$3C+O_2+H_{2}Olongrightarrow{H}_2+3CO$

$C+O_{2}longrightarrowC{O}_2$

$S+H_{2}longrightarrow{H}_{2}S$

$4H+O_2$longrightarrow$2H_{2}O$

$C+2H_{2}longrightarrowC{H}_4$

if you know the

amount of componunts

in Coal :$-$

Carbon $0\mathrm{.}954$

Oxygn longrightarrow$0\mathrm{.}01$

hydragn $0\mathrm{.}022$

sulfur longrightarrow$0\mathrm{.}005$

$N_2$longrightarrow$0\mathrm{.}009$

the $N_2$ is Inert.

find the $\{$:$|n_s|n_c|\frac{n_{CO}}{n_{C{O}_2}}\frac{?}{?}\frac{n_{H_2}}{n_{H_{2}O}}\frac{?}{?}\frac{n_{H_{2}S}}{n_{C{H}_4}})$
