Answer:

= 3.01 x 10²³ atoms of gold (Au)

Explanation:

1 mole of any substance => 1 Avogadro's Number of particles = 6.02 x 10²³ particles.

∴ for 5 moles of gold atoms => 5 moles x 6.02 x 10²³ atoms/mole

= 3.01 x 10²³ atoms of gold (Au)

Direct electron transfer from a singlet reduced species to a triplet oxidizing species is quantum-mechanically forbidden
posledela

Direct electron transfer from a a singlet reduced species to a triplet oxidizing species is quantum-mechanically forbidden.

<h3><u>Transfer from singlet to triplet:</u></h3>
  • Either an excited singlet state or an excited triplet state will occur when an electron in a molecule with a singlet ground state is stimulated (through radiation absorption) to a higher energy level.
  • All electron spins in a molecule electronic state known as a singlet are coupled.
  • In other words, the ground state electron and the stimulated electron's spin are still coupled (a pair of electrons in the same energy level must have opposite spins, per the Pauli exclusion principle).
  • The excited electron and ground state electron are parallel in a triplet state because they are no longer coupled (same spin).
  • It is less likely that a triplet state would arise when the molecule absorbs radiation since excitation to a triplet state necessitates an additional "forbidden" spin transfer.

b. Determine the molecular formula of a molecule with an empirical formula NH2and a molar mass of 32 g/mol.
VladimirAG [237]
I'm taking this lesson now, so imma help u ( if u need anything else ask me)

so given Molar mass= 32 g/mol
molar mass= (empirical formula) n
32 = (14x1 + 2x1) n
32 = 16 n , so n= 2
so, molecular formula= N2H4
