Homework Help: chemistry

Posted by astrid on Monday, October 26, 2009 at 8:05pm.

we did a bunsen burner lab where we burned paper clips. We burned it for about 10 seconds then cooled it in water. I know this is a physical change but i need to come up with 3 chemical changes that occured. I already came up with the water vapor that occurs when it cools down and i need two more examples.

Thank you!
