Solution:
- (b) $S+O_2 \longrightarrow SO_2$ (burns with blue light)
$4 Na+O_2 \longrightarrow 2 NaO$
(burns with yellow light)
$ \begin{aligned} & P_4+3 O_2 \longrightarrow P_4 O_6 \\ & P_4+5 O_2 \longrightarrow P_4 O _{10} \\ & Cl+O_2 \longrightarrow \text{ No reaction } \end{aligned} $
Chlorine does not react directly with oxygen.
