Lewis structures refers to the diagrams used to signify the bonding between the atoms of a molecule and the lone pair of electrons, which may prevail in the molecule. These structures are drawn on the basis of the formal charge of each atom within the ion or molecule.
The formal charge refers to the charge assigned to an atom in a molecule, which all the electrons are shared equivalently amongst the atoms regardless of its electronegativity.
The rule for formal charge calculation is,
Formal charge = no of valency shell electron - 1/2 of the no of shared pair electron - no of lone pair electron.
So, in this case, the formal charge of P = 5 - 1/2 (10) - 0 = 0
The valence shell of P have 5 electrons. The total 5 bond is there in the given composition, so total 10 bonding electron, and there is no lone pair of electron on P atom. So, formal charge of P is 0.

Answer:
Ventilators are provided in the rooms at the top of the roofs because if the air inside the room gets hot, the hot air rises up and flows through these ventilators and thus cool air remains at bottom. Thus ventilators maintain conventional currents to keep the air fresh in the room.
Explanation:
1.) A compound is a thing that is composed of two or more (separate) elements.
2.) A compound cannot be separated easily, while its properties differ from where it originates from. It also is formed from chemical reactions.
3.) A pure substance, also known as chemical substance, is a material with constant composition and consistant properties.
4.) If a substance is not a pure substance, then it is an impure substance.
