Exothermic Reactions

Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical composition...

For advanced chemists, this worksheet examines heat change during chemcial reactions. Alkanes are examined first. Learners calculate the energy released or needed during a reaction.

Start this series of lessons with a bang! Five exothermic reactions are outlined in this resource, including a demonstration that produces both light and sound. In the lab, chemistry apprentices record temperature changes, make hand...

Chemistry whizzes test the change in water temperature produced by a burning candle and the change in acid temperature produced by magnesium metal. With these two laboratory activities they explore heat produced during chemical...

If your pupils think a catalyst is a list of their cats, then this might be the lesson for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

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...

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...

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

Ladies and gentlemen, start your engines! Explore the cumbustion reactions driving the world's automobiles and the chemical solutions used to keep their engines cool with this fun instructional video.

Chemical reactions are happening all around us every second of every day, but what exactly causes these changes to occur? Using easy-to-understand analogies, this video explains how the concepts of enthalpy and entropy determine the ways...
