NY Regents Chemistry study plan

Classify matter as element, compound, homogeneous mixture, or heterogeneous mixture from written descriptions alone

Distinguish physical changes from chemical changes and justify each classification with evidence about composition

Convert among metric prefixes and express answers in scientific notation with correct significant figures

Calculate density and use it to identify an unknown substance from a data table

Interpret a heating or cooling curve in terms of phase changes and energy absorbed or released

Write electron configurations and orbital diagrams for neutral atoms and their common ions

Locate valence electrons and predict ion charge from group number on the periodic table

Explain periodic trends in atomic radius, ionization energy, and electronegativity using nuclear charge and shielding

Describe the historical development of atomic models and the evidence that forced each revision

Differentiate isotopes and calculate weighted average atomic mass from percent abundances

Predict bond type as ionic, polar covalent, or nonpolar covalent from electronegativity differences

Draw Lewis electron-dot structures for molecules and polyatomic ions, including resonance and expanded octets where allowed

Apply VSEPR theory to assign molecular geometry and bond angles

Rank substances by intermolecular force strength and connect that ranking to boiling point and solubility

Name and write formulas for ionic and molecular compounds, including transition metals with Roman numerals

Balance skeleton equations and classify reactions as synthesis, decomposition, single replacement, double replacement, or combustion

Predict products of double replacement reactions using a solubility table and write net ionic equations

Solve stoichiometry problems converting among mass, moles, and particles for limiting-reactant scenarios

Calculate theoretical yield, actual yield, and percent yield from lab-style data

Apply conservation of mass and charge to check whether a written equation is valid

Interpret potential energy diagrams to identify activation energy, heat of reaction, and catalyst effects

Explain how concentration, temperature, surface area, pressure, and catalysts alter reaction rate in collision-theory terms

Apply Le Chatelier's principle to predict the shift caused by stress on a system at equilibrium

Write equilibrium expressions and use them to judge whether a reaction favors products or reactants

Distinguish endothermic from exothermic processes using enthalpy change and energy conservation

Calculate heat absorbed or released using q = mcΔT and interpret calorimetry data

Determine the heat of reaction from a table of heats of formation or from Hess's law reasoning

Explain entropy changes and how they combine with enthalpy to predict spontaneity

Revisit measurement and significant-figure rules as they apply to thermochemical calculations

Describe real-world applications of thermochemistry such as hand warmers or combustion fuels

Identify organic functional groups and homologous series from condensed structural formulas

Name and draw straight-chain alkanes, alkenes, and alkynes up to eight carbons, including isomers

Distinguish addition, substitution, polymerization, fermentation, and combustion reactions of organic compounds

Differentiate alpha decay, beta decay, positron emission, and gamma emission by particle emitted and change in mass number and atomic number

Complete and balance nuclear equations and determine half-life or remaining mass after a given number of half-lives

Assemble a cumulative error log from weeks 1 through 7 and re-solve every missed problem

Complete two full-length timed practice exams under Regents conditions and score them using the reference tables

Drill reference-table fluency by locating constants, solubility rules, and periodic data within 30 seconds each

Write and explain the 15 most frequently tested relationships across all six domains

Build a final-week review sheet limited to items still missed on the second practice exam
