You will only find atoms that were originally present.

(a) $HgandO$
The reaction is $2HgO->2Hg+O_2$

(b) $Ca,C,O, H and Cl$
The reaction is $CaCO_3+2HCl->CaCl_2+CO_2+H_2O$

(c) $C,HandO$
A simple reaction equation cannot be written, as much depends on the heating and the completeness of the burning.
