Explanation:
That electron is found in the 3d orbital.
ml=-2,-1,0,1,2
n=3
l=2
ml=0
ms=-1/2
Since it must be of opposite spin according to Pauli exclusion principle.

Answer:
17.6% is the percentage error
Explanation:
The percentage error is used to determine accuracy of a measurement (That is, how closely is the measure to the real or theoretical value). The equation is:
|Measure - Real| / Real * 100
In the problem, the measure was 22.7cm³ and real value is 19.3cm³. Solving for percentage error:
|22.7cm³ - 19.3cm³| / 19.3cm³ × 100
<h3>17.6% is the percentage error</h3>
These are the characteristics that apply:
- In a solution taste sour: which is consequence of the H+ concentration.
- Corrode metals: the H+ ion reacts with the metal producing a salt and water
- Produce hydronium ion in solution: as per the Bronsted - Lowry definition an acid is a substance that donates a proton, H+.This proton will react with H2O to form H3O+ (hydronium), as per this scheme:
HA + H2O --> A(-) + H3O(+)
