Chemistry 9701/13 Oct Nov 2018 | Cambridge AS Level Past Papers With Mark Scheme

The document is a set of multiple-choice questions from the Cambridge International A Level Chemistry exam, focusing on various chemistry topics such as:

1. Ionization Energies and Electron Configurations: Determining which ion is produced by removing an electron from a filled shell based on ionization energy data.
2. Gas Laws and Ideal Gases: Understanding basic assumptions of kinetic theory, applying the ideal gas law, and solving for the mass of a sample using given gas parameters.
3. Combustion and Stoichiometry: Determining the ratio of mass increases in collecting vessels during combustion and calculating the minimum mass of fuel required to heat a certain amount of water.
4. Oxidation Numbers and Redox Reactions: Identifying changes in oxidation states and writing equations for redox reactions, including the oxidation of sulfur dioxide and the reduction of transition metal ions.
5. Transition Metals and Catalysis: Exploring the behavior of transition metals as catalysts, such as in the Contact process or the role of vanadium and iron in catalyzing reactions.
6. Chromatography and Molecular Identification: Analyzing mixtures using gas chromatography and calculating percentage composition based on peak areas.
7. Coordination Chemistry: Describing the properties and behavior of metal ions and their complexes, including the splitting of d-orbitals and the effects of ligands.
8. Organic Chemistry: Identifying isomers, reaction mechanisms (such as electrophilic addition), and the properties of functional groups like alcohols, acids, and aldehydes.
9. Thermodynamics: Understanding concepts like enthalpy changes, Gibbs free energy, and entropy in various reactions and processes.
10. Polymer Chemistry: Analyzing the structures of polymers and understanding their formation and properties.
