(A) The thermite reaction involves the reduction of ferric oxide $(Fe_2O_3)$ by aluminium $(Al)$ powder. The balanced chemical equation is: $Fe_2O_3 + 2Al \rightarrow 2Fe + Al_2O_3$ According to the stoichiometry of the reaction,$1$ mole of $Fe_2O_3$ reacts with $2$ moles of $Al$. However,in the thermite mixture used for welding,the ratio by mass is typically $3$ parts of ferric oxide to $1$ part of aluminium powder. Therefore,$X = 3$ and $Y = 1$.

Thermite is a mixture of $X$ parts of ferric oxide and $Y$ parts of aluminium powder. $X, Y$ respectively are
