Nitric acid does not form the anhydride but dinitrogen penta oxide is theoretical anhydride of nitric acid.
2HNO3 = N2O5 + H2O

No. From the Wikipedia article on nitrogen pentoxide:
N2O5 was first reported by Deville in 1840, who prepared it by treating AgNO3 with Cl2.
Therefore, nitrogen pentoxide is the anhydride of nitric acid.
Nitiric acid
Trifluoromethanesulfonic anhydride = (CF3SO2)2O
The balanced equation for the reaction between salicylic acid and acetic anhydride to form aspirin (acetylsalicylic acid) is: salicylic acid + acetic anhydride → aspirin + acetic acid.
Your question has the names right in it. Maybe it's the chemical formulas you want. In that case, salicylic acid is C7H6O3 and acetic anhydride is C4H6O3.
The anhydride of chlorous acid is dichlorine hexoxide, with the chemical formula Cl2O6.
An anhydride is not an acid and not a base.

Sulfur dioxide is the anhydride of sulfurous acid, H2SO3; the acid minus this oxide is water.
No, it does not
The anhydride of chlorous acid is dichlorine hexoxide, with the chemical formula Cl2O6.
No, formic acid does not form an anhydride. Anhydrides are formed by the condensation of two carboxylic acid molecules with the loss of a water molecule. Formic acid (HCOOH) is the simplest carboxylic acid and does not contain a reactive group necessary for anhydride formation.
nitric acid is heterogeneous.
The reaction between salicylic acid and acetic anhydride involves the substitution of a hydroxyl group in salicylic acid with an acetyl group from acetic anhydride. This reaction is catalyzed by an acid, typically sulfuric acid, and results in the formation of aspirin and acetic acid as byproducts.
The IUPAC name for nitric acid is "nitric acid." But its Periodic name is HNO3
