it changes the color of cornstarch

No, its a physical reaction.
No, mixing cornstarch with water is not a chemical reaction. It is a physical change. The cornstarch particles disperse throughout the water, but no new substances are formed.
Baking soda and vinegar create a chemical reaction when mixed together. When the two substances combine, they produce carbon dioxide gas, which leads to fizzing and bubbling. Epsom salt and vinegar do not typically react with each other in the same way.
Oh, dude, when you mix cornstarch with vinegar, you get a non-Newtonian fluid! It's like this weird, gooey substance that acts like a solid when you apply force to it, but then flows like a liquid when you stop. It's like magic, but with more science and less rabbits in hats.
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.
When soda (carbonated water) and vinegar are mixed together, a chemical reaction occurs that produces carbon dioxide gas. This reaction causes fizzing and bubbling, as the gas tries to escape from the liquid mixture. The reaction is a result of the acid in vinegar reacting with the carbon dioxide in the soda.

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.
When cornstarch is mixed with vinegar, it makes a cloudy solution. It cannot dissolve in the vinegar, so it creates a liquid that has cornstarch particles floating in it turning the liquid cloudy.
This is a neutralization reaction; sodium acetate is obtained.
When baby powder, which typically contains talc or cornstarch, is mixed with vinegar, a mild reaction occurs primarily due to the acetic acid in vinegar interacting with the components of the powder. While there may not be a dramatic chemical reaction, the vinegar can cause the powder to clump or dissolve, altering its texture. This reaction is often used in educational demonstrations to illustrate changes in states of matter or to explore basic acid-base interactions.
It bubbles up
No, it is a chemical change. A chemical reaction occurs when the two are mixed-- bubbling/fizzing.
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
CH3COOH + NaHCO3 = CH3COONa + CO2 + H2O
This is a physical change because any reaction occur.
The reaction between acetic acid (vinegar) and sodium chloride (table salt) does not result in a chemical reaction. When mixed together, they simply form a solution where the salt dissolves in the vinegar.
