Yes, when you add an acid, like vinegar, to milk a chemical reaction occurs. The acid causes milk to curdle. In fact, by adding vinegar to milk you can make cheese!

its a chemical change because you cannot reverse the process and just have milk and vinegar separate
When vinegar is added to milk, a chemical reaction occurs causing the milk to curdle and form lumps. This is due to the acid in vinegar causing the proteins in the milk to denature and clump together, separating into curds (solid) and whey (liquid). To show this, you can pour vinegar into a beaker of milk and observe how the milk starts to curdle and separate into curds and whey.
It makes casein ,a type of rock or hard like substance
The chemical reaction responsible for curdling milk involves the denaturation of protein, primarily casein, by an acid like lemon juice or vinegar. This denaturation causes the proteins to unfold and stick together, forming curds. The chemical equation is complex and involves various molecules and ions, but the key reaction involves the breakdown of the protein structure due to the acid.
The curdling of milk is a chemical process. It occurs when proteins in the milk, such as casein, interact with an acid (like lemon juice or vinegar), causing the proteins to denature and clump together, forming curds. This process is irreversible and results in a change in the composition of the milk.

This reaction doesn't exist, milk is a mixture.

The product of this chemical reaction is casein, a protein.

Mixing milk and vinegar is generally considered an irreversible process. When vinegar (an acid) is added to milk, it causes the proteins in the milk to curdle and form solid lumps, which cannot be returned to their original liquid state. This chemical reaction alters the composition of the milk, leading to the formation of curds and whey, making it difficult to separate and restore the original ingredients.
Mixing ketchup and milk is unlikely to create a significant chemical reaction. However, the combination may result in curdling due to the acidity of the ketchup interacting with the proteins in the milk. This can alter the texture and taste of the mixture.
Cereal and milk is a physical mixture, not a chemical one. When you pour cereal into milk, it doesn't create a new substance through a chemical reaction. The components of cereal and milk retain their individual properties.
Vinegar is an acid with a low pH. Milk is a complex mixture that has specific protein. When pH of milk drops too low, the casein protein denatures (breaks down) and binds differently to other proteins. The vinegar dropped the pH of the milk too low and this caused the curdling.

Chocolate milk is a mixture, as it is made by mixing chocolate syrup or powder with milk. It is not a chemical, compound, or a reaction.
