Answer 1

lemon reduce the heat all around it to make it cool

Answer 2

When lemon juice falls on a shahbad tile, effervescence is observed, and a spot is formed on the area where the juice has fallen.

• Shahbad tile is nothing but limestone. It is made of calcium carbonate (CaCO₃).

• Lemon juice contains citric acid (C₆H₈O₇).

• When lemon juice falls on a shahbad tile, the citric acid in the juice reacts with calcium carbonate in the tile.

• Immediately, carbon dioxide gas is out with a fizz in the form of effervescence, and a spot of calcium citrate is formed on the tile.

• The reaction can be represented as follows :

2C₆H₈O₇ + 3CaCO₃  →  Ca(C₆H₅O₇)₂ + 3CO₂ + 3H₂O
