Answer:
Some are storm surge and storm tides, flooding and heavy rainfall
Answer:
The correct answer is B.2.52 mol
Explanation:
The molarity of a solution (M) expresses the number of moles of solute there is in 1 liter of solution. If we have the molarity (M) and the volume in liters (L), we simply multiply M x V to obtain the moles, as follows:
M = 2.21 = 2.21 moles/L
V = 1.14 L
M x V = 2.21 moles/L x 1.14 L = 2.5194 moles ≅ 2.52 moles
Answer:
A bond in which the electronegativity difference between the atoms is between 0.4 and 1.7 is called a polar covalent bond.
A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal.

Answer:
The mass is ![m = 0.0349 \ g](https://tex.z-dn.net/?f=m%20%3D%20%200.0349%20%5C%20g)
Explanation:
From the question we are told that
The Henry's Law constant is ![k = 2.4 *10^{10} M/atm](https://tex.z-dn.net/?f=k%20%3D%202.4%20%2A10%5E%7B10%7D%20M%2Fatm)
The volume of water is ![V = 525 \ ml = 0.525 \ L](https://tex.z-dn.net/?f=V%20%3D%20525%20%5C%20ml%20%3D%200.525%20%5C%20L)
The partial pressure is ![P = 1.90 \ atm](https://tex.z-dn.net/?f=P%20%3D%20%201.90%20%5C%20atm)
The temperature is ![T = 25 ^oC](https://tex.z-dn.net/?f=T%20%20%3D%2025%20%5EoC)
Henry's law is mathematically represented as
Where C is the concentration of sulfur hexafluoride(SP)
substituting value
![C = 1.90 * 2.4*10^{-4}](https://tex.z-dn.net/?f=C%20%3D%201.90%20%2A%202.4%2A10%5E%7B-4%7D)
![C = 4.56*10^{-4} \ M](https://tex.z-dn.net/?f=C%20%3D%204.56%2A10%5E%7B-4%7D%20%5C%20M)
The number of moles of SP is mathematically represented as
![n = C * V](https://tex.z-dn.net/?f=n%20%3D%20C%20%2A%20V)
substituting value
![n = 0.525 * 4.56*10^{-4}](https://tex.z-dn.net/?f=n%20%3D%20%200.525%20%2A%204.56%2A10%5E%7B-4%7D)
![n = 2.39 *10^{-4} \ moles](https://tex.z-dn.net/?f=n%20%3D%20%202.39%20%2A10%5E%7B-4%7D%20%5C%20moles)
The mass of SP that dissolved is
![m = n * Z](https://tex.z-dn.net/?f=m%20%3D%20n%20%2A%20Z)
Where Z is the molar mass of SP which has a constant value of
![Z = 146 g/mole](https://tex.z-dn.net/?f=Z%20%3D%20146%20g%2Fmole)
So
![m = 2.394*10^{-4} * 146](https://tex.z-dn.net/?f=m%20%3D%20%202.394%2A10%5E%7B-4%7D%20%2A%20146)
![m = 0.0349 \ g](https://tex.z-dn.net/?f=m%20%3D%20%200.0349%20%5C%20g)
