The total number of electrons in p orbitals in a silver atom is 18.

The position of silver (Ag) in the fifth row of the periodic table, the 11th column of the periodic table, the 9th column of the transition metal, or the d block, determines the electron configuration for silver (Ag). The atomic number of silver is 47. Consequently, the final electron configuration for silver must be:

The energy of a photon is hv. Where h is plank's constant and v be the frequency. The frequency of a photon with an energy of 3.75 × 10⁻²¹ J is 5.66 × 10¹² Hz.

Frequency of a wave is the number of wave cycles per unit time. It is the inverse of the time period. Thus, has a unit of s⁻¹ which is equivalent to Hz.

Frequency of a wave is directly proportional to the energy.

The energy of a photon = hv

h is the planck constant = 6.62 × 10⁻34 J.s

Given the energy of a photon = 3.75 × 10⁻²¹ J

Thus, frequency = energy/planck's constant

= 3.75 × 10⁻²¹ J/ 6.62 × 10⁻34 J.s

= 5.66 × 10¹² Hz.

Therefore, the frequency of the photon is 5.66 × 10¹² Hz.

The ratio of the atoms of the iridium and the platinum is; 8.86 : 1. Option B

We know that the atom is the smallest particle of the substances that can be able to take part in a chemical reaction. We know that in the platinum and the iridium, we both have atoms in the substances and now we would want to get the number of atoms that is in each of the elements.

Number of moles of iridium = 100g/192 g/mol = 0.52 moles

Number of moles of platinum = 900g/195 g/mol= 4.6 moles

Number of atoms in the iridium atom = 0.52 moles * 6.02 * 10^23 atoms

= 1.2 * 10^23 atoms

Number of atoms of platinum = 4.6 moles * 6.02 * 10^23 atoms

Explanation:

The value of [H+] can be calculated using the concentration of the HCl solution and the balanced chemical equation for the dissociation of HCl in water:

HCl (aq) + H2O (l) → H3O+ (aq) + Cl- (aq)

The concentration of HCl is 3.65 g / (36.5 g/mol) = 0.1 M

The concentration of H+ ions in the solution can be calculated using the concentration of HCl and the stoichiometry of the dissociation reaction:

[H+] = 0.1 M x (1 mol H+ / 1 mol HCl) = 0.1 M

To show that [OH-] is 1.00 x 10-12 M, we can use the relationship between [H+] and [OH-] in aqueous solutions, which is given by the ion product constant for water (Kw):

Kw = [H+] [OH-] = 1.00 x 10-14

Substituting the value of [H+] that we calculated above, we can solve for [OH-]:

[OH-] = Kw / [H+] = (1.00 x 10-14) / (0.1 M) = 1.00 x 10-12 M

Therefore, the concentration of OH- ions in the solution is 1.00 x 10-12 M.

Among all the statements, statement A is incorrect that is the n = 2 energy level has no d orbitals.

The angular momentum quantum number (l)- The orbital form is determined by this integer with the values l = 0, 1, 2,...,  n - 1.

Because of this, an orbital with n = 1 can only have one value of l, l = 0, while an orbital with n = 2 can have both l = 0 and l = 1. The orbital's overall dimensions and energy are determined by the primary quantum number. The orbital's form is determined by the l value. Subshells are formed by orbitals with the same value of l. Additionally, the angular momentum of an electron in this orbital increases with the angular momentum quantum number.

The d orbitals are the orbitals with l = 2. Then, the value of l is -
