Answer:
The molar concentration of Fe³⁺ in the unknown solution is 8.01x10⁻⁵M.
Explanation:
When creating a calibration curve in spectrophotometric analysis, you apply Lambert-Beer’s law, which indicates that the absorbance of a compound is directly related to its concentration:
A = E*l*C
Where A stands for absorbance, E is the molar absorption coefficient, l is the path length, and C represents the molar concentration
Using the line equation, you find:
y = 4541.6X + 0.0461
Where Y is the absorbance and X refers to the concentration - we will presume the concentration is expressed in molarity-
Given that the absorbance of the unknown is 0.410:
0.410 = 4541.6X + 0.0461
X = 8.01x10⁻⁵M
The molar concentration of Fe³⁺ in the unknown solution is 8.01x10⁻⁵M.
Answer:The pH measured 10 cm from the most acidic end is 3.42.
Explanation:
The pH at one end = 1The pH at the other end = 13
The chamber length = 13 cm
The change in pH concerning the chamber's length from the acidic end is
Thus, the pH at a distance of 10 cm from the most acidic end is 3.42.
x is greater than or equal to 56Step-by-step explanation: He requires at least 56 additional cans. Hence, x should be a minimum of 56.

Answer:
The forward reaction will keep occurring until all NO or all NO₂ is consumed.
Clarification:
- According to Le Châtelier's principle, when a system at equilibrium experiences a disturbance from an outside source, the system will adjust to counteract this disturbance and restore equilibrium.
- Thus, removing the product (N₂O₃) from the system effectively lowers the product concentration, prompting the reaction to shift forward and generate additional product in order to alleviate the strain caused by the removal of N₂O₃.
- Consequently, the reaction will proceed forward until all of either NO or NO₂ is depleted.
