Question 61
2 marks · Easy
Answer and see the solution →Explain, using the reactivity series, why gold does not react with either cold water or steam.
Question 62
3 marks · Easy
Answer and see the solution →The table shows some metals and their reactions with water or steam:
Metal Reacts with cold water? Reacts with steam? Potassium Yes No Calcium Yes No Magnesium No Yes Copper No No (a)[1 mark]Identify one metal from the table that reacts only with steam but not with cold water.
(b)[1 mark]State the general word equation for the reaction of this metal with steam.
(c)[1 mark]Name the gas produced in this reaction.
Question 63
1 mark · Easy
Answer and see the solution →State one observation when calcium reacts with cold water.
Question 64
3 marks · Easy
Answer and see the solution →Zinc is heated in steam according to the equation:
(a)[2 marks]Name two products formed in this reaction.
(b)[1 mark]State the colour of zinc oxide when it has just formed (hot).
Question 65
2 marks · Easy
Answer and see the solution →Copper is used for water pipes, even for hot water. Using the reactivity series, explain why copper does not react with either cold water or steam.

(b)[1 mark]the reaction of a metal with steam.
Question 68
4 marks · Normal
Answer and see the solution →Potassium, sodium, lithium, and calcium all react with cold water, but in different ways.
(a)[2 marks]Describe two observations you would make when potassium is added to cold water.
(b)[2 marks]Explain what happens to calcium granules when they are added to cold water.
Question 69
3 marks · Normal
Answer and see the solution →Explain, using the reactivity series, why copper is suitable for use in water pipes but zinc is not.
