31–40 of 43 · Easy
Question 31
2 marks · Easy
Answer and see the solution →An oxide of aluminium (Al) reacts with hydrochloric acid to produce 27 grams of aluminium chloride. Given the information below, use the periodic table and your knowledge of metals and oxides to calculate the number of moles of aluminium chloride formed. (Al = 27, Cl = 35.5)
Question 32
1 mark · Easy
Answer and see the solution →State whether most metals are malleable or brittle.
Question 33
3 marks · Easy
Answer and see the solution →The table lists four elements: sodium, aluminium, sulfur and silicon.
(a)[2 marks]State whether each of these elements conducts electricity or not (at room temperature).
(b)[1 mark]Name one exception among non-metals that conducts electricity.
Question 34
2 marks · Easy
Answer and see the solution →Diamond is a form of carbon, a non-metal, but it is the best conductor of heat of all the elements. Explain why diamond is still considered a non-metal despite this property.
Question 35
3 marks · Easy
Answer and see the solution →The following table shows whether certain elements conduct electricity at room temperature:
Element Conducts electricity? Magnesium Yes Bromine No Lead Yes Iodine No (a)[1 mark]Identify which two elements in the table are non-metals.
(b)[1 mark]State what the data shows about the electrical conductivity of metals compared to non-metals.
(c)[1 mark]Give one reason why electrical wires are not made from non-metals.
Question 36
1 mark · Easy
Answer and see the solution →State whether the oxide of carbon is acidic, basic, or amphoteric.
Question 37
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 38
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 39
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 40
5 marks · Easy
Answer and see the solution →This question is about the arrangement of electrons in atoms and representing them with diagrams.
(a)[2 marks]State what the vertical columns and horizontal rows in the Periodic Table are called.
(b)[1 mark]Phosphorus has atomic number 15. Write its electronic configuration using numbers separated by commas.
(c)[2 marks]Draw a diagram to show the arrangement of electrons in a phosphorus atom. Use circles for shells and crosses (×) for electrons.
