Which statement about the extraction of metals is correct?
See it on the paper →Iron is extracted from the ore hematite by heating with carbon. Use Fig. 11.1 to state and explain how magnesium is extracted from magnesium ore.
See it on the paper →Sodium is more reactive than magnesium. Explain why.
See it on the paper →Explain why iron can be extracted from iron ore by heating with carbon.
See it on the paper →Put a tick ( ✓ ) next to the metal that cannot be extracted from its ore by heating with carbon. aluminium copper zinc
See it on the paper →Iron is extracted from iron ore in a blast furnace. Calcium carbonate (limestone) is added to the blast furnace to remove impurities in the iron ore. Complete the symbol equations to show the reactions to remove the impurities. CaCO 3 CaO + CaO + CaSiO
See it on the paper →Table 2.1 shows a reactivity series for some metals. Carbon, a non-metal, is also shown in Table 2.1. Table 2.1 sodium most reactive calcium magnesium carbon iron copper least reactive State a metal from Table 2.1 that is extracted from its ore by electrolysis. Explain your answer. metal explanation
See it on the paper →Unfortunately most candidates scored zero here. The main problem was misinterpretation of the given data, the most common response for M1 was copper. Most appeared to read the table the wrong way round, possibly thinking reactivity increased downwards. Those who did score M1 did not often score any further marks, missing the point about carbon being less reactive.
