Across
- 3. The sum of oxidation states of all the atoms present in the formula of a compound is
- 4. The oxidation number of this chemical element in all compound is always -2 except in fluorine compounds and in peroxides which is -1
- 5. The electrode placed in a solution containing a reducing agent acts as the
- 6. A reaction in which one element displaces another element from its salt solution
- 9. The oxidation number of this chemical element in all compound is +1 except in metal hydrides
- 13. Redox reaction between iron, oxygen and water to form a brown substance (rust) is called
- 14. The oxidation number of this chemical element in all compound is always -1 because it is the most electronegative element
- 16. Daniell cell is one of the example of

- 11. The reactant that accepts electrons acts as a
- 12. Loss of hydrogen and gain oxygen
- 15. One of the example of unreactive metals that do not corrode because they are resistant to oxidation
