Find the missing △H°f using △H°rxn. And if that's not fun enough, find △H°rxn using some awesome formations such as water(g) or maybe its (l). That's for them to decide... 1) Problem 1 requires students to write 3 challenging (fractions) standard formation equations which have enthalpy numbers that can only be found in problems 2-6. In problems 2-6 they are required to determine the △H°f for substances (the ones in problem 1) from some cool thermochemical reactions. They also have to find △H°rxn

In this activity, students will calculate the Enthalpy of Formation △H°f for both Calcium Carbide and Nitrogen Dioxide using thermochemical data and Enthalpy of Reaction. 1. Two quizzes print per page. The first page is Calcium Carbide and the second page is Nitrogen Dioxide. The third page combines both problems into one larger quiz. 2. All thermochemical data is conveniently provided with each problem - No need for any annoying appendixes or tables;) 3. A key is included. Thank you and Enjoy

This fun activity presents students with a series of Hess's Law challenges where that have shapes instead of chemicals in the thermochemical reactions. The goal with each challenge is to use Hess's Law to find Enthalpy of Reaction. This activity is formatted to be used as warm-ups or quizzes. There are 3 problems in total and there are 3 formats for printing. The full page version (page 3) includes all three Hess Law problems. The other 2 versions are individual problems that print 2 quizzes

In this activity, students calculate the Enthalpy of Reaction △H°rxn for the combustion of propane and benzene first using the formations method and next using their bond enthalpies. Students will see how both methods get them similar yet slightly different enthalpies for the same substance. Thank you and Enjoy! Please leave feedback and click the FOLLOW button!!!

How could an error lead to one of the greatest discoveries in chemistry? We shall soon see! This study guide is for Chapter 8 of The Mystery of the Periodic Table*--- "Mr. Priestley Clears Things Up." In Chapter 8, we are given a brief history of Joseph Priestley and how he "clears things up" - (sort of). In his most famous experiment, the one where he "trapped" oxygen and erroneously calls it dephlogisticated air, Priestley demonstrates how an error can bring us closer to the truth. I typi

This study guide is for Chapter 7 of The Mystery of the Periodic Table*--- "The Strange Tale of Phlogiston." In Chapter 7, we are introduced to Johann Becher and his False Theory of Phlogiston. How could a misconception lead to one of the greatest discoveries? We shall see! I typically wait until after we finish reading the chapter to pass out the study guide. This ensures that students focus only on reading the 1st time through. This study guide comes with 27 questions about the text, or

This quiz is for chapter 6 of The Mystery of the Periodic Table*--- "The Atomists Return." For this quiz, students are given a summary of chapter 6 with blanks in the place of important key terms. They are required to use an Answer Bank to locate each missing term. This exercise not only tests their retention of the text, but also reinforces their knowledge of the greater themes in the book. This quiz should take around 10 minutes. 2 print per page. A key is included. Enjoy! *The Mystery of

This study guide is for Chapter 6 of The Mystery of the Periodic Table*--- "The Atomists Return." In Chapter 6, the concept of atomism reemerges with Robert Boyle as its champion. I typically wait till after we finish reading the chapter to pass out the study guide. This ensures that students focus only on reading the 1st time through. This study guide comes with 30 questions about the text, original art, years of experience, and a key. Thanks and Enjoy! *The Mystery of the Periodic T

Empower your students with Flip Cards! You print them, cut them out, and your students solve quantitative analysis problems that were never before possible! Conversion factors can be as frustrating to teach as they are for students to learn. This activity, empowers both you and your students by giving them the tools and framework to be successful. This document includes: 1. 12 printable Flip Cards with intuitive graphics applicable to this set of questions and more... . 2. Instructions for how t

Conversion factors can be as frustrating to teach as they are for students to learn. Flip cards empower both you and your students by giving them the tools to successfully execute complex unit conversions. More specifically, this resource includes: 32 printable Flip Cards with intuitive graphics. When printing Flip Cards: be sure to use card stock. Each page contains 32 colorful conversion cards.

In this activity, you are asked to use bond enthalpies to estimate the ∆H for 5 colorful reactions. You are also asked to identify whether each reaction is exothermic or endothermic. Building upon the prior conclusion you are to identify which has the higher enthalpy: the reactants or the products. This step requires a deeper analysis of the exchange of energy during a reaction. Along with the 2 page worksheet, a table of bond enthalpies and a key are included. Thank you and Enjoy! Please leave

Isomers are compounds that have identical chemical formulas but have a different structure. In this activity, you are asked to use bond enthalpies to estimate the ∆H for 4 colorful isomerization reactions. You are also asked to identify which isomer has the higher enthalpy. This step requires a deeper analysis into the exchange of energy during a reaction. Along with the 2 page worksheet, a table of bond enthalpies and a key are included. Students do not need prior knowledge of isomers to tackle

This resource comes with 4 reactions in which you are required to use bond enthalpies to find the enthalpy of reaction. Each reaction is its own quiz and 3 quizzes print per page. Also included is a quiz "abcd" that has all 4 reactions on one page which might be more convenient for you. A key is included. Thank you and Enjoy!

There is no better way to start class than with a Hess's Law quiz! It keeps them busy for about 10 minutes which buys you time to figure out what to do with them for the next 40 minutes;)... and if nothing comes, you can pass out the other 2 quizzes. This document comes with 3 Hess's Law problems that print 3 per page. A key is included. Thank you and Enjoy! Also, check out my other Hess's Law activities! .

The 5 basic reaction types have specific patterns which allow us to predict their products. In this activity students are asked to analyze the reactants of each reaction and predict the products. In addition, they are required to balance each reaction. The first page has 8 reactions that are missing their products. This page provides a great platform for instruction. The second page is for you! It follows the same "missing substance" format except it has an ANSWER BANK which means less hands wi

This worksheet comes with 12 combustion reactions just waiting to be balanced! Everyone has their "best" way to balance a combustion reaction. I prefer to balance C, H, then O last. If I get a .5 on O2 then I multiply all coefficients by 2 to get my final coefficients. But I'll leave that up to you and your students. That said, there is plenty of space between reactions to implement any "best" method;) This worksheet prints on one page front and back. A key is included. Enjoy

An isoelectronic series is a group of ions that have acquired the same electron arrangement as a noble gas. In this quick activity, students are asked to sort each ion and noble gas into its isoelectronic family according to its number of electrons and ionic charge. The beautiful pattern will become evident as this activity unfolds! For students to be ready for this activity, they must have been taught atomic structure, ions, and isotope notation. 2 print per page. A key is included. Enjoy!
