Teaching and response guide
- Begin with: What is the H₂:O₂ mole ratio?
- Connect the response to: With enough oxygen, how many moles of H₂O form from 4 moles of H₂?
- Ask students to apply the idea: How many moles of H₂O can that mixture form?
Watch for: Accepting an answer without checking whether it uses the material and satisfies the requested relationship or criteria.
Check the answer criteria for each task. A supported explanation may have more than one acceptable response. These activities offer evidence to discuss; completing a sheet alone does not establish mastery.
