Answer: NO
You cannot not trap a polarizable atom in a purely electrostatic field.
Answer:
0,171 M NaCl and 0,168 m NaCl
Explanation:
Molarity (M) is an unit of chemical concentration that relates moles of solute per liters of solution and molality (m) is another unit of chemical concentration that relates moles of solute per kg of solution.
For a solution of 10g/L of NaCl the molarity is:
10g/L NaCl×
= 0,17 moles/L of NaCl≡ 0,171 M NaCl
For molality you can know that in 1 L you have 0,17 moles of NaCl.
The kg of solution are:
0,010 kg of NaCl (solute) + 1 kg of solvent (Water, 1L of water is 1 kg) = 1,01 kg of solution.
Thus, molality of 10 g/L NaCl solution is:
= 0,168 m NaCl

1) Answer is: the hydrogen ion concentration is 1·10⁻¹ mol/L.
[OH⁻] = 1·10⁻¹³<span> mol/L, equilibrium concentration of hydroxide anion.
</span>[H⁺] is the concentration<span> of hydrogen ions.
</span>[OH⁻] · [H⁺] = 10⁻¹⁴ mol²/L², ionicproduct of water on room temperature.
[H⁺] = 10⁻¹⁴ mol²/L² ÷ 1·10⁻¹³ mol/L.
[H⁺] = 10⁻¹ mol/L = 0,1 mol/L.
2) pH = -log[H⁺], <span>approximately </span><span>the negative of the base 10 </span>logarithm<span> of the </span>molar concentration of hydrogen ions
pH = -log(10⁻¹ mol/L).
pH = 1.
This solution is acid, because pH value (potential of hydrogen) is less than seven. If pH is greater than seven, slotion is base and if pH is equal seven, solution is neutral.
Ethers have a much lower boiling point than their isomeric alcohols because ether have not hydrogen bond that why ethers have lower boiling point .
Ethers will not have a hydrogen atom attached to the oxygen atom as alcohols do. Because ether molecules can not form intermolecular hydrogen bonds, their boiling points are much shorter than those of alcohol with such a comparable mass.
Owing to the combination of intermolecular H-bonding in alcohols though not in ethers, alcohols possess higher boiling temperatures than isomeric ethers.
Therefore, ethers have a much lower boiling point than their isomeric alcohols because ether have not hydrogen bond that why ethers have lower boiling point .
