Answer:
I
Explanation:
The complete question can be seen in the image attached.
We need to understand what is actually going on here. In the first step that yields product A, the sodamide in liquid ammonia attacks the alkyne and abstracts the acidic hydrogen of the alkyne. The second step is a nucleophilic attack of the C6H5C≡C^- on the alkyl halide to yield product B (C6H5C≡C-CH3CH2).
Partial reduction of B using the Lindlar catalyst leads to syn addition of hydrogen to yield structure I as the product C.
You can predict it by measuring the weight of the spherical object and measuring the liquid (mL) and subtracting finding the volume
Hot/ warm air is less dense than cold/cool air. Therefore warm/ hot air rises and cool/cold air falls in the atmosphere to create convection currents. The hot air balloon also uses this concept to fly. The air in the balloon is heated by the inbuilt flamer and when the air rises in temperatures (in comparison to ambient air temperatures) it becomes less dense and begins to rise. This raises the balloon into the atmosphere.

Paleontology is the answer
