Lesson 8: Act Science Mastery

Under certain conditions, hydrogen and oxygen gas can be mixed together to form H20. Students performed the following experiment to study the formation of H2O. 

The chemistry students fitted a gas syringe with a sparking device, then filled the syringe with different levels of H, and O2 gas. The syringe plunger was then locked in place and the gases were sparked. The resulting reaction caused water to form inside the syringe. Finally, the plunger was released, and the gas in the syringe was allowed to adjust temperature and pressure. The final the gas was recorded and analyzed to its composition. Table 1 shows the experiment with varying initial levels H2. 

The row labeled Trail 1 has a 0 in the Final 0₂ column.

The highest number in the Final O₂ column is 30. This is in Trail 3 row.

The difference between the initial and final H₂ volume in the Trail 5 row os 50 - 30=20. This is greater than the difference in any other row
