When ethanol is burned, it's converted into carbon dioxide and water. Does the ethanol undergo a physical change or a chemical change? Explain.
Answer (2)
It's a chemical change because ethanol is converted into other substances.
Ethanol undergoes a chemical change when burned because it transforms into new substances: carbon dioxide and water. This process involves breaking and forming bonds, resulting in products that are chemically different from the original ethanol. Therefore, the act of burning ethanol is a demonstration of a chemical reaction.
