Before completing this worksheet, chemists are supposed read a portion of their textbook. Assign the chapter on bond energies, endothermic, and exothermic reactions. Then have your class answer the questions and fill in the data tables on this neatly formatted handout.
The chart that is required to answer the first question is printed on another worksheet by the same author. You could have learners find an average bond energies table in their textbooks or online if you want to use this otherwise terrific worksheet. It asks your high school chemists to calculate heat, entropy, and free energy changes for different chemical reactions.
The National Chemistry Olympiad exams are comprehensive tests covering an entire year of chemistry concepts. You can use them as practice for competing in the challenge, or simply as a review, or as an actual final exam for your general chemistry class. This particular part of the three-part exam consists of 60 multiple choice questions. Read through it before assigning to make sure every question is relevant to your curriculum. As a bonus, you will find an answer key attached.
The 2009 version of the first part of a national chemistry competition is posted for your use with olympiad hopefuls. Test takers deal with 60 multiple choice questions covering an entire year of chemistry curriculum. Use this to practice for the competition or to prepare for a final exam on behavior of gases, properties of metals, chemical reacitons, pH and titration curves, ionizaton energy, molecular geometry, and more!
For advanced chemists, this instructional activity examines heat change during chemcial reactions. Alkanes are examined first. Learners calculate the energy released or needed during a reaction.
This is a review of how advanced chemistry learners handle thermodynamics equations and calculations. Charts and graphs are included for them to read in addition to solving related problems. You will find this resource useful as a review homework or preparation for a unit quiz.
Sixty multiple-choice questions test on a variety of first year chemistry subjects. In order to succeed, exam takers must be competent with properties of elements, stoichiometry problems, gas laws, bond dissociation, and types of reactions. A page is provided that displays a comprehensive chart of abbreviations and symbols, constants, and the periodic table. Also, an answer key is provided for teachers. This is a top-notch exam!
In this AP Chemistry worksheet, learners apply concepts of electron configuration to accurately answer the questions provided. Students also draw Lewis structures of the given elements. Learners estimate the enthalpy of formation as well as enthalpy of sublimation.
In this reaction mechanisms worksheet, students are given examples of various reactions that occur in organic chemistry. These examples include electrophilic substitution, nucleophilic substitution, elimination reactions, displacement reactions and free radical substitution.
All you will find in this resource is a list of vocabulary terms dealing with chemical bonds. Space is provided for chemistry learners to write out definitions. This would be a terrific tool to help prepare them for a quiz.
In this chemistry unit worksheet, students study the energy involved in chemical reactions. They solve 7 exercise sections on chemical equations.
Two versions of this handout are provided, the second with more detailed information on the same topics. Chemistry aces survey chemical reactions, heat energy transferred, and the action of enzymes by reading this resource. You can either give it to learners as a study guide, or keep it for your own use as a lecture guide. Either way, you will find it to be organized and applicable for a general chemistry course.
Advanced chemistry courses typically cover organic reactions. On this reference sheet, the five types of organic reaction mechanisms are explained and an example is shown. For each, there is also a diagram of the chemical reaction that displays the movement of electron pairs from one compound to the other. Give this to chemistry learners during your lecture on the topic and let them keep it as a reference.
In this chemistry interactive quiz, learners answer 15 multiple choice questions on chemical bonding, enthalpy and Lewis structures.
In this chemistry worksheet, learners measure the different vibration levels of energy. They use the fundamental vibration frequency formula to calculate the Morse potential for a given chemical bond. There are 2 questions.
Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the challenge and also become more aware of tomorrow's technology!
Consider our energy sources: wood, coal, oil, uranium. Learners compare the pollution to energy produced for each. They practice fractional distillation of an alcohol/water mixture to simulate the process of refining crude oil. Thought-provoking questions are assigned as a follow-up to the laboratory exercise. This is an outstanding resource to add to your physical or earth science repertoire.
In this hydrocarbon learning exercise, students answer 13 questions about different types of organic molecules categorized as hydrocarbons. They explain the different hydrocarbons, they draw structural diagrams for different hydrocarbons and they calculate heat released by reactions of hydrocarbons.
So how does the carbon cycle work? Kids participate in a hands-on activity that allows them to understand the chemistry behind climate change and global warming. They act out the process of photosynthesis by labeling themselves as chemicals moving in and out of a plant. They form chemical bonds by linking arms to create different molecules that change from carbon dioxide to oxygen. To evaluate understanding, they respond to several prompts in writing. The concrete manner in which the topic is conveyed is great for both younger and older students.
