Question

)arrange the metal al, cu, fe, pb, mg, zn and na in descending order of their reactivity towards oxygen.​

Answer 1

na , mg , al , Zn , fe , pb , cu

Answer 2

Na, Mg, Al, Zn, Fe, Pb, Cu.

Explanation:

• The metal reacts with the oxygen and form the metal oxide. The formation of the metal oxide is the redox reaction.
• The metal which is more reactive towards the 'metal' is more vigorously burns in the oxygen.
• So according the reaction with oxygen the metal can be arranged in the descending order- 'Na, Mg, Al, Zn, Fe, Pb, Cu'. This arrangement is done on the basis of the vigorously burn the metal with the oxygen.
