Combination reaction exothermic
WebA synthesis reaction is a type of reaction in which multiple reactants combine to form a single product. Synthesis reactions release energy in the form of heat and light, so they are exothermic. An example of a synthesis reaction is the formation of water from hydrogen and oxygen. Synthesis is, in essence, the reversal of a decomposition ... WebBut not all combination reactions are exothermic. There are some exceptions such as when nitrogen combines with oxygen and forms nitrogen oxide. In this reaction, a lot of heat needs to be given in. So this is an endothermic reaction. But we'll talk a lot about energy given out and energy required in a separate video called exothermic and ...
