If you created something new. If you combined 2 chemicals and there was a line of lets say yellow in the middle, the yellow line would be the chemical change because you have created something new.
no, breaking wood is a physical change.If the wood was burned, that would be chemical change
an example of a chemical change is burning. there are, of course, many others.
No, milk souring is an example of a chemical change. When milk sours, bacteria ferment the lactose in the milk, producing lactic acid, which changes the composition and properties of the milk. This is a chemical reaction, not a physical change.
The rusting of an iron pole is a chemical change. An example of a chemical change would be crumbling a piece of paper. When you are crumbling this piece of paper, the contents of the paper have not change and you are able to uncrumble the paper there is no difference except the paper has wrinkles. :) However in an example of chemical change like a metal rusting, you cannot un-rust it, it was chemically changed. Another example of a chemical change would be burning a piece of paper to ashes.
rust is a chemical change for iron
No, That would be a physical change....A chemical change would be for like example: Water Evaporting, Water Boiling, Water Freezing...etc
no, breaking wood is a physical change.If the wood was burned, that would be chemical change
I suppose that would be a summary of a change which is not chemical. Perhaps it would be something like ice --> water
For example adding a base.

Rusting is the oxidation of a metal and is an example of a chemical change.
Cooking is for example a chemical change.
I would think it to be a Physical Change. Not chemical.
