Yes it is, as the browning of the bread when you toast it, is a reaction between the reducing sugar and amino acids. The reaction is called Maillard reaction.
In simpler words, the bread is being "burned" which is a chemical change as it cannot be reversed. You can't get back the same soft,fluffy, white bread after you toast it.

No, it's a physical because there was no change in it's chemical substance
Toasting bread is an example of a chemical change because a chemical change cannot be reversed and a physical change can and toasted bread cannot be turned back into normal bread.
yes it is
It is a chemical change because some compounds from bread are thermally decomposed.
Chemical Change - Someone toasting bread until it is crisp. (Or just cooking in general, but does not apply to all types of food)Physical Change - Someone pouring one of those Crystal Lights into water.
This is a physical change and might include a chemical change due to the heat involved in taking the bread to its final appearance. the physical change because, there is a change in color(colour) and a slight change in shape depending on the toaster you are using.
Toasting a marshmallow is actually a chemical change. The marshmallow becomes black and crispy, it also no longer tastes the same. Thus, it is a chemical change.Roasting a marshmallow is an example of a chemical change. Generally when you heat food in the process of cooking, you will cause a chemical change.
A physical change. A chemical change would be, for example, burning clothes, or dissolving clothes.

Toasting bread represents a chemical change.
It is a chemical change because some compounds from bread are thermally decomposed.
Physical ------------------- It is a chemical change because some compounds from bread are thermally decomposed. The reaction is not reversible.
No it's a chemical change as you can't 'untoast' the bread.
