Westkost [7]

Answer:

2

Step-by-step explanation:

A. Moles before mixing

<em>Beaker I: </em>

Moles of H⁺ = 0.100 L × 0.03 mol/1 L

                   = 3 × 10⁻³ mol

<em>Beaker II: </em>

Beaker II is basic, because [H⁺] < 10⁻⁷ mol·L⁻¹.

        H⁺][OH⁻] = 1 × 10⁻¹⁴   Divide each side by [H⁺]

             [OH⁻] = (1 × 10⁻¹⁴)/[H⁺]

             [OH⁻] = (1 × 10⁻¹⁴)/(1 × 10⁻¹²)

             [OH⁻] = 0.01 mol·L⁻¹

Moles of OH⁻ = 0.100 L × 0.01 mol/1 L

                      = 1 × 10⁻³ mol

B. Moles after mixing

                 H⁺    +    OH⁻   ⟶ H₂O

I/mol:      3 × 10⁻³   1 × 10⁻³

C/mol:   -1 × 10⁻³  -1 × 10⁻³

E/mol:    2 × 10⁻³          0

You have more moles of acid than base, so the base will be completely neutralized when you mix the solutions.

You will end up with 2 × 10⁻³ mol of H⁺ in 200 mL of solution.


C. pH

 [H⁺] = (2 × 10⁻³ mol)/(0.200 L)

        = 1 × 10⁻² mol·L⁻¹

 pH = -log[H⁺ ]

       = -log(1 × 10⁻²)

       = 2

Which of the following can be best explained by temporary dipole moments?
Tju [1.3M]

Answer:

B. This explains how two noble gases' molecules can have an attractive force between them.

C. This explains why long hydrocarbon chains have relatively high boiling points.

Explanation:

Temporary dipole moments are weak intermolecular force of attraction between two or more compounds. They are the weakest of intermolecular forces. They form when non-polar molecules becomes polar due to the constant motion of their electrons. This may lead to an uneven charge distribution at an instant.

When this occurs, the molecule has a  temporary dipole. The dipole can induce neighboring molecules to be distorted and form dipoles as well.

  • Two noble gases can exhibit this bonding attraction usually when at low temperature. The temporary dipole cause a temporary charge separation and can lead to attraction.
  • Long hydrocarbons of long chains also exhibits this bonding which can cause a rise in their boiling point.
  • Ammonia and nitrogen gas will exhibit hydrogen bonding, a strong dipole - dipole attraction.
  • Hydrogen fluoride and methanol has hydrogen bonds likewise dimethyl either and acetone.

Pls help I’m stuck on this part
Verizon [17]

Answer:

As you begin your trip down the hill you increase your speed resulting in a transformation from potential energy to kinetic energy.

Explanation:

At the top of the mountain, you have potential energy. But as you start moving down the mountain, your speed increases and have a lot of kinetic energy.
