Elevate Your Biology Learning with a Creative Tutor from West Chester Univ. Embrace Innovative Teaching!

The Student and Tutor reviewed nomenclature, formula mass calculations, percent composition, and the octet rule in preparation for a chemistry unit test. The Student practiced naming compounds, writing formulas, and calculating molar masses. They also discussed strategies for remembering ion charges and naming acids, and planned to review additional practice problems in the next session.

The student reviewed aromaticity concepts and practiced reaction mechanisms, including Friedel-Crafts alkylation and acylation, and elimination-addition reactions. The student worked through a problem set and identified areas for further review before an exam. They also discussed the retake policy for a previous exam and planned to connect after the upcoming fall break to schedule future sessions.

Robert assisted Shae with understanding aromatic chemistry, focusing on activators, deactivators, and directing effects in electrophilic aromatic substitution. They worked through practice problems, identifying reaction mechanisms and predicting products. Shae will practice additional problems and ask her professor about a discrepancy in the textbook regarding acylation versus alkylation reactions.

During a recent chemistry lesson, Robert assisted Katie with her lab assignment, specifically addressing the critical concepts of accuracy, precision, and significant figures in experimental data. They meticulously reviewed calculations, pinpointing errors in Katie's approach, particularly concerning the determination of water's density. Katie plans to refine her measurements for the lab and has arranged for a follow-up lesson next week.

Robert and Cassy dedicated their recent organic chemistry lesson to tackling a variety of complex problems. Their work encompassed drawing stereoisomers, calculating enantiomeric excess, determining optical activity, and converting bond-line structures into Fisher projections. They also thoroughly reviewed R/S configurations, the concept of chirality, and the properties of meso compounds. Cassy plans to submit her homework, and they've arranged to meet again next week to continue their studies in organic chemistry.

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.
