Answer:
Sink
Explanation:
For a substance to float in water, it must be less dense than water. The density of water is 1 g/cm^3. To find the density of the substance, we can do mass/volume, which in this case is 25g/7cm^3. We see that , so the substance would sink.
The lone pair of electrons in Theobromine are shown in RED color in attached figure.
Details:
In chemistry there are two types of electrons.
i) Bonding Pair Electrons:
These are those electrons which are being shared and are involved in making bonds. They are also called as sharing electrons. In given structure all the solid bonds either single or double are made up of bonding pair electrons.
ii) Lone Pair / Non-Bonding Pair Electrons:
Those electrons which doesn't take part in bonding and are not shared between atoms. In given structure the lone pair of electrons are found only on nitrogen atoms (single lone pair) and oxygen atoms (two lone pair of electrons) respectively.
Hybridization of Nitrogen Atoms;
N₁ = Sp²
N₂ = Sp³
N₃ = Sp³
N₄ = Sp³
Hybridization of Oxygen Atoms;
O₁ = Sp²
O₂ = Sp²
