Question

reactive metals are good reducing agents the most suitable example related to this
1)Pbo + C ---- Pb+CO
2)3MnO2+4AL ---- 2Al2O3+Mn
3)ZnO + C ---- Zn+Co
4)CuO+H2 ----Cu+H20​

Answer 1

Answer:

2nd one option is the correct answer..

Answer 2

Option 2 is the most suitable example that shows that reactive metals are good reducing agents.

• Aluminium is a reactive metal.
• Reactive metals generally have tendency to lose electrons and convert itself into a cation.
• Since reactive metals lose electrons easily and themselves gets oxidized  they act as good reducing agents.
• Here Al is losing electron to produce Al(III) ion which combines with oxygen to form Aluminium oxide.
• Aluminium is itself being oxidized so it will reduce MnO2 , hence acting as a good reducing agent.
