Answer : The ground-state electronic configuration of oxide ion is,
Explanation :
Electronic configuration : It is defined as the distribution of electrons of atom in an atomic orbital.
<u>Oxygen</u>
The total number electrons in oxygen = 6
The electronic configuration of oxygen is,
<u>Oxide ion</u>
The total number electrons in oxide ion, = 6 + 2 = 8
The charge on O is (-2). So, we are adding 2 electrons.
The electronic configuration of oxide ion is,
Answer:
the maximum volume that can be burned per minute is: 0,895 mL of ethanol.
Explanation:
The combustion of ethanol is:
C₂H₅OH + 3 O₂ → 2 CO₂ + 3 H₂O
With gas law:
PV/RT = n
Where P is pressure (1,00 atm)
V is volume (4,73 L of air per minute)
R is gas constant (0,082 atmL/molK)
T is temperatue(25°C≡298,15K)
And n are moles, replacing:
n = 0,193 moles of air per minute.
These moles of air contain:
0,193 moles air × = <em>0,0406 moles O₂</em>
Thus, the maximum volume that can be burned per minute is:
0,046 moles O₂ = <em>0,895 mL of ethanol per minute</em>
I hope it helps!
