Answer:
Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory.
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 .
Answer is because

if you divide 279 / 49 it = 5.69, which you would just round up to 5.7
Answer:
0.028578 km
Explanation:
The following data were obtained from the question:
Length of whale (in mm) = 28578 mm
Length of whale (in km) =?
We can convert 28578 mm to km by doing the following:
Recall:
1 mm = 1×10¯⁶ Km
Therefore,
28578 mm = 28578 mm × 1×10¯⁶ Km / 1 mm
28578 mm = 0.028578 km
Thus, 28578 mm is equivalent to 0.028578 km
The length of whale (in km) = 0.028578 km
