Answer: Option (d) is the correct answer.

Explanation:

It is known that gases at low pressure and high temperature behave ideally as they do not have any intermolecular forces of attraction between them.

Whereas it temperature is decreases or lowered then molecules of the gas will come closer to each other.

As a result, there will be increase in the intermolecular forces of attraction and very less or no repulsion will take place between the molecules. Hence, gas will behave non-ideally at low temperature.

Thus, we can conclude that it is true for a gas under conditions of very low temperature that  PV/nRT = 1, because particles are unable to overcome intermolecular attractions.

If a molecule with a central atom that has five regions of electron density has exactly one lone pair of electrons. What will it
Hoochie [10]

The molecular geometry of a molecule with a core atom that has five areas of electron density and precisely one lone pair of electrons is called a disphenoidal or seesaw molecular geometry.

What is meant by disphenoidal or seesaw molecular geometry?

  • Four bonds are made to an atom in the center of a disphenoidal or seesaw-shaped molecular structure, which has overall C2v structural symmetry. The fact that it resembles a playground seesaw is how it got the moniker "seesaw." Tetrahedral or, less frequently, square planar geometry is produced when four bonds to a center atom are present.
  • The core atom of a molecule with a steric number of 5 and bonds to 4 additional elements and 1 lone pair is said to be in the seesaw geometry.

One mole of silver has a mass of 107.9 grams. Approximately how many atoms of silver are present in one mole of silver?
irga5000 [103]

Answer:

The number of atoms in 1 mole silver is also 6.022 *10^23 atoms.

Option C is correct.

Explanation:

Step 1: Data given

Mass of 1 mole silver = 107.9 grams

Step 2: Calculate the number of atoms in 1 mole of silver

To calculate the number of atoms in 1 mole, we multiply the number of Avogadro by the number of moles

Number of atoms = 1 mol * 6.022 *10^23 atoms/ mol

Number of atoms = 6.022 * 10^23 atoms

Since the number of Avogadro says there are 6.022 * 10^23 atoms per 1 mole. The number of atoms in 1 mole silver is also 6.022 *10^23 atoms.

Option C is correct.
