The open spaces in water's crystal structure make it possible for <span>aquatic life to exist at the north pole.

It is good to know that, at the north pole, when the temperature drops below zero, only the top layer of the water freezes. Underneath this freezing layer, water remains in its liquid form, thus, allowing marine life to exist. As for oxygen, it is also trapped underneath the ice layer. </span>

8) (When allyl alcohol dissolves in water, the particles of allyl alcohol
labwork [276]

Hydrogen  bonding interaction occurs between  the oxygen atom of water and  the hydrogen atom of allyl alcohol that is covalently bonded to the oxygen atom.

We must recall that allyl alcohol is a molecular substance. Molecular substances do not dissociate into ions in water. As such particles of allyl alcohol remain intact when dissolved in water.

Hydrogen bonding occurs when hydrogen is bonded to an electronegative atom such as oxygen. In allyl alcohol, hydrogen  bonding interaction occurs between  the hydrogen atom of water and the oxygen atom of allyl alcohol.

Also,  hydrogen  bonding interaction occurs between  the oxygen atom of water and  the hydrogen atom of allyl alcohol that is covalently bonded to the oxygen atom.

Amphetamine (c9h13n) is a weak base with a pkb of 4.2. calculate the ph of a solution containing an amphetamine concentration of
soldier1979 [14.2K]

Answer:

pH = 10.505

Explanation:

Molar mass of Amphetamine ( C9H13N) = 135 g/mol

Given that the concentration of Amphetamine = 225 mg/L

mass of Amphetamine in one Liter = \frac{225}{ 1000} = 0.225 g

Number of moles of Amphetamine in one liter =\frac {0.225 g} { 135g/mol}

= 0.001667 mol

∴ molarity = 0.0017 M

              C₉H₁₃N          +        H₂O -------->       C₉H₁₃NH⁺  +      OH⁻

I(M)         0.001667   M                                                  0                 0

C(M)            -x                                                                  x                 x

E(M)         0.001667 - x                                                   x                 x

Pkb = -log Kb = 4.2

∴ Kb = 6.309 x 10⁻⁵

Kb = 6.309 x 10⁻⁵

Equilibrium constant  = [C₉H₁₃NH⁺][OH⁻]/ [C₉H₁₃N]

6.309 x 10⁻⁵  = x² / 0.001667-x

where 0.001667 -x ≅ 0.001667

Then;

x² = 6.309 x 10⁻⁵  × 0.001667

x² =  1.0517103 × 10⁻⁷

x = \sqrt {1.0517103 * 10^{-7}

x = 0.00032 M

x = [OH-] = 0.00032 M

∴ pOH = -log [OH-]

pOH = -log (0.00032)

pOH =3.495

pH = 14 - 3.495

= 10.505
