Question:
A 0.2500-g sample of an Al–Zn alloy reacts with HCl to form hydrogen gas:
The hydrogen produced has a volume of 0.147 L at 25°C and 755 mm Hg. What is the percentage of zinc in the alloy?
Transcribed Image Text:
2 Al(s) + 6 H+ (aq) → 2 Al³+ (aq) + 3 H₂(g) Zn(s) + 2 H+ (aq) → Zn²+ (aq) + H₂(g)
