Physical changes are like water turning into ice, they can be reversed. Chemical changes form a new substance. Soured milk can not be reversed, so it is chemical.
chemical change
The chemical reaction between calcium carbonate and milk involves the formation of calcium ions (Ca2+) along with other products. The calcium ions may bind with proteins in milk, such as casein, forming complexes that can precipitate out of solution. This can result in the formation of a residue or sediment in the milk.
Milk turning sour is a chemical change. It occurs due to the fermentation of milk sugars by bacteria, leading to the production of lactic acid, which changes the taste and smell of the milk.
The reaction between milk of magnesia and the acids in your stomach is a neutralization reaction. The magnesium hydroxide in milk of magnesia reacts with the acidic stomach contents to form magnesium chloride and water, thereby neutralizing the acidity.
The active ingredients in Milk of Magnesia is Magnesium hydroxide. Milk of Magnesia is a liquid laxative and antacid that looks like milk.
yes See Is Sour Milk a physical or chemical change for more info
Cereal and milk is a physical mixture, not a chemical one. When you pour cereal into milk, it doesn't create a new substance through a chemical reaction. The components of cereal and milk retain their individual properties.
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.
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.
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
Mixing hot coffee with cold milk is a physical change because the molecules of both substances do not undergo a chemical reaction. The temperature change occurs due to heat transfer from the coffee to the milk, but the chemical composition of the coffee and milk remains the same.
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.
Dissolving chocolate syrup in milk is a physical change because it does not alter the molecular structure of the substances involved. The chocolate syrup particles mix with the milk, but they do not undergo a chemical reaction to create new substances.
Milk thickening is generally considered to be a physical change because it involves a change in the physical state of the milk without altering its chemical composition. Heating milk causes the proteins to denature and form a network that traps water molecules, resulting in a thicker consistency.
Physical.
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.
yes, its a chemical reaction between the acid in the redbull and the casiene in the milk which causes the fluffiness when the casiene seperates from the milk due to the acid.
