What is the correct name for the compound, P2O5?
2 answers:
Answer : The correct name for the compound, is, Diphosphorous pentoxide.
Explanation :
is a covalent compound because in this compound the sharing of electrons takes place between phosphorous and oxygen. Both the elements are non-metals. Hence, it will form covalent bond.
The naming of covalent compound is given by:
- The less electronegative element is written first.
- The more electronegative element is written second. Then a suffix is added with it. The suffix added is '-ide'.
- If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on.
Hence, the correct name for the compound, is, Diphosphorous pentoxide.

Answer: A) More base is likely required to reach the endpoint for the diprotic acid than for the monoprotic acid under these conditions
Explanation:
The monoprotic acid (HA) has a valency of 1 and diprotic acid has a valency of 2.
As the concentration and volume of the diprotic acid and the monoprotic acids are equal.
The neutralization reaction for monoprotic acid is:
The neutralization reaction for diprotic acid is:
Thus more number of moles of base are required for neutralization of diprotic acid and thus the volume required will be more as concentration and volume of the diprotic acid and the monoprotic acids are equal.
