In a Chemical Change, atoms rearrange to form one or more new substance. They do this by breaking bonds and forming new ones.
The identity of the substance undergoing the change is altered. In short: it depends on the chemical change.
You would see a gas given off, the colour might change and it may change states that can not be turned back to what it was.

hope I've answered your questio :)
During a chemical change, the properties change and a new substance is formed. Temperatures change, colors change or smoke is present, and/or gas/bubbles are released
A new substance is created and heat, light, or gasses are given off.
Even though the persons answer is very well explained (down below) but I think you are looking for a more simple answer which is: Burning Paper

A new chemical is formed. Evidence of this is cooling or heating of the samples as well as bubbles meaning a gas is formed.

Vinegar and baking soda form a gas and it bubbles.
Forms different substance.
