Are all exothermic reactions combination reactions |
| Answer» Combination reactions\xa0are\xa0always exothermic. For example barium metal and fluorine gas will combine in a highly\xa0exothermic reaction\xa0to form the salt barium fluoride: Another example is given by magnesium oxide combining with carbon dioxide: Often,\xa0reaction\xa0can fall into more than one category.\xa0Most of the\xa0combination reactions\xa0are\xa0exothermic\xa0but not\xa0all\xa0the\xa0combination reactions\xa0are\xa0exothermic\xa0similarly most of the decomposition\xa0reactions\xa0are endothermic but not not\xa0all\xa0the\xa0reactions\xa0are endothermic. For Example oxidation of hydrocarbons is\xa0exothermic. | |
