Yes, fermenting fruit juice is a chemical change.
It is a physical change.

No, you just create a mixture with more components.
It's a chemical change because the lemon and water cannot be separated by physical means. If it were a physical change, then the lemons and water would not be dissolved.
Because a physical change affects things like looks and shape. When a piece of lemon turns the tea cloudy, it doesn't affect it's chemical composition.
Burning is a chemical change.

Chemical The acid in the lemon clouds the water and the elements combine.

it is a chemical change that makes a physical change take place
This is a chemical change. The hydrogen rich acid from the lemon juice suppresses the slightly negative and highly pigmented ions being produced by certain poly phenol compounds - commonly grouped as tannins. The neutralization of the pigmented ions by the acid in the lemon juice causes the observed lightening of the liquid.
physical reaction
== == Washing Soda+lemon juice=co2+other products == == A chemical reaction has taken place between the reactants, washing soda and lemon juice. Carbon dioxide is one of the products. the chemical change cannot be reversed. So it is a irreversible change.
Physical change- it can be undone by evaporating the water.
