This is a physical change because any reaction occur.
No, it is a chemical change. A chemical reaction occurs when the two are mixed-- bubbling/fizzing.
its a chemical change because you cannot reverse the process and just have milk and vinegar separate
chemical I do believe. Here's why- the substances within the mixture will create a gas as they react. A chemical change is simply a change that results in one or more new substances.
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.

Yes, it is chemical

Kind of tricky question, because on the surface, one might not think that cornstarch and vinegar (acetic acid) don't react chemically. But, in fact, there can be a chemical reaction under the right conditions. So, it would probably be safe to say "chemical" change, if given the chance, but it could also be just a physical change if conditions aren't right.
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
