Physical or chemical Reaction type and why? ELephant toothpaste
1 answer
Elephant toothpaste is a demonstration of a chemical reaction. It involves the decomposition of hydrogen peroxide (H2O2) by using a catalyst such as potassium iodide (KI) or yeast. The reaction generates oxygen gas (O2) and water (H2O) as products, along with the formation of a large foam due to the rapid production of oxygen gas. This reaction is a classic example of an exothermic decomposition reaction, which releases heat and energy in the form of gas.
