WitrynaIn any chemical reaction, chemical bonds are either broken or formed. And the rule of thumb is "When chemical bonds are formed, heat is released, and when chemical bonds are broken, heat is absorbed."Molecules inherently want to stay together, … Witrynaanswer choices. hot and cold temperatures. energy to break and energy to form bonds. time to form a bond versus time to break a bond. Question 11. 20 seconds. Q. In a reaction old bonds _______ and new bonds _______. answer choices. glens falls transfer station hours
Bond Energy , Exothermic and Endothermic reactions
WitrynaChemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Chemical reactions that absorb (or use) energy are called endothermic. In endothermic reactions, more energy is absorbed when the … Witryna31 gru 2015 · Explanation: To break bonds, you must expend energy. When bonds are made, energy is released. Let's take the simple combustion of methane as shown: Looking at this reaction, I am breaking STRONG C − H and O = O bonds. But at the same time I am making even STRONGER C = O, and O− H bonds. The energy … WitrynaJustification: The definitions of endo/exothermic reactions are: Exothermic reaction energy is released Endothermic reaction energy is absorbed Thus, neither C nor D are correct ... endothermic reaction is the result of bonds breaking. A. Synthesis / endothermic B. Decomposition / exothermic C. Synthesis / exothermic D. Synthesis … body shop ft belvoir
