Yes, burning of a sparkle is a chemical change because once sparkle has changed its form it cannot come into its previous form. For understanding you can also take the example of cooked rice which once cooked cannot be raw again.
physical change
This is a chemical reaction; oxygen is released.
A chemical change
Chocolate milk is a mixture. It is not a change of any sort. The making of chocolate milk is a physical change as none of the components change their chemical identity.
Chocolate syrup being a thick liquid is a physical change, as the state of matter is altered but the chemical composition remains the same. If the chocolate syrup were to change in composition, for example by caramelizing or burning, it would be considered a chemical change.
physical change
Burning chocolate is a chemical change because the heat causes the chemical structure of the chocolate to change, leading to the release of new compounds and altering the composition of the chocolate.
Heating a frying pan is a physical change. A chemical change is when you change the chemical properties. Heating the pan is only changing the temperature of the pan not the chemical make up.
It is not a chemical change, unless you heat it sufficiently to make it catch fire.

Heating is a physical change.
A chemical change
Yes, heating red lead in a test tube is a chemical change. The process of heating causes the red lead to undergo a chemical reaction, leading to a change in its chemical composition. This change is irreversible.
Chocolate milk is a mixture. It is not a change of any sort. The making of chocolate milk is a physical change as none of the components change their chemical identity.
Heating KClO3 and MnO2 to form KCl and MnO2 is a chemical change as new substances are being produced.
