![**Text for Educational Website:**
A mixture is prepared by combining 11.18 mL of 2.31 x 10⁻³ M Fe(NO₃)₃ with 10.00 mL of 1.89 x 10⁻³ M KSCN. The solution turns red due to the formation of FeSCN²⁺. The absorbance is measured and, using a calibration plot, the [FeSCN²⁺] at equilibrium is found to be 1.68 x 10⁻⁴ M.
**Complete the following ICE table:**
\[
\begin{array}{|c|c|c|c|c|}
\hline
& \text{Fe}^{3+} & + & \text{SCN}^- & \rightleftharpoons \text{FeSCN}^{2+} \\
\hline
\text{initial (M)} & \text{(A)} & & \text{(B)} & \text{(C)} \\
\hline
\text{change (M)} & \text{(D)} & & \text{(E)} & \text{(F)} \\
\hline
\text{equilibrium (M)} & \text{(G)} & & \text{(H)} & \text{(I)} \\

**Explanation of Diagrams:**
The image contains an ICE table used to calculate equilibrium concentrations. "ICE" stands for Initial, Change, and Equilibrium, representing the concentrations of species involved in a reaction at different stages. The table consists of data to be filled out, with some given values, and seeks the calculation of the equilibrium constant \( K_c \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0c365b9c-2713-4371-a77a-f9bb68b19349%2F54fbce00-0cd9-43ee-aa1d-92136b0998b7%2F5audvyq_processed.png&w=3840&q=75)
