Question 111
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 112
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 113
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.
Question 114
2 marks · Hard
Answer and see the solution →Palladium (Pd) is found in the reactivity series between copper and hydrogen. Predict whether palladium will react with dilute sulfuric acid. Give a reason for your answer.
Question 115
1 mark · Easy
Answer and see the solution →State what forms on iron when it rusts.
Question 116
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.
Question 117
2 marks · Easy
Answer and see the solution →Explain why galvanising is able to protect iron from rusting even when the zinc coating is scratched.
Question 118
3 marks · Easy
Answer and see the solution →The table below shows the results of an experiment. Three identical iron nails were placed under different conditions for 10 days to investigate rusting.
Rusting of iron nails under different conditions. Test tube Conditions Rust formed after 10 days? 1 Air only No 2 Water only (boiled, air excluded) No 3 Air and water Yes (a)[1 mark]Which test tube shows the conditions needed for rusting?
(b)[2 marks]Explain why no rust formed in test tube 2.
Question 119
1 mark · Easy
Answer and see the solution →State one reason why coating iron with oil or grease helps prevent rusting.
Question 120
3 marks · Easy
Answer and see the solution →An iron bridge over a river is being considered for galvanising to prevent rusting.
(a)[1 mark]Describe the process of galvanising.
(b)[2 marks]State how galvanising protects the iron bridge from rusting.
