i considering the following experiment, answer the qu-
estions given below it:
Take lo ml ethanol in a big test tube. cut sodium metal
mto 2-3 pieces of a gerial goaun size. put the Sodium
pieces into the ethanol in the test tube & fix the gas
delivery tube to the tube test. Take a buoning candie
near the outlet of the gas delivery tube & observe.
c) repeat the above procedure using magnesium ribbon instead of a sodium​
