Hello!
This question can be solved using the
Henderson-Hasselbach equation, but first we need to know the value of pKa
pKa= -log(Ka)= -log(7,1*10⁻⁶)=5,15
Now, we apply the equation:
So, the pH of this solution would be
4,98
Have a nice day!
Answer:
16. What is the wavelength of a 1.32 x 10-6 eV wave?
ν = E /ν = h = 1.32 x 10-6
eV x 1.602 x 10-19
J = 3.191 331 38 x 10+8 s-1
6.626 2 x 10-34J-s 1 eV
λ = c/ν = ν = 3.00 x 108
m/ν = s = 3.00 x 108
m x 1
3.191 331 38 x 10+8 s-1
s 3.191 331 38 x 10+8 s-1
= 0.940 m
Explanation:
The answer is 0.940 m That is unless i messed something up-

Answer:
The water molecules slow down, stronger attractions form between them, and the molecules are pulled closer together.
Explanation:
In solids the packing of the particles is closer and tighter thus increasing the intermolecular attraction. This makes solids rigid with a definite shape, size and volume. On the other hand in liquids the packing of the particles is loose thus decreasing the intermolecular attraction. This makes liquids able to flow, and takes the shape and volume of the container in which they are placed.
