COMPREHENSIVE SCRIPT 2026 QUESTIONS
AND ANSWERS GUARANTEED TO PASS
◉ What is the purpose of the AQA website in relation to the mark
scheme? Answer: To provide access to copies of the mark scheme
and other resources for registered schools and colleges.
◉ What does 'typical answer or answers' mean? Answer: It refers to
the responses that are expected from students and that would
typically receive full credit.
◉ What is the importance of clarity in marking instructions?
Answer: To ensure that examiners understand how to apply the
mark scheme consistently and accurately.
◉ What does 'legislated for' mean in the context of alternative
answers? Answer: It means that any alternative answers discussed
during standardisation are formally included in the mark scheme.
◉ What is the significance of the assessment objectives? Answer:
They outline the specific skills and knowledge that the exam is
designed to assess.
,◉ What does 'neutral responses' mean? Answer: Responses that do
not contribute to either gaining or losing marks, often indicated by a
specific notation.
◉ What is the shape of fullerenes? Answer: Spherical or ball-shaped.
◉ What are some applications of fullerenes? Answer: Drug delivery,
hydrogen storage, anti-oxidants, reduction of bacterial growth,
catalysts, strengthening materials, and lubricants.
◉ What is the molecular formula for acetone? Answer: C3H6O or
CH3COCH3.
◉ What can be said about the intermolecular forces in certain
substances? Answer: The intermolecular forces are weak.
◉ What is the structure of graphite? Answer: Graphite has a layered
structure of interlocking hexagonal rings with weak intermolecular
forces between layers.
◉ What is the reason graphite conducts electricity? Answer:
Graphite has delocalised electrons that can move through the
structure, carrying electrical charge.
, ◉ What happens to the layers of graphite? Answer: The layers can
slide over each other, making graphite soft and slippery.
◉ What defines isotopes? Answer: Atoms with the same number of
protons but different numbers of neutrons.
◉ How is the relative atomic mass calculated? Answer: By taking the
weighted average of the masses of an element's isotopes.
◉ What is the electron configuration for gallium? Answer: Gallium
has 31 electrons.
◉ What is the charge of a gallium ion? Answer: Ga3+.
◉ What is the significance of Mendeleev's periodic table? Answer:
Gallium fitted in a gap that Mendeleev had left, and its properties
were predicted correctly.
◉ What is the molar mass of water? Answer: The molar mass of
water (H2O) is 18 g/mol.
◉ What is the formula for the reaction of potassium with water?
Answer: 2 K + 2 H2O → 2 KOH + H2.
