Question

2.write a word equation for the reaction that takes place when lead oxide is heated with carbon
3.copper is less reactive than lead. explain whether carbon can be used to extract copper from copper oxide

Answer 1

Answer:

2.Carbon at first is partially oxidised to form carbon monoxide (PbO + C → Pb + CO) which then is involved in further reduction (PbO + CO → Pb + CO2).

3.Carbon is a non-metal but it is more reactive than some metals. This means that some metals can be extracted from their metal oxides using carbon. This works for zinc, iron, tin, lead and copper.
