Yes it is because it is not reversible, and the butter changed colour.
A chemical reaction in a hot air balloon can be when the propane is heated up. That is a chemical reaction because something has heated up.
The chemical decomposition is:CuSO4------ CuO + SO3
The equation is: CaCO3------CaO + CO2
Decomposition
I was thinking of boiling water, but that's physical
When the egg is in its liquid form and then heated, a chemical reaction between the protein and amino acids cause it to harden therefore making your "Became chemical change"
A reaction of oxydation with the oxygen from air.

It may speed up when heated.
Yes there is a chemical reaction called 'Effervecense'.
They do something, or have a chemical reaction
A chemical reaction
The chemical decomposition is:CuSO4------ CuO + SO3

the mass increases during a chemical reaction. because if heated or cooled then it would put on more mass for the atom.
The chemical reaction is:2 Fe(s) + 3 Cl2(g) = 2 FeCl3
when a flammable chemical such as oil (ancient tree) gets heated up to much it acts as a chemical reaction it catches on fire
