A tanker containing a mixture of hydrocarbon$-$based mud with an amount of $2500$ kg is sent to a

scheduled waste incinerator. The mud contains $15$ wt$\%$ of $2,4-$dichlorophenol ; MW $=$

$163\mathrm{.}00),10$ wt$.\%$ of $1,3-$dinitrobenzene $(C_6{H}_4{N}_2{O}_4$;$MW=168\mathrm{.}12),5wt\%$ of dichlorophenylarsine

$(C_6{H}_{5}AsC{l}_2$;$MW=221\mathrm{.}93),20wt.\%$ of sand and impurities and the remaining are water. Answer the

following questions. $($Given molecular weight: $C{O}_2=44\mathrm{.}01$;$H_{2}O=18\mathrm{.}02$;$HCl=36\mathrm{.}46$; Air $=29\mathrm{.}00$;

$A{s}_2{O}_3=197\mathrm{.}84,N{O}_2=46\mathrm{.}00.$

a$)$ Determine the amount of all components in the hydrocarbon$-$based mud and write the possible

reactions involved in the incineration process. Due to high volatility, the metal element in the

dichlorophenylarsine is converted to metal oxide.
