The official HSC Chemistry formula sheet and data sheet are supplied together in one NESA file. It also includes the periodic table. Use the file below while you practise calculations, analyse chemical data and work with the periodic table. Your job is to find the information you need and use it without mixing up symbols, units or conditions.

Which students and exams does this resource apply to?
NESA identifies this resource as the Chemistry formulae sheet, data sheet and periodic table for HSC examinations from 2019. It belongs with the Chemistry Stage 6 Syllabus (2017). Students preparing for a later syllabus should check the current NESA Chemistry page, because the supplied reference material may change when a new course reaches the HSC examination.
What is included?
The sheet combines common chemical formulae, constants, standard electrode potentials, solubility information, indicators, spectroscopy data and a periodic table. It is a reference, not a worked-answer guide. You still need to select a suitable relationship, balance equations, handle significant figures and explain the chemistry shown by the result.
How to use the HSC Chemistry formula and data sheet
Make the sheet part of regular question practice. Begin by naming the chemical model, the quantities supplied and the result required. Then locate the formula, constant or table entry. This order exposes weak chemistry reasoning instead of hiding it behind a successful search.
The unfiltered bottom line
- The sheet can’t identify the reaction. Decide which chemical model and quantities apply before choosing a formula or data value.
- Units and conditions change answers. Check concentration, volume, temperature, pressure and required conversions before substitution.
- A periodic-table value needs a purpose. State what the value represents and connect it to the calculation or explanation being assessed.
Learn where each kind of data sits
Use a clean copy during topic questions and note which section you reach for. Practise locating acid-base data, redox information, constants and spectroscopy values before you begin a calculation. Familiarity with the layout leaves more time to interpret the question.
Write the units before substituting
Copy each value with its unit and convert it before using a formula. Check if concentration, volume, energy and pressure are expressed in compatible forms. A correct formula with mismatched units can still produce a convincing but wrong number.
Pair the sheet with written explanations
After a calculation, ask what the value means chemically. Practise writing one sentence that links the result to equilibrium, reaction direction, structure or another idea in the question. The sheet supplies data, but the marks often depend on the explanation you build from it.
Common mistakes to watch for
- Treating the periodic table value as an exact mass for every isotope.
- Selecting a formula because the symbols look familiar without checking the conditions.
- Rounding during an early step and carrying the error through the calculation.
- Quoting a data value without explaining how it supports the answer.
A reliable Chemistry check: Keep the same official sheet beside you from your first topic questions through to full timed papers. By exam day, finding the data should feel ordinary, so your attention can stay on the chemistry and the wording of the question.
What they say about our tutoring
Mitchell is happy with the new tutor, thank you. Sean is a good communicator which makes Mitchell feel more relaxed thanks again.
We are very happy with Sheetal. Timothy is making great progress and we are happy to continue. We will have Tim do his Navy test in a few weeks and if we need to do a bridging course we will ask Sheetal to tutor him with that as well.
