SECTION A: PHYSICAL CHEMISTRY

ii) Calculate the mass of aluminum required to completely react with 7.98g of iron (II) oxide, $\text{Fe}_2\text{O}_3$.
Reaction: $\text{Fe}_2\text{O}_3 + 2\text{Al} \rightarrow \text{Al}_2\text{O}_3 + 2\text{Fe}$
Atomic masses: Fe = 55.85 g/mol, O = 16.00 g/mol, Al = 26.98 g/mol

Step 1: Calculate the molar mass of $\text{Fe}_2\text{O
