Which reaction vessel will produce the most gas (will fill the balloon the most)?

Why do you think that?

After viewing the demo:

Which reaction vessel produced the most gas (filled the balloon the most)?

What do you think caused this to happen?

phet Simulation:

Visualizing Stoichiometry In the simulation, select Molecules and select Make water to explore the reaction H2+O2→H2O

  1. How many molecules of H2 react with 1 molecule of O2?

  2. How many molecules of H2O are produced?

  3. What happens when you change the number of H2 or O2 molecules?

  4. How does this affect the amount of H2O produced?

phet Simulation:

Visualizing Stoichiometry In the simulation, select Molecules and select Make Ammonia to explore the reaction N2+H2→NH3.

  1. What is the mole ratio of N2​ to H2​?

  2. What is the mole ratio of N2​ to NH3​?

  3. How does increasing the number of H2 molecules affect the amount of NH3​ produced?

  4. What happens if you double the number of N2​ molecules?
