Yes. It's a cute demonstration for school science fairs, but using the citric acid from lemon juice in a battery isn't really practical in most applications.
How a lemon lights up a LED light is lemon juice has acid (a.k.a acidic juice) so when u connect zinc and copper to the lemon since they are conductors energy will flow from the acid to the copper or zinc and then it will flow through wires and the energy will be transformed into light energy and will be used by the LED light.
Yes. Basically the lemon contains citric acid which acts as the electrolyte in this case.
Lemon has Citric acid in it.
Not much. Of course, the exact amount of energy varies, depending on the sound volume.
A lemon contains Citric Acid.
Lemon juice contains an acid (but by itself it is not an acid, because it is not a pure compound): citric acid makes lemon juice acidic.
Lemon juice contains citric acid.
No. Lemon juice contains citric acid, which is a weak acid.
The acid lets the electricty flow throw the lemon

Yes, lemon juice is a weak acid due to its citric acid content. When lemon juice is added to water, it releases hydrogen ions, making it acidic. However, compared to strong acids like hydrochloric acid, lemon juice is considered weak.
Lemon contains citric acid, which gives it its sour taste.
