Is milk souring an example of chemical change?
Yes it is a chemical reaction between the calcium and the oxygen [i may be wrong their] but the rate of reaction is very slow.
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.
Is an example of a chemical change a. ice melting c. pounding gold into a coin b. milk souring d. a puddle of water evaporating?
An example of a chemical change is b. milk souring. This process involves a chemical reaction where bacteria convert lactose in the milk into lactic acid, resulting in a change in the milk's composition and properties. In contrast, ice melting, pounding gold, and water evaporating are all physical changes, as they do not alter the chemical structure of the substances involved.
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.
Is chocolate milk a chemical a compound a mixture or a reaction?
Chocolate milk is a mixture, as it is made by mixing chocolate syrup or powder with milk. It is not a chemical, compound, or a reaction.
What do rusting cars and souring milk have in common?
Chemical reaction in both happens slowly.
Is souring milk an example of a chemical change?
Yes, souring milk is an example of a chemical change. The breakdown of lactose by bacteria into lactic acid changes the composition of the milk, resulting in a new substance with different properties.
Is milk souring an example of chemical change?
Yes it is a chemical reaction between the calcium and the oxygen [i may be wrong their] but the rate of reaction is very slow.
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.
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.
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.
In examples of chemical changes the odor of sour milk indicates a chemical change has taken place true or false?
True. The souring of milk is a chemical change caused by the breakdown of lactose sugars into lactic acid by bacteria. The change in odor is a result of this chemical reaction.
Is milk souring a physical change?
It is not physical but rather chemical: milk sugar (lactose) is converted to lactic acid by Lactobacillus bacteria.
Unscramble this please uoisrng?
Souring, as in Souring milk," Mom! This Milk Is Souring!" YUCK!!! ==Gee, sour milk...?== Now that's a "rousing" thought...
Is milk sours a physical or chemical change?
chemical change
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.
What are the properties of milk?
souring is the property of milk
