Sample Questions and Model Answers

The exemplar provides sample questions with detailed model answers illustrating the expected response structure:

Example 1: Multiple Choice

Question: Which of the following best describes an ionic bond?

a) Sharing of electrons between atoms

b) Transfer of electrons from one atom to another

c) Attraction between like charges

d) Formation of a metallic lattice

Answer: b) Transfer of electrons from one atom to another

Example 2: Short Answer

Question: Calculate the energy change when 2 mol of water vapor condenses at constant pressure. Given ΔH_vaporization of water = 40.7 kJ/mol.

Model Answer:

Energy change = molar enthalpy of vaporization × number of moles

= 40.7 kJ/mol × 2 mol

= 81.4 kJ (exothermic process, so energy is released)

Example 3: Extended Response

Question: Explain how the structure of a metal contributes to its ability to conduct electricity.

Model Answer:

Metals have a lattice of positive ions surrounded by a 'sea' of delocalized electrons. These free electrons can move easily throughout the lattice when an electric field is applied, allowing electric current to flow. The delocalized nature of these electrons accounts for the high electrical conductivity of metals.
