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.
During a chemical reaction, one chemical reacts with another chemical and produces a different substance, but with the same number of each atom.
In all chemical chemical changes the reactants are transformed in products, with other composition.
tranfer of energy, solid, color, gas
the element
chemical change
Physical. Physical changes include things such as changing shape or color. Chemical changes change the chemical properties of a material, often during a chemical reaction.
It is a chemical change because the ammonium dichromate changes color, explodes, and probably creates a gas during the change.
Actually both physical and chemical changes are happening during cement mixing.
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
Yes it is released/ absorbed during chemical changes.
During a chemical change the molecule is transformed; during a physical change the molecule is not transformed.
This process involve chemical reactions but also physical changes.

Yes. Chemical changes occur during the calcination of ceramics for pottery.
There are no chemical changes.
Physical. Physical changes include things such as changing shape or color. Chemical changes change the chemical properties of a material, often during a chemical reaction.
yes chemical properties do change a substance physical properties just change the physical shape or look!!!
It is a chemical change because the ammonium dichromate changes color, explodes, and probably creates a gas during the change.
Yes. Chemical changes are irreversible, but physical changes can easily be changed back
Actually both physical and chemical changes are happening during cement mixing.
