Answer 1

6. If Na is kept open in air, it form Na2O. If K is kept opened in air, it forms KO2.
7. Mg > Fe > Cu
8. Some natural acids are corrosive and they react with metals to form salts          and H2 gas. So, foods containing acids should not be stored in metallic              containers.
9. Zn + CuSO4 = ZnSO4 + Cu
10. A reaction in which a more reactive metal displaces a less reactive metal        from its salt is called displacement reaction. Example: (Ans No. 9)
11. Some metals are more reactive than other metals. So, they displace the          less reactive metals.
12. Metals are malleable (except Na, K, Ca) but non-metals are not malleable.
Metals are ductile (except Na, K, Ca) but non-metals are not ductile.
Metals are good conductors of heat and electricity but non metals are bad conductors of heat and electricity (except Graphite).

Hope this helps :)
