
Answer and see the solution →A student observes the reaction between four different metals and dilute hydrochloric acid. She records the following results:
Metal Observation Calcium Rapid bubbling; white suspension forms; test-tube gets hot Iron Slow fizzing; pale green solution; little heat noticed Zinc Steady bubbles; colourless solution; test-tube gets warm Gold No reaction; no observable change (a)[2 marks]Which metal, from the table, is the most reactive? Explain your answer.
(b)[2 marks]Explain why gold does not react with dilute hydrochloric acid.
Question 42
2 marks · Normal
Answer and see the solution →Potassium, magnesium, and copper are three metals in the reactivity series.
State which one you would expect to react most vigorously with dilute sulfuric acid. Explain your answer.
Question 43
4 marks · Normal
Answer and see the solution →Molybdenum (Mo) is a metal that lies between zinc and copper in the reactivity series.
(a)[2 marks]Predict whether molybdenum will react with dilute hydrochloric acid at room temperature. Explain your answer.
(b)[2 marks]Molybdenum metal is placed in a solution of silver nitrate.
State whether a reaction will occur and write a balanced equation for the reaction, if it occurs.
Question 44

Answer and see the solution →Indium is a metal that reacts slowly with hot dilute hydrochloric acid. Its position is just above hydrogen in the reactivity series.
A student adds 0.050 mol of indium to excess hydrochloric acid.
Calculate the volume of hydrogen gas formed at room temperature and pressure (RTP). (1 mol of gas occupies 24 dm³ at RTP.)
Question 45
3 marks · Normal
Answer and see the solution →A teacher places a strip of an unknown metal, labelled M, into cold water. No reaction is seen.
The teacher then adds M to cold dilute hydrochloric acid. No reaction is seen, even after warming.
Explain what these results suggest about the position of metal M in the reactivity series. Give a reason for your answer.
Question 46
4 marks · Normal
Answer and see the solution →A student investigates the reactions of five metals with dilute hydrochloric acid at room temperature.
Table 1: Observations of the reactions Metal Observation with dilute HCl Sodium Fizzes rapidly, dissolves Magnesium Slow bubbles, dissolves gradually Iron Very slow bubbles, little change Copper No reaction Calcium Bubbles rapidly, cloudy solution (a)[1 mark]Arrange the five metals in order of decreasing reactivity with dilute hydrochloric acid (most to least reactive).
(b)[1 mark]Predict whether magnesium will react with steam. Give a reason for your answer.
(c)[2 marks]Suggest, with a reason, if copper will react with silver nitrate solution.
Question 47
1 mark · Normal
Answer and check →Which metal could be used to displace nickel from nickel(II) sulfate solution?
- A.Silver
- B.Tin
- C.Iron
- D.Copper
Question 48
2 marks · Normal
Answer and see the solution →Cobalt (Co) lies between iron and copper in the reactivity series.
Predict what would happen if a strip of cobalt was placed in a solution of iron(II) sulfate. Explain your answer.
Question 49
4 marks · Normal
Answer and see the solution →Titanium is a metal that lies between aluminum and zinc in the reactivity series.
(a)[2 marks]Predict whether titanium will react with dilute sulfuric acid at room temperature. Give a reason for your answer.
(b)[2 marks]Suggest what would happen if titanium powder is heated with steam. Name a product that would be formed.
Question 50
