Question

Sierra and Katie were sitting around the campfire, getting ready to roast some marshmallows. They remembered that they were studying physical and chemical changes in Science. Sierra thought the wood burning in the pit showed a chemical reaction but Katie wasn't sure. Write a few sentences to help Katie understand why the burning wood is demonstrating a chemical reaction. PLEASE I NEED EXTRA HELP

Answer 1

Answer / Explanation:

Burning is a non-reversible chemical change. When you burn wood, the carbon in the wood reacts with oxygen in the air to create ash and smoke, and energy in the form of light and heat. This is a permanent change that cannot be undone – you cannot turn ashes back into wood.
