What SEAB actually provides (Chemistry Data Booklet)
What you still need to memorise (or derive quickly)
Q: Is there an H2 Chemistry formula sheet for A Levels (9476)? A: SEAB provides a Chemistry data booklet for the written papers, but it is not a full formula sheet. Use this page to separate the equations SEAB gives you from the ones you still need to memorise and rearrange quickly.
TL;DR SEAB gives a Chemistry Data Booklet, not a complete formula sheet. Use it for constants, tables, and reference data, but memorise the equations that set up the question.

The booklet gives data, not method.
Do not wait for a formula list to solve the question.
Convert cm3 to dm3 or m3 before using the chosen equation.
Concrete example: The data booklet may give R, but you still need to know when to set up PV=nRT, which units match that value of R, and how to rearrange for n.
If you searched “H2 chem formula sheet” or “H2 Chemistry formula list”, what you are usually looking for is two different things:
What SEAB gives you on exam day: the official Chemistry Data Booklet (tables, constants, reference ranges).
What you must still carry in your head: core equations and standard relationships that let you turn the question into steps.
This post clarifies the boundary so you stop over-memorising tables, but also don’t get surprised by missing formulas.

What SEAB actually provides (Chemistry Data Booklet)
SEAB supplies the official Chemistry Data Booklet for the written papers (see the cover page of the SEAB PDF). It typically includes:
What you still need to memorise (or derive quickly)
The data booklet is not designed to replace understanding. You should still memorise or be fluent with:
Core “setup” equations (high-frequency)
Mole relationships: n=Mm, n=NAN (SEAB’s data booklet lists the Avogadro constant as L).
Concentration: c=Vn (and unit conversions for dm3 vs cm3
Ideal gas: PV=nRT (choose R units that match P and V).
Electrochemistry “must-knows”
Cell potential: Ecell∘=Ecathode∘−Eanode∘.
Optional enrichment (not required explicitly by the 9476 syllabus):
Nernst (base-10 form at 298K): E=E∘−n0.0592log10Q. Use this only if your class/notes cover it or if the exam question provides the relationship; otherwise, focus on Ecell∘ and qualitative concentration effects.
Energetics “must-knows”
Calorimetry sign conventions and relationships (e.g., q=mcΔT, ΔH=−nq where appropriate).
Hess law logic (build a cycle cleanly; identify what is “given” vs “asked”).
Acid-base and equilibria “must-knows”
Definitions of Kc, Kp, Ka, Kb (and the direction they describe).
Henderson–Hasselbalch form when a buffer approximation is valid: \text{pH} = \text{p}K_{a} + \log_{10}\dfrac{[\text{A^-}]}{[\text{HA}]}.
How this affects your Paper 1–3 preparation
Treat the data booklet as a speed tool, not a memory crutch: you should know where to find values and what to do with them.
Is the H2 Chemistry “formula sheet” the same as the data booklet?
No. The data booklet is a reference booklet (tables/constants/reference ranges). Many formulas and relationships are not provided as a “sheet”, so you still need to memorise the high-frequency equations and be comfortable rearranging them.
Can I bring my own formula sheet into the A-Level exam?
No-SEAB provides a clean booklet for the written papers. Train under exam conditions by practising with an unmarked copy of the official data booklet and relying on memorised/derived formulas in your working.
What should I memorise first if I’m short on time?
Start with the setup equations n=Mm, c=Vn, and PV=nRT, then add the electrochem and buffer/equilibria relationships you use most often in Paper 2 and Paper 3.
