Chemistry Honors – Class 30
- Period A – Wednesday, March 12th
- Periods C, D – Tuesday, March 13th
- using “train tracks” is always the preferred way when possible without getting intermediate answers
- be sure and state the overall principle using equations (without numbers ) at the start
- solve without numbers where possible
- show your work logically and in a step-wise manner (make it easy to see your work)
Lab Activity – Boyle’s Law
- Lab handout in the “Laboratory” folder
- Follow the directions for the lab
- record all information in your LNB
- Finish answering lab questions in LNB
- this is NOT a formal lab but you should be clear and concise with all information
FYI – Lab Analysis Questions (WE NEVER “CONNECT THE DOTS”)
- In your lab notebook you should plot a graph of the volume (“Y”) as a function of the pressure (“X”) of the gas. Be sure and take time to make a clear graph that occupies most of the lab page (it should be the only thing on the lab page). A ruler is your best friend.
- Draw the smoothest line possible through the data. You should use a pencil to sketch a line before finalizing your result using a pen in your lab notebook.
- If the result is NOT a straight line, identify a graph that could be plotted that would produce a straight line using this data,
- What type of relationship exists between the pressure and volume of a gas?
- What factors impacted your collecting the data? How did they impact your result?How does this relationship compare to the known relationship as expressed by Boyle’s Law?
