Vedclass · Answer

(A) The thermite reaction is the reduction of metal oxides by aluminium powder. The balanced chemical equation for the reaction between ferric oxide $(Fe_2O_3)$ and aluminium $(Al)$ is: $Fe_2O_3 + 2Al \rightarrow 2Fe + Al_2O_3$ From the stoichiometry of the balanced equation,$1$ mole of $Fe_2O_3$ reacts with $2$ moles of $Al$. However,in the context of the standard thermite mixture used for welding,it is typically prepared as a mixture of $3$ parts of ferric oxide $(Fe_2O_3)$ and $1$ part of aluminium powder $(Al)$ by mass. Therefore,$X = 3$ and $Y = 1$.

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