Chem Pongal Tasks

10 points per sheet

STD 9 and STD 10 Tasks

1. Elements, cations, anions and Symbols – 2 sheets = 20points
2. Chemical name and molecular formula – 2 sheets = 20points
3. Determination of oxidation number of elements in a molecule -2 sheets = 20points
4. Balancing of Chemical Reactions by the following methods
   a) ERP – 2 reactions in 2 sheets = 20points
   b) Oxidation number – 2 reactions in 2 sheets = 20points
   

STD 12 Tasks

Balancing of Chemical Reactions by the following methods
1. Oxidation number – 2 reactions in 2 sheets = 20points
2. Ion electron method in acid and base – 4 reactions in 4 sheets( 2 – acidic medium , 2 – basic medium) = 40points
3. Algebraic method – 2 reactions in 2 sheets = 20points
4. Matrix method – 2 reactions in 2 sheets = 20points
