When hydrogen peroxide bubbles, it is undergoing a chemical change. Which statement best describes what is happening? The atoms in hydrogen peroxide are breaking apart and forming new types of molecules. Four students are analyzing four different substances and recording their findings in this table.
When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated. An example of a chemical change is the reaction between sodium and water to produce sodium hydroxide and hydrogen.So much energy is released that the hydrogen gas released spontaneously burns in the air.n example of a chemical change is the reaction between sodium and water to produce sodium hydroxide and hydrogen.
