SUMMARY
The percent composition of an aluminium-zinc alloy can be calculated by analyzing the reaction of the alloy with excess hydrochloric acid (HCl). In this case, a 1.00 g sample produced 0.0610 g of hydrogen gas (H2). The balanced chemical equation must account for the individual reactions of aluminium (Al) and zinc (Zn) with HCl, rather than treating the alloy as a single compound. The alloy's formula should be represented in a general form, as it is a physical mixture of Al and Zn.
