Grape Juice contains mostly glucose (C6H12O6) and wine also has ethanol (C2H5OH). The ethanol is produced by fermentation of glucose by yeast cells. This is a chemical change.
It is a chemical change because it can not be reversed
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.
No!
physical change
Yes, grape juice is slightly acidic
Fermenting is a chemical process.
Chemical change.
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.
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.
it is a chemical
Floating is a physical property, and is not a 'change' in any sense.
