Solution:

Since, $ \text{CHC}{{\text{l}}_{\text{3}}} $ is a surjection. Therefore, A is the range of $ \text{CC}{{\text{l}}_{\text{4}}} $ . The domain of $ \text{C}\text{N} $ is R. Let $ \text{S}0 $ Then. $ \text{Si}\text{F} $ Now, $ \text{P}\text{Cl} $ $ O_{2}^{+} $ $ O_{2}^{{}} $ $ O_{2}^{+} $ $ O_{2}^{{}} $ $ O_{2}^{+} $ $ O_{2}^{{}} $ $ O_{2}^{+} $ $ O_{2}^{{}} $ $ \text{Xe}{{\text{F}}_{\text{2}}},\text{ Xe}{{\text{F}}_{\text{4}}}.\text{ Xe}{{\text{O}}_{\text{3}}} $ $ \text{Xe}{{\text{F}}_{\text{2}}},\text{ Xe}{{\text{O}}_{\text{3}}},\text{Xe}{{\text{F}}_{6}}\text{ } $ $ N{{H}_{3}},S{{O}_{2}},{{H}_{2}}O $ $ \text{KMn}{{O}_{\text{4}}} $ Now, $ {{C}_{2}}O_{4}^{2-} $ us real. $ C{{O}_{2}} $ $ \text{KMn}{{O}_{\text{4}}} $ $ \left( {{\text{H}}_{\text{2}}}{{\text{C}}_{\text{2}}}{{\text{O}}_{\text{4}}}-\text{2}{{\text{H}}_{\text{2}}}\text{O} \right) $ $ -\text{ 3268 kJ mo}{{\text{l}}^{\text{-1}}} $ So. range of $ -\text{3264}\,\text{kJmo}{{\text{r}}^{\text{-1}}} $ is [0, 1). Hence, A = [0,1)
