Homework help for chemistry...please.

[From: ] [author: ] [Date: 11-09-08] [Hit: ]
chemical changes are changes in which the element or chemical becomes a new substance.rust, paper burning (both), burning hydrocarbons for fuel, reacting 2 or more elements together to create a compound, etc.......
Can someone give me 3 examples of a chemical change. I may have 1 answer, but i don't know if it's a good one.

If you want to, anyone can give me 2 examples since i may already have 1.

Clarification:Does carbon dioxide break down into carbon and oxygen? And is this a chemical change?

-
CO2 does not break down into C and O2 unless it is heated a great deal. CO2 is a stable gas.

chemical changes are changes in which the element or chemical becomes a new substance. rust, paper burning (both), burning hydrocarbons for fuel, reacting 2 or more elements together to create a compound, etc.
