The nasty foods you eat that are stuck in your teeth.
Grilling milkfish is a chemical change because the heat causes the proteins in the fish to denature and undergo chemical reactions that change its composition and flavor.
Toasting bread is a chemical change because the heat causes chemical reactions to occur within the bread, leading to a browning effect and changing the chemical composition of the bread.
It is a chemical process. The diesel gets compressed with air which in turn causes heat which in turn causes combustion.

Souring milk causes a chemical change because it changes its state of matter (from a liquid to a semi-solid), and it grows bacteria. When milk sours it causes a permanent change, therefore making it a chemical change.
Breaking a toothpick is a physical change because it only affects the physical appearance of the toothpick, not its chemical composition. The molecules in the toothpick remain the same even after it is broken.

It is true that a chemical reaction causes a chemical change. An example of this can be seen by adding baking soda to vinegar.

Yes. The charging causes a chemical change in the electrolyte of the battery.

Toasting bread is a chemical change because the heat causes chemical reactions to occur within the bread, leading to a browning effect and changing the chemical composition of the bread.
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.
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.
Boiling potatoes is a physical change, not a chemical change. The heat causes the starch in the potatoes to gelatinize and the cells to rupture, but the chemical composition of the potatoes remains the same.
It is a chemical process. The diesel gets compressed with air which in turn causes heat which in turn causes combustion.
