Question 361
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 362
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 363
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 364
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 365
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 366
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 367
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 368
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 369
2 marks · Hard
Answer and see the solution →Thallium (Tl) is a metal that is just below lead in the reactivity series. Predict whether thallium will react with dilute hydrochloric acid at room temperature. Explain your reasoning.
Question 370
5 marks · Hard
Answer and see the solution →A new metal, X, is known to react slowly with dilute sulfuric acid at room temperature, but shows no reaction with cold water. X is placed between magnesium and iron in the reactivity series.
(a)[2 marks]Predict whether metal X will react with steam. Explain your answer.
(b)[3 marks]X is added to a solution of copper(II) sulfate. Predict what will happen. Write a chemical equation for any reaction.
