Answer is: 12 <span>moles of water will be produced.
</span>Balanced chemical reaction: N₂H₄ + O₂ → N₂ + 2H₂O.
n(N₂H₄) = 6 mol.
From balanced chemical reaction: n(N₂H₄) : n(H₂O) = 1 : 2.
n(H₂O) = 2 · n(N₂H₄).
n(H₂O) = 2 · 6 mol.
n(H₂O) = 12 mol.
n - amount of substance.

The pka of hf is 3.2 determine the pkb of hf?
Julli [10]

Well, first we must remember that

pK_{a}+pK_{b}=14

This is because

K_{a}*K_{b}=10^{-14}

-log(K_{a}*K_{b})=-log(10^{-14})\\-logK_{a}+-logK_{b}=-log(10^{-14})\\pK_{a}+pK_{b}=14

So then

pK_{b}=14-pK_{a}=14-3.2=1.8
