Regents Physical Setting/Chemistry (NYSED): complete guide to the exam, the four parts, the Reference Tables and the lab requirement

A complete guide to the New York State Regents Examination in Physical Setting/Chemistry. Covers the four-part exam (Parts A, B-1, B-2 and C), the 2011 Reference Tables you are given, the 1,200-minute lab requirement, and how to study every core topic from atomic structure to nuclear chemistry.

The New York State Regents Examination in Physical Setting/Chemistry is the statewide end-of-course exam for high-school chemistry. It is built directly from the Physical Setting/Chemistry Core Curriculum, it is three hours long, and it is worth 100 raw-score points across four parts. Two things make it distinctive: you sit it with the Reference Tables for Physical Setting/Chemistry in hand, and you must have completed a 1,200-minute laboratory requirement before you are admitted. This page is the index for our Regents Chemistry library: below is the exam format, the role of the Reference Tables, the lab requirement, and how to study each core topic.

The four parts of the exam

The exam has four parts. Parts A and B-1 are multiple choice on a single answer sheet; Parts B-2 and C are constructed response written in a separate answer booklet.

Part A (30 questions, multiple choice)
Broad, stand-alone questions across every core topic, from atomic structure to nuclear chemistry. These reward quick recall and confident use of the Reference Tables.
Part B-1 (about 20 questions, multiple choice)
More data-driven items, often tied to a graph, diagram, table or short passage, but still answered by choosing one option. Parts A and B-1 together give 50 multiple-choice questions.
Part B-2 (short constructed response)
Numeric answers with units, short written explanations, completing or balancing equations, drawing Lewis (electron-dot) diagrams, and labelling diagrams. Quantitative work (moles, gas laws, heat, pH, half-life) features heavily, and you must show your working.
Part C (extended constructed response)
Longer, multi-step tasks that often combine several topics and lean on laboratory skills: titration data, calorimetry, particle diagrams, equilibrium shifts, redox and nuclear decay. Part C is where evidence-based reasoning and careful use of the Reference Tables earn the most points.

The Reference Tables

Every candidate is given the 2011 Edition Reference Tables, and the exam is written on the assumption that you will use them. They are not just a formula sheet: they are data, constants, classification charts, graphs and equations. The key tables are:

  • Table A Standard temperature and pressure (STP).
  • Table B Physical constants for water (specific heat, heat of fusion, heat of vaporization).
  • Table C and Table D Selected prefixes and units.
  • Table E Selected polyatomic ions (names, formulas, charges).
  • Table F Solubility guidelines (which ionic compounds are soluble).
  • Table G Solubility curves (grams of solute per 100 g water against temperature).
  • Table H Vapor pressure of four liquids against temperature.
  • Table I Heats of reaction at 101.3 kPa and 298 K.
  • Table J Activity series of metals and hydrogen.
  • Table K and Table L Common acids and common bases.
  • Table M Common organic substances.
  • Table N Selected standard reduction potentials.
  • Table O Symbols used in nuclear chemistry.
  • Table P Organic prefixes (meth-, eth-, prop- and so on).
  • Table Q Homologous series of hydrocarbons.
  • Table R Organic functional groups.
  • Table S Properties of selected elements (atomic number, mass, electronegativity, first ionization energy).
  • Table T Important formulas and equations (density, mole calculations, percent composition, percent error, the combined gas law, the heat equations q=mCΔTq = mC\Delta T and q=mHfq = mH_f, titration, and the half-life relationship).

Throughout our dot-point pages we tell you exactly which table a question expects you to open.

The laboratory requirement

New York State requires a minimum of 1,200 minutes (20 hours) of hands-on laboratory experience, with satisfactory written reports, before a student may sit a Physical Setting science Regents exam. This is a state rule, certified by your school, not a local option. The skills it builds are tested directly: measuring mass, volume and temperature; reading a meniscus and a buret; plotting and reading graphs (heating curves, solubility curves); performing titration and calorimetry; using the activity series and solubility guidelines to predict reactions; and identifying and reducing sources of experimental error.

How to study Regents Chemistry

  1. Learn the Reference Tables actively. Practice locating Table G, Table H, Table N, Table S and Table T fast. A large share of marks is simply reading the right value.
  2. Show your working on constructed response. Part B-2 and Part C award points for the setup and the units, not only the final number. Carry extra digits and round at the end.
  3. Reason at the particle level. Many questions ask you to explain a macroscopic property (boiling point, conductivity, polarity) from particles and bonding.
  4. Keep the math tidy. Regents calculations are one- or two-step algebra. Identify the formula on Table T, substitute with units, and solve.
  5. Rehearse the command words. "State", "Determine", "Explain", "Calculate" and "Compare" each expect a specific shape of answer.

Common questions about Chemistry

How is the Regents Physical Setting/Chemistry exam structured?
The exam is three hours and has four parts worth 100 raw-score points. Part A is 30 multiple-choice questions on the core material. Part B-1 is about 20 multiple-choice questions, usually built on data, diagrams and graphs. Part B-2 is short constructed-response questions (numeric answers with units, short explanations, labelled diagrams). Part C is longer constructed-response tasks that combine topics and lab skills. Parts A and B-1 together are 50 multiple-choice questions on one answer sheet; Parts B-2 and C are written in a separate answer booklet.
What are the Reference Tables for Physical Setting/Chemistry?
Every student is given the NYSED Reference Tables (2011 Edition), a booklet of data, constants, graphs and formulas. They run from Table A (standard temperature and pressure) through Table S (properties of selected elements) plus Table T (important formulas and equations) and a periodic table. Many questions are written so you must look up a value or read a graph (for example a Table G solubility curve, a Table H vapor-pressure curve, or a Table T heat formula). You are not expected to memorize constants; you are expected to find and use them.
What is the laboratory requirement for the Chemistry Regents?
New York State requires a minimum of 1,200 minutes (20 hours) of hands-on laboratory experience with satisfactory written lab reports before a student may sit a Physical Setting science Regents exam. Your school certifies that you have met this requirement. Part B-2 and Part C questions are frequently modelled on lab work: reading a buret, interpreting a heating curve, identifying sources of error, or improving a procedure.
How is the Chemistry Regents scored and what is a passing mark?
The 100 raw-score points are converted to a scaled score of 0 to 100 using the conversion chart published with each exam. A scaled score of 65 is the passing (Regents) standard. Because the raw-to-scale conversion is not one-to-one, you should always check the official conversion chart for the specific administration rather than assuming 65 raw equals a pass.
What core topics does the Regents Chemistry exam cover?
The exam is built from the Physical Setting/Chemistry Core Curriculum. The major areas are atomic concepts, the periodic table, chemical bonding, the mole concept and stoichiometry, the physical behavior of matter (gases, phases, energy and solutions), kinetics and equilibrium, acids, bases and salts, oxidation-reduction and electrochemistry, organic chemistry, and nuclear chemistry. The math stays at algebra level and the Reference Tables supply the data.
How does the Regents Chemistry exam differ from honors or AP Chemistry?
The Regents exam tests a Bohr-model, particle-level view with single- or two-step algebra and no calculus. Topics that are honors or AP only, such as the solubility product Ksp, full Gibbs free-energy calculations and orbital notation with Hund's rule, do not appear on the standard Regents exam. Reasoning is qualitative for many topics (for example Le Chatelier shifts and polarity), and the Reference Tables are used actively throughout.
What's the difference between ionic and covalent bonding?
Ionic: electrons are transferred between atoms (typically metal + non-metal); forms a lattice. Covalent: electrons are shared (non-metal + non-metal); forms discrete molecules or networks.
How do I calculate pH?
pH = -log₁₀[H⁺]. For strong acids/bases, [H⁺] equals the concentration. For weak acids, use Ka. For buffers, use Henderson-Hasselbalch.
What's Le Chatelier's principle?
When a system at equilibrium is disturbed (concentration, temperature, pressure change), the equilibrium shifts to partially counteract the disturbance.
How do I balance a redox equation?
Identify the half-reactions (oxidation and reduction), balance atoms (excluding O and H), balance O with H₂O and H with H⁺, balance charge with electrons, then combine so electrons cancel.
What's the difference between enthalpy and entropy?
Enthalpy (ΔH) is the heat change of a reaction. Entropy (ΔS) is the change in disorder. Gibbs free energy (ΔG = ΔH - TΔS) tells you if the reaction is spontaneous.
