A chemical change
physical change
Chocolate milk is a mixture because it is made by combining chocolate syrup or powder with milk. The ingredients do not undergo a chemical reaction to create chocolate milk.
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, because you are not permanently changing the substance. Also you can change the two substances back to how they originally were
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.
A chemical change
When a chocolate bar melts in the sun, it is a physical change. This is because the chocolate undergoes a phase change from a solid to a liquid without changing its chemical composition.
Physical, Since only the property of the chocolate didn't change, after it melted, it still is chocolate

Physical because on the appearance of the chocolate bar changed
Melting chocolate is a physical reaction because it does not change the chemical composition of the chocolate. It only involves the change in state from a solid to a liquid due to the application of heat.
Chemical; you are changing the physical properties of the tortilla. Physical would be just warming or cooling it for example
