Question

The Goldschmidt thermite process uses Aluminium to reduce transition metal oxides. Consider the balanced chemical equation for the reduction of Manganese(II,III) oxide ($Mn_3O_4$) by Aluminium powder: $a Mn_3O_4 + b Al \rightarrow c Al_2O_3 + d Mn$. When balanced with the smallest whole numbers, what is the sum of the stoichiometric coefficients of the products $(c + d)$?
