Here are four tips to help you get the score you need. If you’re taking the Chemistry Regents test to fulfill high school graduation requirements, it’s very important that you pass the test. Voltaic reactions produce electrical energy. Question 2: Explain, in terms of electrical energy, how electrolysis reactions differ from voltaic reactions.Īnswer: Electrolysis reactions use electrical energy. The salt bridge causes ions to flow from place to place. Question 1: State the purpose of the salt bridge in the cell.Īnswer: The salt bridge is used for ion migration. On parts 2 and 3 of the Chemistry Regents, you’ll have to short answer questions that follow an image or diagram. The answer is A: Protons and electrons are found in the nucleus of an argon atom.Ĭhemistry Regents Constructed Response Sample Question Which particles are found in the nucleus of an argon atom? Parts 1 and 2 of the Chemistry Regents have multiple-choice questions from all units that you cover during the school year. In this section, we’ll give Chemistry Regents review questions so you can see what the content on the test is like.Ĭhemistry Regents Multiple-Choice Sample Questions One of the best ways to prepare for a test like the Chemistry Regents is to practice. You’ll also receive a copy of the periodic table of elements.Ĭhemistry Regents Review: Sample Questions Table T: Important Formulas and Equations.Table S: Properties of Selected Elements.Table Q: Homologous Series of Hydrocarbons.Table O: Symbols Used in Nuclear Chemistry.Table I: Heats of Reaction at 101.3 kPa and 298 K.Table H: Vapor Pressure of Four Liquids.Table G: Solubility Curves at Standard Pressure.Table F: Solubility Guidelines for Aqueous Solutions.Table C: Selected Prefixes (e.g., kilo-, centi-).Table A: Standard Temperature and Pressure.As part of the exam, you’ll receive 20 Chemistry Regents reference tables that you will use on the test. You’ll also need to demonstrate your abilities at graphing, solving equations, and consulting reference tables. There are twelve specific topic areas covered on the Chemistry Regents exam. For these questions, you may have to perform tasks like writing responses, drawing graphs or diagrams, or using equations and the Chemistry Regents Reference tables. Part C has approximately 15 short answer questions that are broken down into smaller parts. The questions focus on the provided Chemistry Regents Reference Tables (more on these tables in a bit), graphing, and laboratory experiments. Part B has 25 questions that are a mix of multiple choice and short answer. Part A has 35 multiple choice questions from all units that you cover during the school year. The Chemistry Regents Exam has three sections: You’ll need to pass at least one of these four exams to graduate high school. The other three are Earth Science, Living Environment, and Physics. The Chemistry Regents is one of the four science Regents exams. In order to graduate from high school in New York state, you’ll need to pass five Regents exams: English Language Arts, a math, a science, a social studies, and any additional Regents exam or another option approved by the State. The Regents exams measure your achievement in school. The next Chemistry Regents exam is in January 2020. The NY State High School Regents exams are given three times a year: January, June, and August. In the guide, I’ll cover the format of the chemistry regents, list the concepts you can expect to see on the test, and provide sample questions for your chemistry regents review. The number of electrons in the outermost shell of each atom is the same.Confused about how to begin studying for the chemistry regents? This review guide will help you learn what’s on the test and how to prepare for it. In the ground state, an atom of each element has two valence electrons. "in terms of atomic structure" so same group is now a wrong answer Use the Periodic Table and analyze the electron configuration on the bottom (Sr = 2-8-18-8-2 and Mg =2-8-2)Ī strontium atom in the ground state has two more electron shells than a magnesium atom in the ground state.ĥ6 Explain, in terms of atomic structure, why the elements in Group 2 have similar chemical properties. Īs atomic number increases, first ionization energy decreases.ĥ5 State, in terms of the number of electron shells, why the radius of a strontium atom in the ground state is larger than the radius of a magnesium atom in the ground state. Base your answers to questions 54 through 56 on the elements in Group 2 on the Periodic Table.ĥ4 State the general trend in first ionization energy for the elements in Group 2 as these elements are considered in order from top to bottom in the group.
