What are the topics covered in the provided image?

The image contains a series of "EXAMINATION TICKET" (ЭКЗАМЕНАЦИОННЫЙ БИЛЕТ) questions, numbered from 6 to 12. The topics covered are primarily related to chemistry, specifically:

• Ticket № 6: Halogens (occurrence, properties, compounds, preparation, uses) and experimental confirmation of qualitative composition of inorganic substances (sulfuric acid).
• Ticket № 7: Theory of electrolytic dissociation (basic principles, formulation, essence) and calculation of mass yield percentage.
• Ticket № 8: Acids (concept, properties, significance in the context of electrolytic dissociation theory), writing ionic equations, and demonstrating genetic relationships between inorganic substances of different classes through a chain of transformations.
• Ticket № 9: Bases (concept, properties, significance in the context of electrolytic dissociation theory), writing ionic equations, and calculation of initial substance mass given yield and theoretical yield percentage.
• Ticket № 10: Salts (concept, properties, significance in the context of electrolytic dissociation theory), writing ionic equations, and completing equations in full, ionic, and net ionic forms.
• Ticket № 11: Oxides (concept, properties, significance in the context of electrolytic dissociation theory), writing ionic equations, and writing hydrolysis equations for salts formed from strong bases/weak acids and strong acids/weak bases.
• Ticket № 12: Classification of chemical reactions (by reactants/products, oxidation states, thermal effect, catalyst, phase state, etc.) with examples, and calculation of the thermal effect of a reaction given the amount of one reactant and the heat released/absorbed.
