A sample of $10\mathrm{.}5g$ of $F{e}_2{O}_3$ reacts with $11\mathrm{.}7$gCO to yield $Fe$ and $C{O}_2.$ The balanced chemical equation is

$F{e}_2{O}_3(s)+3CO(g)2Fe(s)+3C{O}_2(g)$

Which substance is the limiting reactant?

$F{e}_2{O}_3$

$Fe$

$CO$

$C{O}_2$

What is the theoretical yield of Fe$?$
