To wrap up your year of general chemistry, have lab groups compete in a tot wire chemical vapor deposition (HWCVD) competition. With their foundation in chemical nomenclature, stoichiometry, and gas laws, each group completes several tasks to earn points. Tasks include building and diagramming molecular models, calculating molar masses, researching HWCDV on silane, and preparing a presentation. Both the student handouts and teacher's resources are user-friendly. This lesson is top-notch!
