Explanation:
If we compare its solubility products without any calculation then, Magnesium hydroxide is more soluble than compound A and C. Magnesium hydroxide is less soluble than compound D.
- The solubility product of magnesium hydroxide and zinc carbonate is same so it is not possible to determine whether it is more or less soluble than compound B
The bond is highly polar is the scientific claim about the bond in the molecular compound HF is most likely to be true.
The term polar means that there is separation of charges, the bonds will be the more polar the greater the difference in electronegativity between the bonded atoms.
- In hydrogen fluoride, for example, F is more electronegative than H because its nucleus, with 9 positive charges, attracts e-shares with H more strongly than the nucleus of H, with only one positive charge.
- Therefore, the e- shared by covalence will be closer to F than to H and the molecule forms a permanent dipole.
Therefore, we can conclude that the bond is highly polar is the scientific claim about the bond in the molecular compound HF is most likely to be true.

There are 4 oxygens in the compound
<u>Answer: </u>The concentration of 
in the solution is 
<u>Explanation:</u>
pH is defined as the negative logarithm of hydrogen ion concentration present in the solution.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
.....(1)
We are given:
pH of solution = 2.5
Putting values in equation 1, we get:
![2.5=-\log [H^+]](https://tex.z-dn.net/?f=2.5%3D-%5Clog%20%5BH%5E%2B%5D)
![[H^+]=10^{-2.5}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-2.5%7D)
![[H^+]=3.16\times 10^{-3}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D3.16%5Ctimes%2010%5E%7B-3%7DM)
Hence, the concentration of in the solution is
