2. Practice Test #2 (20 minutes)

2. Activity

Challenge

• You will be launching a 2L bottle powered by the reaction reaction between hydrogen gas, H2, and oxygen gas, O2, to produce water vapor. Upon ignition, the reaction produces a larger amount of heat quickly causing rapid expansion of the gases contained in the bottle and thus propulsion of the bottle into the air.

Questions

1. Write and balance the reaction that will occur in your bottle.
2. You will filling your bottle with oxygen first and then hydrogen through the bottom of the bottle. Make a mark on your bottle to indicate when you will stop adding oxygen and begin fill with hydrogen.
3. Why is it important for you to add oxygen before adding hydrogen?
4. If you add too much oxygen, what will you observe upon ignition. Too little oxygen?

3. Homework

• Complete both practice finals
