what evidence would you look for in a chemical change
Since this is not my area of expertise, I searched Google under the key words "disaccharide" to get these possible sources:

http://en.wikipedia.org/wiki/Disaccharide
http://academic.brooklyn.cuny.edu/biology/bio4fv/page/disaccharide.html
http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/C/Carbohydrates.html

You can do the same for "lactose." In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.
First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where is more likely to be overlooked.

Second, since this is not my area of expertise, I searched Google under the key words "'chemical change' evidence" to get these possible sources:
