Announcements: Be prepared to film or photograph your fuelling process
Warm-ups: Show me what mass of Zn you will weigh out and what mass of MnO2 you need.
Zn + HCl ↓ ZnCl2 + H2
H2O2 + MnO2 ↓ MnO + O2 + H2O
Use 20 mL of HCl to generate hydrogen
Use 25 mL of H2O2 to generate oxygen Homework: Type and annotate all the math/chemistry
