Answer and see the solution →Name the solid products formed when:
(a)[1 mark]zinc reacts with steam,
(b)[1 mark]iron reacts with steam.
Question 32
4 marks · Normal
Answer and see the solution →Some metals do not react with water or steam.
(a)[2 marks]State whether aluminium reacts with steam and explain your answer with reference to its oxide layer.
(b)[2 marks]Explain why copper does not react with cold water or steam.
Question 33

Answer and see the solution →When 7.2 grams of magnesium ribbon are heated in steam, magnesium oxide and hydrogen gas are produced. The equation for the reaction is:
Calculate the volume (in dm) of hydrogen gas produced at room temperature and pressure (RTP) from this reaction. (Molar mass of Mg = 24 g/mol; the molar volume of a gas at RTP = 24 dm/mol)
Question 34
2 marks · Normal
Answer and see the solution →Describe two observations you could make when magnesium is added to dilute hydrochloric acid that show it is more reactive than iron.
Question 35
4 marks · Normal
Answer and see the solution →An experiment was carried out to compare the reactivity of metals with dilute hydrochloric acid. The results are:
Observations when metals react with hydrochloric acid Metal Observation Magnesium Rapid fizzing, test-tube gets hot, gas burns with a squeaky pop Zinc Steady fizzing, test-tube gets warm, gas burns with a squeaky pop Copper No reaction, no temperature change, no gas produced (a)[1 mark]Arrange the metals in order of decreasing reactivity according to the observations.
(b)[1 mark]Write a word equation for the reaction between magnesium and hydrochloric acid.
(c)[2 marks]State the name of the gas produced in these reactions and describe how it is tested.
Question 36

Answer and see the solution →Explain why it is important to use the same number of moles of metal in each experiment when comparing their reactivity with dilute hydrochloric acid.
Question 38
4 marks · Normal
Answer and see the solution →The results of an experiment measuring the temperature rise when four metals react with excess hydrochloric acid are shown in the bar chart below.
