Answer:

  • <u><em>1.12 liters</em></u>

Explanation:

<u>Calculating number of moles</u>

  • Molar mass of O₂ = 32 g
  • n = Given weight / Molar mass
  • n = 1.6/32
  • n = 0.05 moles

<u>At STP</u>

  • One mole of O₂ occupies 22.4 L
  • Therefore, 0.05 moles will occupy :
  • 22.4 L x 0.05 = <u><em>1.12 L</em></u>

1mol of any gas at STP contains 22.4L

moles of O_2

  • Given mass/molar mass
  • 1.6/32
  • 0.05mol

Now

Volume of O_2:-

  • 0.05(22.4)
  • 1.120L

When electrons are filling energy levels, the lowest energy sublevels are occupied first. This is ____________.
Nimfa-mama [501]

When electrons are filling energy levels, the lowest energy sublevels are occupied first. This is Hund's rule.

Hund's rules state that:

Every orbital in a sublevel has to be singularly occupied before any other orbital is able to be doubly occupied.

All of the electrons in single occupied orbitals have to have the same spin to maximize the total spin.

nata0808 [166]

Answer:

NH₄⁺

H₂PO₄⁻

H₃O⁺

Explanation:

  • An ion is an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
  • Ion may be positively charged "cation" or negatively charged "anion".
  • Neutral molecule has a net charge of zero.

<em>So, the species that are ions are: </em>
