Answer 2

When lemon is squeezed onto the rock, a gas is liberated. This gas turned the lime water milky. This confirms that Carbon dioxide is present in the rock.

This is because insoluble calcium carbonate that is CaCO3 is formed. CaCO3 is insoluble in water. So it produces a white precipitate and forms milky lime water.
