Question 81
3 marks · Easy
Answer and see the solution →Copper is a metal and sulfur is a non-metal. Using their physical properties, answer the following:
(a)[1 mark]State the typical appearance (shiny/dull) of copper and sulfur.
(b)[1 mark]Describe whether copper and sulfur are likely to be malleable or brittle.
(c)[1 mark]Give one property of copper that makes it suitable for use in electrical wiring.
Question 82
2 marks · Easy
Answer and see the solution →The length of a copper wire needed to connect two points is 5 metres. If a non-metal such as sulfur was used to try to make a wire of the same length for carrying an electric current, would it work? Explain your answer using a physical property of metals and non-metals.
Question 83
2 marks · Easy
Answer and see the solution →When 0.1 mol of sodium oxide (a metal oxide) is dissolved in water, it produces sodium hydroxide solution, which is alkaline. When 0.1 mol of sulfur dioxide (a non-metal oxide) is dissolved in water, it forms an acidic solution. Calculate the total number of moles of hydroxide ions, OH⁻, produced from the sodium oxide, and the total number of moles of hydrogen ions, H⁺, produced from the sulfur dioxide, after complete reaction in water. State which oxide forms a solution with pH greater than 7, explaining your answer.
Question 84
2 marks · Normal
Answer and see the solution →State one example of a metal and one example of a non-metal. For each, identify whether it conducts electricity or not.
Question 85
4 marks · Normal
Answer and see the solution →(a)[2 marks]State what is meant by a basic oxide and give one example of a basic oxide formed by a metal.
(b)[2 marks]Explain, using a chemical equation, how an acidic oxide formed by a non-metal reacts with an alkali.
Question 86
3 marks · Normal
Answer and see the solution →Titanium is a metal with a melting point of about 1670°C, and sulfur is a non-metal with a melting point of about 115°C. Calculate the difference in melting points between titanium and sulfur. Give your answer and then, using this data, explain one difference in the physical properties of metals and non-metals.
Question 87
3 marks · Normal
Answer and see the solution →Graphite is a form of carbon, a non-metal. Unlike most non-metals, graphite conducts electricity. Explain why graphite is an exception among non-metals in terms of electrical conductivity.
Question 88
4 marks · Normal
Answer and see the solution →Some metal and non-metal oxides and their reactions Oxide Type Reacts with acid? Reacts with alkali? CuO Metal Yes No SO2 Non-metal No Yes Al2O3 Metal Yes Yes CO Non-metal No No (a)[1 mark]Identify one oxide in the table that is amphoteric.
(b)[1 mark]Give a reason for your answer to (a).
(c)[1 mark]State which oxide in the table is neutral.
(d)[1 mark]Name one oxide that reacts with alkalis to form salts.
Question 89
1 mark · Normal
Answer and check →Which of the following is a common physical property of most non-metals?
- A.They are shiny when polished.
- B.They are malleable.
- C.They are brittle when solid.
- D.They conduct electricity well.
Question 90
2 marks · Normal
Answer and see the solution →State one exception to the general rule that metals are solid at room temperature, and one exception to the rule that non-metals do not conduct electricity.
