Vinegar (acetic acid solution in water) and salt (sodium chloride) are compounds, not"changes".
No. It is a change in phase. All changes in phase or state are physical changes, as it is still vinegar and a chemical change MUST result in a new compound being formed.

its a chemical change because you cannot reverse the process and just have milk and vinegar separate
If baking soda reacts with vinegar, it is a chemical change.
CHEMICAL
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! http://www.wikihow.com/Make-Cheese-at-Home
It is a physical change because the chemical composition of salt and water do not change. You can separate the salt and water physically by allowing the water to evaporate, which leaves the salt.
Physical change
This is a physical change because any reaction occur.
It is a chemical reaction and this is the correct way to spell penny!

The difference between chemical and physical changes is that chemical change is when a new substance is formed, and the reaction is irreversible. So as salt and vinegar do not react, it is indeed a physical change.
