PH=5.57
pH+pOH=14
5.57 + pOH=14
pOH = 14-5.57= 8.43
pOH = - log [OH⁻]
-pOH= log [OH⁻]
![[OH^{-}] = 10^{-pOH}= 10^{-8.43}= 3.72*10^{-9} [OH^{-}]= 3.72*10^{-9}](https://tex.z-dn.net/?f=%5BOH%5E%7B-%7D%5D%20%3D%2010%5E%7B-pOH%7D%3D%2010%5E%7B-8.43%7D%3D%203.72%2A10%5E%7B-9%7D%0A%0A%20%5BOH%5E%7B-%7D%5D%3D%203.72%2A10%5E%7B-9%7D)

Answer:
XY → X + Y general reaction represents a decomposition reaction where a molecule is “broken” in two separate molecules
Explanation:
In a double-displacement reaction two molecules will exchange atoms or group of atoms, and it should look like this:
XY + AB → XA + YB
In a combustion reaction molecules are reacting with oxygen generating oxides.
XY + O → XO + YO
In a single-displacement reaction an atom or a group of atoms in a molecule are replaced by other atoms, and it should look like this:
XY + A → XA + Y
