The number of free (acidic) protons and succinate ion increases when diddolved and/or diluted.
it is a physical change because no reaction occurs and there is no new substance. :)
Juicing a lemon is a physical change because the lemon's molecules remain the same even though its physical form changes from solid to liquid. The process of juicing just separates the juice from the pulp without altering the chemical composition of the lemon.
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.
The luster of the lamp is restored
Pancreas release digestive enzymes.

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.
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.
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.
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.
Chemical, physical is generealy changes between the states of matter, although those are not the only physical changes
A mixture is a mix of substances such as blood or juice, physical changes only alter the form of the object not the substance itself.
it is a physical change because no reaction occurs and there is no new substance. :)
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.
Floating is a physical property, and is not a 'change' in any sense.
