Well, honey, when you mix lemon juice with limestone, you're causing a chemical reaction that breaks down the calcium carbonate in the limestone. This reaction forms calcium citrate, carbon dioxide, and water, which is definitely a chemical change. So, yes, adding lemon juice to limestone is a chemical change, no ifs, ands, or buts about it.
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 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.
Fermenting fruit juice is a chemical change because it involves the conversion of sugars in the juice into alcohol and carbon dioxide by yeast through a biochemical process. This results in the formation of new substances with different properties from the original juice.
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 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

No!

It is a chemical change because it can not be reversed

When lemon juice is mixed with vinegar, it does not change color significantly. Lemon juice is already acidic and adding vinegar, which is also acidic, will not produce a significant color change.
