Sample AQA Chemistry Questions and Model Answers from 20th May Exam

1. Atomic Structure and the Periodic Table

Question:

Describe the arrangement of electrons in a potassium atom.

Answer:

Potassium has an atomic number of 19, meaning it has 19 electrons. Its electron configuration is 2, 8, 8, 1, with the first two electrons filling the first shell, the next eight filling the second shell, the following eight filling the third shell, and the remaining one in the outermost shell (valence shell). This arrangement results in a single electron in the outer shell, making potassium highly reactive.

2. Bonding and Structure

Question:

Explain why sodium chloride has a high melting point.

Answer:

Sodium chloride consists of a giant ionic lattice, where each sodium ion is electrostatically attracted to multiple chloride ions, and vice versa. These strong ionic bonds require a significant amount of energy to break. Therefore, sodium chloride has a high melting point because a lot of energy is needed to overcome these forces and change it from solid to liquid.

3. Quantitative Chemistry

Question:

Calculate the number of moles in 24 grams of carbon dioxide (CO₂).

Answer:

First, find the molar mass of CO₂:

C = 12 g/mol,

O₂ = 2 × 16 g/mol = 32 g/mol,

Total molar mass = 12 + 32 = 44 g/mol.

Number of moles = mass / molar mass = 24 g / 44 g/mol ≈ 0.545 mol.

Common Challenges and How to Tackle Them

Understanding Chemical Calculations

Many students find chemical calculations challenging, especially molar calculations, titrations, and concentration problems. To improve:

• Practice regularly with different types of calculations.
