Vedclass · Answer

(B) The chemical reactions are:$Fe_2O_3 + 3CO ightarrow 2Fe + 3CO_2$$2C + O_2 ightarrow 2CO$From the stoichiometry,$1 \ mol$ of $Fe_2O_3$ requires $3 \ mol$ of $CO$.To produce $3 \ mol$ of $CO$,we need $1.5 \ mol$ of $O_2$ (since $2 \ mol$ of $CO$ require $1 \ mol$ of $O_2$).Moles of $Fe_2O_3 = \frac{1.6 	imes 10^3 \ g}{160 \ g/mol} = 10 \ mol$.Moles of $CO$ required $= 3 	imes 10 = 30 \ mol$.Moles of $O_2$ required $= \frac{30}{2} = 15 \ mol$.Mass of $O_2 = 15 \ mol 	imes 32 \ g/mol = 480 \ g$.

What is the mass of oxygen in $g$ required to produce enough $CO$ for the complete reduction of $1.6 \ kg$ of $Fe_2O_3$ (molar mass $= 160 \ g/mol$)?
