Top 10 Chemistry tutors near St. Petersburg, FL

The Student and Tutor worked through several homework problems related to the energy of photons, the electromagnetic spectrum, and the photoelectric effect. They focused on applying relevant formulas like E=hV, c=lambda*V, and the Bohr model equation, along with practicing unit conversions and calculator usage. The Student has seven remaining problems to complete and was encouraged to reach out if further assistance is needed.

The Student and Tutor reviewed Lewis structures, focusing on the octet rule, calculating valence electrons, and the step-by-step process of drawing structures including those with double/triple bonds and expanded octets. They also began discussing molecular geometries, differentiating between electron pair and molecular shapes. The Tutor offered to upload notes for the Student to use for their upcoming quiz.

The Student and Tutor reviewed an introduction to carbohydrates, covering their definitions, classifications (aldoses/ketoses, monosaccharides/oligosaccharides/polysaccharides), structures, biological functions, and stereochemistry including enantiomers, diastereomers, and epimers. They also touched upon hemiacetal and hemiketal formation, with plans to continue with carbohydrate cyclization in the next session.

The Student and Tutor reviewed fundamental chemistry concepts, including Lewis structures and different types of chemical bonds (ionic, covalent, and coordinate covalent bonds). The session introduced and applied VSEPR theory to predict molecular shapes, with the Student working through examples. They also briefly re-examined a complex stoichiometry problem from a previous class and agreed to continue practicing similar problems in the next session.

Student and Tutor reviewed core biochemistry concepts, starting with the distinction between polar and non-polar substances. They then extensively compared the structures and functions of different carbohydrate forms—cellulose, glycogen, and starch—focusing on their glycosidic linkages and branching. The session also covered amphipathic lipids and their behavior in water, alongside the definition of a spontaneous chemical process. The Student reported a successful quiz result and indicated plans for test preparation in the next session.

Student and Tutor continued their discussion on intermolecular forces, focusing on van der Waals interactions and their biochemical significance. They then moved to an in-depth review of pH, acid-base equilibrium, and methods for calculating pH and pKa values. The upcoming sessions will cover titration curves and Henderson's equation, followed by an introduction to general chemistry, specifically thermochemistry.
