Answer:

Ion-dipole attraction force pulls I^{-} into solution

Explanation:

I^{-} is an anion and water molecule is dipolar due to polarization of bonded electron towards more electronegative oxygen atom.

Hence, when KI is added in water, water molecule attracts K^{+} ions through its negatively charged polarized end and I^{-} through its positively charged polarized end.

At equilibrium, this ion-dipole attraction force overcome the ionic interaction present between K^{+} and I^{-}.

Hence KI become soluble into water.

Determine the boiling point of a solution that contains 70.6 g of naphthalene (C10H8, molar mass = 128.16 g/mol) dissolved in 72
MissTica

Answer:

Boiling point of the solution is 82.3°C

Explanation:

Boiling point elevation is defined as the increasing of a boiling point of a substance by the addition of a solute. The formula is:

ΔT = K×m×i

<em>Where ΔT is change in temperature (Final T - 80.1°C), K is boiling point elevation constant (2.53°C/m), m is molality of the solution (moles of naphthalene / kg of benzene) and i is Van't Hoff factor (1 for Naphthalene)</em>

Moles of 70.6g of naphthalene are:

70.6g × (1mol / 128.16g) = 0.5509 moles

Kg of 722mL of benzene are:

722mL × (0.877g / mL) × (1kg / 1000g) = 0.633kg of benzene

Replacing in boiling point elevation formula:

(T - 80.1°C) = 2.53°C/m×(0.5509mol / 0.633kg)×1

T - 80.1°C = 2.2°C

T = 80.1°C + 2.2°C

T = 82.3°C

<h3>Boiling point of the solution is 82.3°C</h3>

If I have 2mol NaOH in 3L solution, what is the molarity of my solution
Artist 52 [7]
Molarity is defined as the number of moles dissolved in 1 L of solution .2 mol of NaOH has been dissolved in a volume of 3 L.
we need to then find the number of NaOH moles dissolved in 1 L.
Molarity = number of moles / volume in L
Molarity = 2 mol / 3 L = 0.67 mol/L
Therefore molarity of NaOH - 0.67 M

Answer:

Answer: There are 9 ways to make a single base mismatch, 27 ways to make a two base pair mismatch and, again, 27 ways to make a three base pair mismatch (and only 1 way to do it correctly).

The redundancy built into the genetic code and other energetic considerations raise this number considerably.
