Engage with a Chemistry Expert from West Chester University for Interactive Learning Journeys.

Robert provided support to Katie for her biology coursework, delving into topics such as cell theory, the domains of life (Bacteria, Archaea, Eukarya), and the concept of LUCA. Their discussion also touched upon surface tension, the pepper and soap experiment, and the electrical conductivity of the human body. Katie plans to reattempt her quiz questions, and they have arranged a subsequent lesson to tackle scientific notation and unit conversions in preparation for an upcoming lab quiz.

During a recent lesson, Robert helped an individual from Cape Coral review electron configurations, isotopes, and ions in preparation for a chemistry exam. The learner practiced problems related to electron configurations, determining the number of subatomic particles in isotopes and ions, and using the equations E=hv and c=λv to solve for energy, frequency, and wavelength. They also discussed strategies for memorizing formulas and managing test anxiety.

Robert assisted Isha with a comprehensive chemistry lesson, focusing on practice questions related to mass spectrometry, molecular formula determination, and stoichiometry. Isha actively worked through problems from practice tests, specifically addressing calculations for average atomic mass, determining molecular formulas, and converting between grams, moles, and atoms. Together, they reviewed the correct problem-solving approaches and underscored the importance of using Avogadro's number when dealing with molecules.

Robert guided Cassy through key organic chemistry concepts, specifically focusing on cyclohexane chair conformations and Newman projections. Cassy actively practiced drawing chair flips and correctly assigning axial/equatorial positions. Robert also provided an initial look at chirality, introducing R/S configurations and diastereomers as a preview of future topics. They have arranged their next lesson for Wednesday at 9 AM.

During a recent lesson, Robert tutored Ajay in chemistry, specifically preparing him for an upcoming exam. Their focus included a thorough review of formulas for wavelength, frequency, and energy calculations. Ajay actively engaged in practicing unit conversions and problem-solving techniques, utilizing equations like c=λν and E=hν. To reinforce the concepts, Robert assigned additional practice problems and arranged a follow-up lesson to delve into electron configurations and other related topics.

An individual assisted a learner from Ontario with chemical nomenclature, covering ionic and molecular compounds, polyatomic ions, and ionization energy. The learner practiced naming compounds and determining their formulas, focusing on balancing charges and using the periodic table. They plan to meet again on Wednesday to continue their review.
