For one, heterogeneous catalysts can be separated from a reaction mixture in a straightforward manner, such as by filtration. In this way, expensive catalysts can be easily and effectively recovered, which is an important consideration for industrial manufacturing processes.
Combination Reactions In a combination reaction the atoms and/or molecules do what the name implies: they combine to form the product. Combination reactions are always exothermic.For example barium metal and fluorine gas will combine in a highly exothermic reaction to form the salt barium fluoride: Another example is given by magnesium oxide combining with carbon dioxide: Often, reaction can fall into more than one category.ombination Reactions In a combination reaction the atoms and/or molecules do what the name implies: they combine to form the product.
