Practise for the national exam the way it really feels. This paper follows the structure, question types, marks and timing of the NESA Senior 6 (A-Level) Chemistry exam.
These questions simulate the national exam. They are original Ganzaa questions written in the same format as the NESA papers — not the official NESA papers, and not endorsed by NESA. The official papers stay free on our past papers page.
10 versions of every question, so each attempt is a fresh paper with the same structure.
180 minutes, 100 marks, the same sections and question types as the national exam.
Your score, the correct answer to every question and a clear explanation of why.
Section A
Attempt all questions. (70 marks)
Section B
Attempt any THREE questions. (30 marks)
Answer any 3 of 5
A taste of the paper. Every exam you sit has different questions in this style.
Sample 1 · Atomic structure
Give the term that corresponds to each of the following definitions or statements.
Atoms of one element that have the same proton number but different nucleon (mass) numbers.
Answer: isotopes
Isotopes have the same number of protons (same element) but different numbers of neutrons, e.g. and .
Sample 2 · Group 14 elements
State whether each of the following statements is True or False.
In graphite, each carbon atom is covalently bonded to three other carbon atoms in flat hexagonal layers.
Answer: True
True. Graphite is made of layers of hexagonal rings; each C uses three electrons in bonds and the fourth is delocalised.
Sample 3 · Acid–base theories
Choose the best answer among the alternatives given.
According to the Brønsted–Lowry theory, a base is:
Answer: C. a proton acceptor.
A Brønsted–Lowry base accepts a proton (); an acid donates one. Electron-pair acceptor is the Lewis definition of an acid.
