In my Chemistry II class, my teacher did an experiment involving dropping solid Sodium metal into a beaker filled with distilled water, which caused an explosion that shattered the beaker. After the experiment, he gave us this problem to answer, which counts as four test grades:
The density of Sodium metal is 0.97g/cm³. If Mr. Oliver used a rectangular prism of Sodium metal 2.50 cm x 1.00 cm x 0.50 cm, how many liters of Hydrogen and Oxygen gas at 500°C and 1.00 atm would be produced when placed in ¾ of a liter of water? Would the Hydrogen and Oxygen be in a perfect stoichiometric mixture?
He also gave us these balanced chemical equations which he said would help us solve this problem:
1. 2Na + 2H2O 2NaOH + H2
2. 4Na + O2 2Na2O
3. 2Na2O Na2O2 + 2Na
4. Na2O2 +2H2O2 H2O2 + 2NaOH
5. H2O2 2H2O + O2
6. 2H2 + O2 2H2O
Side reaction = Na2O + H2O 2NaOH
This is due on Monday, and if anybody could please help me with this, I would REALLY appreciate it!
