Yes
No, the thickening of syrup when placed in the refrigerator is not a chemical change; it is a physical change. This thickening occurs due to the decrease in temperature, which affects the viscosity of the syrup without altering its chemical composition. The syrup can return to its original consistency when warmed, demonstrating that no new substances were created.
The flow of this liquid is a physical phenomenon; but the formation of this "syrup" is a chemical change.
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.
Making maple syrup involves both physical and chemical changes. The physical change occurs as the maple sap is evaporated to concentrate the sugars. The chemical change occurs as the sugars in the sap caramelize and develop the characteristic flavor of maple syrup.
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.

Mixing without a reaction is not a chemical change.

Dissolving chocolate syrup in milk is a physical change because it does not alter the molecular structure of the substances involved. The chocolate syrup particles mix with the milk, but they do not undergo a chemical reaction to create new substances.
Simple syrup can last for about one month in the refrigerator before it expires.
Yes, heating coconut milk until it turns into brown syrup is a chemical change. The heat causes the milk's proteins and sugars to undergo a series of complex reactions that lead to a change in its color, consistency, and flavor, creating a new substance with different chemical properties.
To prevent simple syrup from freezing in the refrigerator, you can add a small amount of vodka or other high-proof alcohol to the mixture. This lowers the freezing point of the syrup, keeping it in a liquid state.
Strawberry syrup primarily involves the chemical reactions of extraction and fermentation. When strawberries are cooked with sugar, the heat breaks down cell walls, releasing juice and flavor compounds through a process called maceration. Additionally, enzymes present in strawberries, such as pectinase, help break down pectin, thickening the syrup. If fermentation occurs, yeast may convert sugars into alcohol and carbon dioxide, although this is typically not a desired reaction in syrup production.
