Problem Consider the following reactions
P + Q ⟶ R + K 2 SO 4 R ⟶ 2 CuI + I 2 Ag + + Q ⟶ S + K + \begin{aligned} P + Q &\longrightarrow R + \text{K}_2\text{SO}_4 \\ R &\longrightarrow 2\text{CuI} + \text{I}_2 \\ \text{Ag}^+ + Q &\longrightarrow S + \text{K}^+ \end{aligned} P + Q R Ag + + Q ⟶ R + K 2 SO 4 ⟶ 2 CuI + I 2 ⟶ S + K + P = CuSO 4 P = \text{CuSO}_4 P = CuSO 4 Q = KI Q = \text{KI} Q = KI R = CuI 2 R = \text{CuI}_2 R = CuI 2 S = K [ AgI 2 ] S = \text{K}[\text{AgI}_2] S = K [ AgI 2 ] Browse the problem library
