Is milk souring a physical change?
It is not physical but rather chemical: milk sugar (lactose) is converted to lactic acid by Lactobacillus bacteria.
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.
Which of the following involves a chemical change combinding an acid and a base dew forming or souring milk?
Souring milk involves a chemical change where lactic acid is produced by the fermentation of lactose in milk by bacteria. This is not the result of combining an acid and a base, but rather the conversion of lactose (a sugar) into lactic acid.
What is a physical change Milk becomes sour an iron nail rusts?
A physical change refers to a change in appearance or state that does not alter the chemical composition of the substance. When milk sours, it undergoes a physical change because its appearance and taste change, but the molecules remain the same. Similarly, when an iron nail rusts, it is a physical change because the iron's appearance changes as it forms rust, but the chemical composition of the iron is not altered.
Souring of milk is an example of a?
Souring of milk is an example of a fermentation process. This occurs when bacteria in the milk convert lactose (milk sugar) into lactic acid, causing the milk to thicken and develop a tangy flavor. This process is commonly used to create products like yogurt and cheese.

Is milk sours a physical or chemical change?
chemical change
Is milk sours a example of physical change?
No, milk souring is an example of a chemical change. When milk sours, bacteria ferment the lactose in the milk, producing lactic acid, which changes the composition and properties of the milk. This is a chemical reaction, not a physical change.

What are the properties of milk?
souring is the property of milk
What is Milk going sour is physical or chemical?
Chemical. If anyone wants to put more detail, please do.
Is milk souring a chemical or physical change or both?
Well just to start off nothing can ever be a physical and chemical change it has to be one or the other.. and the best way to know which one it is is a physical change doesnt change the substance and a chemical change will change the substance into something else. So milk going sour would be chemical because it isnt regular milk anymore its sour milk. but if it was something like evaporating water then it would be physical because its still water its just in the gas state. -Hope that helps(:
