Is burning a match a chemical change or physical change?

Answer 1

I have this same worksheet that has the following questions that I have to answer: Iron rusts. Sodium hydroxide dissolves in water. A safety match ignites and burns. A cube of ice melts to form a puddle of water. Icicles form at the edge of a rof. Water is heated and changed into steam. Milk goes sour. A chocolate bar melts in the sun. Acid on limestone produces carbon dioxide gas. Vinegar and baking soda react. A tea kettle beings to whistle. Wood and leaves rot to form humus. So, I believe that a safety match igniting and burning is a chemical change. I have many Wiki results from that, and some put physical change. I don't think it's a physical change because the fire is on the match, and once it blows out, it creates that black substace which ISN'T fire. It creates a new substance that wasn't there before. Basically, the red part of the match and the fire created that new substance. I hope this helped! Sorry if this is wrong info. *-*

Burning anything is a chemical change. When something burns, the molecules of the substance are combined with oxygen, breaking the bonds in the molecule and forming new ones.
