The property of water which is described in the lines above is <u>cohesion.
</u>It refers to the fact that water molecules stick to other water molecules, i. e. to themselves, as opposed to sticking to another material, which happens with adhesion. Water and capillaries don't have any connection.<u>

Answer:

  3.0×10⁻¹³ M

Explanation:

The solubility product Ksp is the product of the concentrations of the ions involved. This relation can be used to find the solubility of interest.

<h3>Equation</h3>

The power of each concentration in the equation for Ksp is the coefficient of the species in the balanced equation.

  Ksp = [Al₃⁺³]×[OH⁻]³

<h3>Solving for [Al₃⁺³]</h3>

The initial concentration [OH⁻] is that in water, 10⁻⁷ M. The reaction equation tells us there are 3 OH ions for each Al₃ ion. If x is the concentration [Al₃⁺³], then the reaction increases the concentration [OH⁻] by 3x.

This means the solubility product equation is ...

  Ksp = x(10⁻⁷ +3x)³

For the given Ksp = 3×10⁻³⁴, we can estimate the value of x will be less than 10⁻⁸. This means the sum will be dominated by the 10⁻⁷ term, and we can figure x from ...

  3.0×10⁻³⁴ = x(10⁻⁷)³

Then x = [Al₃⁺³] will be ...

  [\text{Al}_3^{\,+3}]=\dfrac{3.0\times10^{-34}}{10^{-21}}\approx \boxed{3.0\times10^{-13}\qquad\text{moles per liter}}

We note this value is significantly less than 10⁻⁷, so our assumption that it could be neglected in the original Ksp equation is substantiated.

<em>Additional comment</em>

The attachment shows the solution of the 4th-degree Ksp equation in x. The only positive real root (on the bottom line) rounds to 3.0×10^-13.

True or False?<br><br> Weak bases dissociate<br> completely into (OH)- and<br> metal cations.
ki77a [65]

Answer:

False

Explanation:

When weak bases dissociate, an equilibrium is established rather than dissociating 100%. So OH- and metal ions are partially ionized.

What are all of the pressure conversions ? like torr atm kPa
olasank [31]

Answer:

Explanation:

Torr:

Torr is the measure of pressure produced by one mmHg equal to the 1/760 of standard pressure used to the pressure of vacuum system.

Millimeter mercury mmHg:

It is the manometric pressure unit. It is defined as, the pressure exerted by column of mercury one millimeter high. it is represented by mmHg.

Torr to mmHg conversion:

Both are equal to each other.

1 torr = 1 mmHg

Torr to atm:

Torr is converted into atm by dividing the torr value 760.

mmHg to atm.

mmHg is converted into atm by dividing the torr value 760.

Kilopascal:

The kilopascal is the unit of pressure. It is represented by KPa.

it is the pressure generated by 10 g mass of substance on area of 1 cm².

There are 1000 pascal in one kilopasca.

one atm = 101.325 KPa

one atm = 101325 Pa

atm can be converted into KPa by multiplying the given atm value with 101.325.

For example:

4.1 atm × 101.325  kpa/ 1 atm

415.432 atm. kpa / 1atm

415.432 kpa

Kpa to atm:

415.432 kpa/101.325  kpa × 1 atm

4.1 × 1 atm

4.1 atm
