yo ucan tell if there is a chemical change if there is a temperature change, color change,formattion of gas, precipitate,or a release of gasses
When a chemical reaction occurs, the properties, (colour , texture etc.) change, creating a new substance. e.g, Hydrogen gas and oxygen gas react to make water, a completely new substance
A chemical change occurs when atoms are rearranged or when bonds are broken. Chemical changes are normally hard to undo. Examples of chemical change includes burning or rusting.

You know a chemical change happened if: -A change in color -Formation of a precipate (a solid) -Formation of a gas
Well, grilling the bread is a chemical change, but the melting cheese I believe is a physical change.
Human growth is a chemical change because the organs inside your body react with a substance (I don't know what substance, but I know it reacts with somthing in your body) in your body

Can you reverse the change?
Its a chemical change because its changing what it is (from dough to bread)
Does anyone know
dont know your out of luck

don't know..... personally i think it is because it is a change and a change is a chemical reactions
It's a chemical change. A chemical change is any change that causes a substance to change into another substance. A sign to know whether it's a chemical change or not, are the changes in odor. When something decays the change in smell is very powerful. Therefore, it is a chemical change.

Burning is a chemical reaction, an oxydation.
Not as far as I know. I think it's still My Chemical Romance, they had no reason to change it. so, yeah... they better not have! ;)
