$Fe _{3} O _{4}( s )+4 CO ( g ) \rightarrow 3 Fe ( l )+4 CO _{2}( g )$
when $4.640 \,kg$ of $Fe _{3} O _{4}$ and $2.520 \,kg$ of $CO$ are allowed to react then the amount of iron (in $g$ ) produced is $....$
[Given : Molar Atomic mass $\left( g\, mol ^{-1}\right): Fe =56$
Molar Atomic mass $\left( g \,mol ^{-1}\right): 0=16$
Molar Atomic mass $\left( g\, mol ^{-1}\right):= C =12$
${N_2}(g) + {O_2}(g) \rightleftharpoons 2NO(g)$
${N_2}{O_4}(g) \rightleftharpoons 2N{O_2}(g)$
${N_2}(g) + 3{H_2}(g) \rightleftharpoons 2N{H_3}(g)$
