1. Calculation of the first ionisation energy of oxygen, including state symbols and trend analysis across Period 2.
2. Explanation of deviations in the ionisation energy trend for specific elements, including electronic configurations.
3. Identification of the electronic configuration of element E based on ionisation energy data.
4. Understanding and identifying the types of bonding in Period 3 oxides and their reactions with water.
5. Calculation of enthalpy changes and understanding reaction mechanisms, such as in the oxidation of SO2 and its catalytic behavior with NO2.
6. Reaction mechanisms of hydrogen halides with organic compounds and the effect of solvents on the reaction products.
7. Analysis of qualitative reactions for the identification of compounds, including the observation of physical and chemical changes.
