To determine the oxidation state to which selenium is converted during the reaction between `SeO2` and `CrSO4`, we can follow these steps: ### Step 1: Calculate the number of moles of `SeO2` and `CrSO4` 1. **Calculate moles of `SeO2`:** - Volume of `SeO2` = 12.53 cm³ = 12.53 mL - Molarity of `SeO2` = 0.51 M - Moles of `SeO2` = Molarity × Volume (in L) \[ ...
