The flow of this liquid is a physical phenomenon; but the formation of this "syrup" is a chemical change.
This is a physical process.
This is a physical change.
A chemical change involves a change in a substance's chemical make-up or conversion to a different substance. A physical change is one that involves changes in a substance's physical makeup that is not brought about by a chemical change, such as sugar dissolving in water. Therefore, mixing milk and chocolate syrup is not a chemical change. Now, if for some reason the syrup had a strong enough acid in it, and mixing the two made the milk curdle or solidify, then yes, it would be a chemical change.
Yes, as well as a chemical change. It clearly changes (white, granulated sugar and liquid to burned brown sugar and liquid to a sticky [and delicious] substance). It changes from a solution to a syrup!
None. You are creating a solution, but I do not believe it represents a change in either materials. If it is indeed a change, as I most certainly could be wrong, then it would be a physical one.

Mixing without a reaction is not a chemical change.

Unless you overdo it and carmelize it, it is a physical change. A typical process is to dissolve a large amount of sugar into hot water (physical change - the sugar is still sugar and the water is still water; they do not react. If the sugar-water is not syrupy enough, you can boil off some of the water (still a physical change). If you overdo it though, you will begin to caramelize the sugar. If the sugar is sucrose, it breaks down into fructose and sucrose along with a host of other side reactions that condense, isomerize, dehydrate, fragment, polymerize, and otherwise chemically change the original sugar. Caramelization is definitely a chemical change, but it is not necessary to make syrup.
no because itjust changes color and taste wich is a physical property
Yes, mixing milk with chocolate is just a physical and not a chemical action.
