Chemical reaction equation examples
WebAn example of an electrolytic decomposition reaction is the electrolysis of water, which can be represented by the following chemical equation. 2H2O → 2H2 + O2 To learn more about the different types of chemical reactions, register with BYJU’S. Test your Knowledge on Decomposition reaction! WebFor example, freezing or boiling water is a physical change. Once melted or boiled, the water may be in a different form (solid ice or gaseous water vapor), but it is still water, H 2 O, and it still has the same chemical composition. A chemical change happens when a substance’s chemical identity changes. An example of this is rusting.
