WATER INVESTIGATION LAB
Physical Description:
Before:
- Submerged tubes filled entirely with water
After:
- Submerged tubes had less water and
- Clear gas
Quantitative Measurements:
Before:
- No gas in tubes
After:
- Tube w/ Red wire: 1.5 in of gas
- Tube w/ Back wire: 3 in of gas
- Mass of battery stays the same
Particle Diagram:
Chemical Symbols/Equation:
Before:
2H2O
After:
2H2 + O2
Total:
2H2O ----> 2H2 + O2
Description:
In this lab we separated the water in two tubes into oxygen and hydrogen using a battery. We recorded the amount of gas in the tubes and made a ratio of it, to show the number of atoms in each molecule before the reaction. With this we made a equation that showed the molecules present and the changing bonds. Then we made a particle diagram that did the same thing, as well as demonstrate the pattern that the molecules made.
