Mixing lemon juice and milk would result in a physical change. The two substances retain their original properties and do not create a new chemical compound when mixed together.
Mixing lemon juice with milk would be a chemical change because the acid in the lemon juice can curdle the proteins in the milk, leading to a change in the chemical composition of the mixture.
Mixing juice crystal in water is a physical change because no new substances are formed; only the physical state of the juice crystal changes as it dissolves in the water. It can be reversed by evaporating the water.
Squeezing oranges for juice is not a chemical change because it does not alter the chemical composition of the oranges. It is a physical change where the oranges are only being mechanically processed to extract the juice. The same chemical components of the oranges remain in the juice.
Putting a penny in lemon juice would cause a chemical change because the lemon juice reacts with the copper in the penny to create copper oxide, which changes the chemical composition of the penny.
Dipping blue litmus paper in lemon juice is a chemical change. The acidic nature of lemon juice causes a chemical reaction with the blue litmus paper, turning it red. This change in color indicates a chemical transformation of the litmus paper due to the interaction with the acid in the lemon juice.
Mixing lemon juice with milk would be a chemical change because the acid in the lemon juice can curdle the proteins in the milk, leading to a change in the chemical composition of the mixture.
Mixing juice crystal in water is a physical change because no new substances are formed; only the physical state of the juice crystal changes as it dissolves in the water. It can be reversed by evaporating the water.
it is physical because there is no new matter will produce(( water+ juice dissolved)) just
Squeezing oranges for juice is not a chemical change because it does not alter the chemical composition of the oranges. It is a physical change where the oranges are only being mechanically processed to extract the juice. The same chemical components of the oranges remain in the juice.
Yes, mixing lemon juice and milk results in a chemical change. The acid in lemon juice causes the proteins in milk to coagulate, leading to the formation of curds and whey. This process alters the composition and properties of the milk, indicating a chemical reaction has occurred.
No!
Fermenting is a chemical process.
Making diluting juice is a physical change because it involves mixing a concentrated juice with water, resulting in a new mixture without altering the chemical composition of the juice or water. The process is reversible; if the mixture is separated, the original components can be recovered. Additionally, the properties of the juice, such as taste and color, change, but the substances themselves remain unchanged at the molecular level.
it is a chemical
physical change
they're not bad, its the application you give to what you do, if you make a cake, you are chemical transforming flour into bread, if you make orange juice, you are physical transforming the orange into juice.
Putting a penny in lemon juice would cause a chemical change because the lemon juice reacts with the copper in the penny to create copper oxide, which changes the chemical composition of the penny.
