Question 101
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 102
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 103
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 104
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 105
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 106
3 marks · Normal
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 107
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 108
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 109
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 110
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.
