MCQ
Identify the correct set which can only act as oxidants
- A$NO_3^-,\, SO_3, Na$
- ✓$Fe^{+3}, \,NO_3^-,\, SO_3$
- C$I^-,\, Na$
- D$I^-,\, NO_3^ -$
Central atom has maximum oxidation state, so they will only act as oxidising agent.

$C + {O_2} \to C{O_2};\,\Delta H = - 394\,kJ\,mo{l^{ - 1}}$
$2CO + {O_2} \to 2C{O_2};\,\Delta H = - 569\,kJ\,mo{l^{ - 1}}$ The heat of formation of $1\,mol$ of carbon monoxide is thus .....$kJ\,mo{l^{ - 1}}$
$4C{a_5}{(P{O_4})_3}F + 18Si{O_2} + 30C \to 3{P_4} + 2Ca{F_2} + 18CaSi{O_3} + 30CO$
