Correct option:
The correct name for is diphosphorus pentoxide.
Why is called diphosphorus pentoxide?
is commonly known as diphosphorus pentoxide.
Phosphorus pentoxide has an intriguing property in that is actually its empirical formula, whereas
is its actual molecular formula.
However, the name of the chemical was obtained from its empirical formula rather than from its molecular formula. The official name for this substance is diphosphorus pentoxide.
Oxygen-containing binary compounds have "oxide" as their "last name." Phosphorus is the "first name."
We list each atom's numbers below:
The di- and Penta- prefixes are used to indicate the presence of two and five oxygen atoms, respectively, in the molecule.

<u>Answer:</u> The for the given reaction is
<u>Explanation:</u>
For the given chemical reaction:
Half reactions for the given cell follows:
<u>Oxidation half reaction:</u> ( × 2)
<u>Reduction half reaction:</u>
Oxidation reaction occurs at anode and reduction reaction occurs at cathode.
To calculate the of the reaction, we use the equation:
Putting values in above equation, we get:
To calculate standard Gibbs free energy, we use the equation:
Where,
n = number of electrons transferred = 2
F = Faradays constant = 96500 C
= standard cell potential = 0.406 V
Putting values in above equation, we get:
Hence, the for the given reaction is
