No, a chemical change.
Taste and smell are indicators of chemical composition, so a change in those would indicate a chemical change.

Is a bottle of milk that sours a physical or chemical change?
This is a chemical change.
Is chocolate milk an example of a chemical change physical change or a mixture?
Chocolate milk is a mixture. It is not a change of any sort. The making of chocolate milk is a physical change as none of the components change their chemical identity.
Is chocolate milk a n example of a chemical change physical change or a mixture?
Chocolate milk is a mixture called a colloid.
Milk goes sour a physical or chemical change?
It is a chemical change because there is a chemical reaction occurring that is rotting the milk. An example of a physical change would be if the milk was evaporated or frozen.
Why is churning a chemical change?
Souring milk causes a chemical change because it changes its state of matter (from a liquid to a semi-solid), and it grows bacteria. When milk sours it causes a permanent change, therefore making it a chemical change.

How is sour milk a chemical change?
milk going sour is a chemical change because it can't be reversed. Most physical changes can be reversed for example snow melting is a physical change because it can freeze again.
Is souring milk a physical or chemical change Why or why not?
It's a chemical change. The smell is the giveaway; a smell that wasn't there before is often an indicator of a chemical change. Also, the rate at which the milk sours can be changed by heat. For example, milk in the refrigerator is actually undergoing this souring reaction at all times, but the lower temperature inside the refrigerator slows it down so that it takes many days. But if you leave it outside the refrigerator, it will sour much more quickly - in a matter of hours. An increase in heat, therefore, quickens the reaction rate. This would not be the case in a physical change.
