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

The Student and Tutor worked through several chemistry practice questions covering topics like ion identification, physical versus chemical changes, and the Periodic Law. They then conducted a detailed review of significant figures, including their rules for identification and application in calculations. The session concluded with a discussion and practice of Parts Per Million (PPM) and Parts Per Billion (PPB) calculations, with the Tutor providing additional practice materials.

The student and tutor reviewed a chemistry exam, focusing on concepts such as water's solvent properties, solubility rules, Bronsted-Lowry theory, and solution concentration calculations. The tutor provided detailed feedback on the student's answers, highlighting areas where the instructor's grading was overly strict regarding units and the presentation of work.

The Student and Tutor focused on Organic Chemistry concepts, specifically SN1, SN2, E1, and E2 reactions, and factors influencing their outcomes. They worked through practice exam problems, analyzing substrate types, reagent classifications, solvent effects, and carbocation stability. The Student also cross-referenced their lecture notes and an answer key with the Tutor to clarify discrepancies and deepen understanding.

Student and Tutor reviewed multiple chemistry concepts related to gases, including interpreting gas expansion scenarios, understanding the behavior of gases in flexible containers, and clarifying the Law of Combining Volumes. They defined absolute zero and molar volume, and extensively related the Kinetic Molecular Theory to the Ideal Gas Law, Avogadro's Law, and Dalton's Law of Partial Pressures. The session concluded with a discussion of exam preparation strategies and scheduling the next meeting for the following Friday.

The student and tutor reviewed organic chemistry reactions, including hydroboration bromination, the conversion of alkenes to alkynes, and the Diels-Alder reaction. They practiced identifying reaction mechanisms, predicting products, and understanding stereochemical outcomes, with a focus on cyclic and substituted reactants. The tutor also briefly touched upon catalytic hydrogenation and reactions involving conjugated dienes.

The student and tutor reviewed the chemistry of alkynes, focusing on electrophilic addition reactions, reductions, and methods for forming and using acetylide ions. They also covered alkyne synthesis and tautomerization processes, with plans for the student to review provided screenshots of tautomerization mechanisms.
