Hello!
To determine the Kb of gallic acid is actually very simple.
The
dissociation reaction of Gallic Acid (HGal) is the following:
HGal+H₂O ⇄ H₃O⁺ + Gal⁻The equation for converting from Ka to Kb is the following:

So, the Kb is
2,19*10⁻¹²Have a nice day!
3Na2S2O3 + AgBr ------>Na5[Ag(S2O3) 3] +NaBr
from equation 3 mol 1 mol
given x mol 0.10 mol
x= (3*0.10)/1=0.30 mol Na2S2O3
Answer: 0.30 mol Na2S2O3
Answer:
The final pressure is approximately 0.78 atm
Explanation:
The original temperature of the gas, T₁ = 263.0 K
The final temperature of the gas, T₂ = 298.0 K
The original volume of the gas, V₁ = 24.0 liters
The final volume of the gas, V₂ = 35.0 liters
The original pressure of the gas, P₁ = 1.00 atm
Let P₂ represent the final pressure, we get;



∴ The final pressure P₂ ≈ 0.78 atm.
