Diamond is unaffected by conc. acids, but graphite reacts with hot conc.$\mathrm{H}\mathrm{N}{\mathrm{O}}_3$forming mellitic acid${\mathrm{C}}_6(\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}{)}_6$

$\mathrm{C}\mathrm{O}$is toxic because it forms a complex with hemoglobin in the blood

${\mathrm{C}}_3{\mathrm{O}}_2$, carbon suboxide, is a foul-smelling gas

$\mathrm{C}\mathrm{O}\mathrm{C}{\mathrm{l}}_2$is called tear gas.
