False

Explanation:

Dispersion forces are the weakest of all intermolecular forces. They are appropriately called London dispersion forces or LDF.

  • They are the weakest form of intermolecular forces.
  • Crystal lattice forces are the strongest intermolecular forces that holds crystalline substances together.
  • London dispersion forces are weak attractions found between non-polar to polar molecules and noble gases.
  • The attraction is as a result of non-polar substances becoming polar in nature.
  • This is due to the constant motion of electrons which leads to uneven distribution of electrons.

35.0 mL of 12.0 M HCl is added to enough water to have a final volume of 1.20 L. What is the molarity of the final solution?
creativ13 [48]
<h3>Answer:</h3>

0.35 M

<h3>Explanation:</h3>

<u>We are given;</u>

  • Initial volume as 35.0 mL or 0.035 L
  • Initial molarity as 12.0 M
  • Final volume is 1.20 L

We are required to determine the final molarity of the solution;

  • Dilution involves adding solvent to a solution to make it more dilute which reduces the concentration and increases the solvent while maintaining solute constant.
  • Using dilution formula we can determine the final molarity.

M1V1 = M2V2

  • Rearranging the formula;

M2 = M1V1 ÷ V2

     = (12.0 M × 0.035 L) ÷ 1.2 L

      = 0.35 M

Thus, the final concentration of the solution is 0.35 M

List all orbitals from 1s through 5s according to increasing energy for multielectron atoms. rank orbitals from smallest to larg
GaryK [48]

Answer:

1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s

Explanation:

You can predict the order of orbital energies by constructing a diagram as shown below.

Follow the arrows to get the orbitals in order of increasing energy.

The order is

1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p < 5s

A 10.0 mL sample of HNO3 was exactly neutralized by 13.5 mL of 1.0 M KOH. What is the molarity of the HNO3? Use the titrations f
Kruka [31]

Answer: Thus molarity of HNO_3 is 1.35 M

Explanation:

To calculate the volume of acid, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is HNO_3

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is KOH.

We are given:

n_1=1\\M_1=?M\\V_1=10.0mL\\n_2=1\\M_2=1.0M\\V_2=13.5mL

Putting values in above equation, we get:

1\times M_1\times 10.0=1\times 1.0\times 13.5\\\\M_1=1.35M

Thus molarity of HNO_3 is 1.35 M
