A student soaks mineral wool in liquid paraffin and places it at the closed end of a hard-glass boiling tube. Aluminium oxide is placed in the middle of the tube. The gases produced are collected through a delivery tube.
Name the process that occurs when paraffin vapour passes over the aluminium oxide.
State how the aluminium oxide should be heated for this process to occur.
