Lol. It is now a solution and not really inseparable, so your only logical option would be to throw it away and try again.
Given :
0.00072 M solution of 
at 
.
To Find :
The concentration of 
and pOH .
Solution :
1 mole of gives 2 moles of ions .
So , 0.00072 M mole of gives :
![[OH^-]=2 \times 0.00072\ M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D2%20%5Ctimes%200.00072%5C%20M)
![[OH^-]=0.00144\ M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D0.00144%5C%20M)
![[OH^-]=1.44\times 10^{-3}\ M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D1.44%5Ctimes%2010%5E%7B-3%7D%5C%20M)
Now , pOH is given by :
![pOH=-log[OH^-]\\\\pOH=-log[1.44\times 10^{-3}]\\\\pOH=2.84](https://tex.z-dn.net/?f=pOH%3D-log%5BOH%5E-%5D%5C%5C%5C%5CpOH%3D-log%5B1.44%5Ctimes%2010%5E%7B-3%7D%5D%5C%5C%5C%5CpOH%3D2.84)
Hence , this is the required solution .
A physical property does not change the substance.
Solubility would be the answer since all of the rest are changing the substance. They all deal with bonds except solubility.
Answer: D. Solubility
Cola-flavored soda: 2. 6 -Acidic
cranberry juice: 2. 9 -Acidic
dish soap: 7. 3 -Basic
pickle juice: 5. 5 -Acidic
seawater: 8. 0 -Basic
lye soap: 13. 0. -Basic
<h3>What is pH?</h3>
pH value tells us about the acidity and basicity of any solution. pH means potential hydrogen.
The pH scale is counted from 0 to 14 in which 7 is neutral and the value of pure water.
Below 7 are all acids and the above 7 are all basic.
Thus, all acidic substances are Cola-flavored soda: 2. 6, pickle juice: 5. 5, cranberry juice: 2. 9.

Answer:
Chilling the hydrogen peroxide solution
Explanation:
The MnO₂ is acting as a catalyst.
Chilling the hydrogen peroxide solution reduces the average kinetic energy of the H₂O₂ molecules.
Fewer of them will have enough kinetic energy to overcome the activation energy of the reaction. The rate will decrease.
A is wrong. Using a larger amount of solution does not increase the number of H₂O₂ molecules that can reach the surface of the catalyst per second. There is no effect on the rate.
B is wrong. Increasing the mass of the cube increases its surface area. More molecules of H₂O₂ can reach the surface of the catalyst per second. The rate increases.
D is wrong. Smashing the cube into pieces vastly increases the surface area, so the rate increases
