(A) The thermite reaction involves the reduction of ferric oxide $(Fe_2O_3)$ by aluminium $(Al)$ powder. The balanced chemical equation is: $Fe_2O_3 + 2Al \rightarrow 2Fe + Al_2O_3$ From the stoichiometry of the reaction, $1$ mole of $Fe_2O_3$ reacts with $2$ moles of $Al$. However, the question refers to the mass ratio or parts by weight commonly used in the thermite process. In the standard thermite mixture, $3$ parts of ferric oxide $(Fe_2O_3)$ are mixed with $1$ part of aluminium powder $(Al)$ by weight. 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
