Teaching guide, sample answers and curriculum references

Before you begin

Read or listen to the model and identify what the task asks before responding.

How to use this worksheet

  1. How many complete reaction batches can occur?
  2. How many hydrogen molecules remain?
  3. Check hydrogen and oxygen atom counts for one batch.

A common mistake to discuss

Reactants have four H atoms and two O atoms; two water molecules contain the same counts.

What to practice next

Create a different example that preserves the learning goal, and explain how you would check it.
