The OCR of the image is: --- 1 SO2 + HNO3 = NO2 + H2SO ② Fellz + Cu = Fella + bullz ③ I₂ + Br2 + H2O = HIO3 + HBr 2 ---

Решение:

1. \( \text{SO}_2 + \text{HNO}_3 \rightarrow \text{NO}_2 + \text{H}_2\text{SO}_4 \)
2. \( \text{FeCl}_3 + \text{Cu} \rightarrow \text{FeCl}_2 + \text{CuCl}_2 \)
3. \( \text{I}_2 + \text{Br}_2 + \text{H}_2\text{O} \rightarrow \text{HIO}_3 + \text{HBr} \)

Ответ: 1. SO₂ + HNO₃ → NO₂ + H₂SO₄; 2. FeCl₃ + Cu → FeCl₂ + CuCl₂; 3. I₂ + Br₂ + H₂O → HIO₃ + HBr.
