Hey there!
HC2H3O2(aq) + H2O(l) → H3O⁺(aq) + C2H3O2⁻(aq)

acid base acid base
If we consider the only forward reaction H3O⁺is the conjugate acid of the base H2O
. For reversse reaction CH3COOH is the conjugate acid of the base CH3COO⁻.
Hope this helps!

Answer:
It doesn't matter which chloride
Explanation:
Because Carboxylic acids reacts with any of these inorganic chlorides such as PCl3, PCl5 and SOCl2 to form acid chloride as the major product, then the acid chloride further reacts to form acid anhydride
Answer:
V₂ = 19.3 L
Explanation:
Given data:
Initial volume = 29.3 L
Initial pressure = standard = 1 atm
Initial temperature = standard = 273 K
Final temperature = -23°C (-23+273 = 250K)
Final volume = ?
Final pressure = 1.39 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 1 atm × 29.3 L × 250 K / 273 K × 1.39 atm
V₂ = 7325 atm .L. K / 379.47 K.atm
V₂ = 19.3 L
