The equilibrium concentration of FeSCN2+ is determined using the calibration curve and the absorbance data. The calibration curve relates the absorbance (y-value) to the concentration of FeSCN2+ (x-value). By analyzing the absorbance data obtained from Part B, we can use the calibration curve to calculate the equilibrium concentration of FeSCN2+.

In the first mixture, 1B, the initial concentrations of Fe3+ and SCN- are both 2.00 x 10-3 M. The absorbance measured for this mixture is 0.1694. Using the calibration curve, we find that the equilibrium concentration of FeSCN2+ is 4.0 M.

Similarly, for the other mixtures, we can calculate the equilibrium concentration of FeSCN2+ using the same procedure. In 2B, where the initial concentration of Fe3+ is 3.00 M and SCN- is 4.00 M, the absorbance is 0.2407, resulting in an equilibrium concentration of FeSCN2+ of 3.0 M.

The equilibrium concentrations for the remaining mixtures can be calculated in the same manner, using their respective absorbance values and the calibration curve.

Amount of loss deductible against other income (active and portfolio): $63,000

Suspended rental loss: $42,000

Jiu's total rental loss from the real estate rental activity is $105,000. However, the amount of loss deductible against other income (active and portfolio) is limited. According to the tax rules, Jiu can deduct up to $25,000 of rental losses against her other income.

This amount is known as the rental loss allowance. Therefore, $25,000 of Jiu's rental loss can be offset against her other income, which includes her rent income of $25,000.

The remaining rental loss of $80,000 ($105,000 - $25,000) is considered a suspended rental loss. This suspended loss cannot be deducted against Jiu's other income in the current tax year. Instead, it is carried forward to future tax years, where it can be used to offset rental income or gains from the real estate rental activity.

To summarize: Amount of loss deductible against other income (active and portfolio): $25,000 (rental loss allowance) + $38,000 (remaining active income) = $63,000.

Suspended rental loss: $80,000 - $38,000 (offset against other income) = $42,000.
