AP Chemistry Concepts and Applications

In this AP Chemistry virtual lesson, Michael Farabaugh from Albemarle High School provides an overview of the AP exam details, including the date and format. He explains how students can use the AP Classroom for practice, highlighting the availability of optional practice problems and free response questions. The lesson includes a detailed walkthrough of solving AP Chemistry free response questions, emphasizing the importance of understanding concepts like the ideal gas law, combustion reactions, and rate laws. The session concludes with an announcement of a special guest, Dr. Abbott, a Nobel Prize winner, who will join the next lesson.
