Department of Curriculum and Pedagogy Chemistry Chemical Reactions : exothermic and endothermic Science and Mathematics Education Research Group Supported by UBC Teaching and Learning Enhancement Fund 2012-2013. Endo/ exothermic Reactions 2H2 + O2. Energy 2H2O. Time Endo/ exothermic Reactions I. Which of the answers correctly completes the following statement? _____ Chemical bonds requires energy and _____ Chemical bonds releases energy. A. Forming / Forming B. Forming / Breaking C. Breaking / Breaking D. Breaking / Forming E. None of the above Solution Answer: D. Justification: The complete statement is: Breaking Chemical bonds requires energy and forming Chemical bonds releases energy. To understand this statement, think about 2 magnets. A. Chemical bond is like when they are stuck together. To pull 2. magnets apart you have to apply force (putting in energy). To put 2 magnets together (positive side to negative side), you don't have to do anything.

Chemistry Chemical Reactions: Exothermic and Endothermic Science and Mathematics Education Research Group ... would it be endothermic or exothermic? Solution Answer: C Justification: 2K + S K 2 S is a synthesis reaction because 2 compounds are reacting to form 1 new compound.

B) As the crate is being pulled up the incline, the height of the crate above the ground is increasing, therefore increasing its gravitational PE. C) The net work done on the crate IS zero because the box is not accelerating. With no acceleration, there is no net force. With no net force, there is no net work done on the crate.

The light that enters the eye that appears to come from the center image has undergone two reflections, one from each mirror. The third image is created here by the red rays. Light travels from the object to the mirror. It then reflects to the second mirror. Image 3 forms behind this second reflection. An imaginary line exists between the
