A student was trying to extract the metals from lead oxide and aluminium oxide. 1 She heated each oxide with carbon in a fume cupboard as shown below. lumps of charcoal (carbon) mixture of powdered carbon and the metal oxide very strong heat She was able to extract lead from lead oxide but not aluminium from aluminium oxide. (1) Explain the results of these experiments.
