6.Name the process by which metals can be refined : _____________

7 Write down the formula of Rust: ___________

8. Write down the difference between metallic and non metallic oxide

9. Name non metal that is good conductor of electricity : _____________​

Answer 1

Answer:

1)H2CO3

2) phosphorus

3) iron and zinc

4) metal oxides and hydrogen

5)cuso+fe

6) electrolysis

7) fe2o3

8)Metals react with oxygen to form metallic oxide while Non metals react with oxygen to form non metallic oxide.

metallic oxide are basic in nature while Non metallic oxides are acidic in nature .

metallic oxide - Na + O2 = Na2O

non metallic oxide - C + O2 = CO2

9) graphite
