WebApr 23, 2024 · What happens in an exothermic reaction at the atomic level? In a chemical reaction, bonds are broken and bonds are formed. For example, when elemental oxygen and hydrogen form water, we are breaking bonds in the elements and making heteroatomic bonds connecting hydrogen and oxygen atoms: O X 2 + 2 H X 2 2 H X 2 O WebAug 19, 2024 · Self-heating cans operate by combining two chemicals in an exothermic chemical process. Aluminum with silica, calcium oxide and water, and copper sulfate and zinc are all popular pairings. The ammonium salt absorbs heat from the air surrounding it as it dissolves, reducing the water’s temperature to the freezing point.

WebStep-by-step explanation. A reaction is considered endothermic if it results in the accumulation of energy, while an exothermic reaction is defined as one that results in the loss of energy. When bonds are formed, exothermic reactions occur, and when bonds are broken, endothermic reactions occur. WebMay 17, 2024 · In this particular reaction, because the newly formed bonds release more energy than was needed to break the original bonds, the resulting system has a lower potential energy than the reactants. What happens to energy when bonds are formed? Energy is absorbed to break bonds. Energy is released when new bonds form. Bond …
WebAug 4, 2009 · Exothermic refers to a reaction that produces heat. When you balance the equation the energy released when new bonds are formed is greater than the energy use when bonds are broken. An...
