Top 10 Chemistry tutors near Fresno, CA

The Student and Tutor reviewed general chemistry concepts related to equilibrium and thermodynamics. They practiced calculating the equilibrium constant (K) and Gibbs free energy (ΔG) using various methods, including ΔG from formation energies, ΔG from enthalpy and entropy, and relating ΔG to the reaction quotient (Q). The session concluded with an in-depth look at the temperature dependence of K, solving problems using the Van 't Hoff equation, and planning to start acids and bases in the next session.

The Student and Tutor reviewed key General Chemistry concepts, including formula mass, molecular mass, the mole concept, Avogadro's number, percent composition, and empirical and molecular formulas. The Student actively practiced various calculations related to these topics. For follow-up, the next session is scheduled for tomorrow at 7 PM CST to cover molarity and solution concentrations, and a unit exam (practice questions) covering the first three chapters was planned for future review.

The Student and Tutor reviewed calculations for molarity and molality. They then learned about and practiced determining empirical and molecular formulas from elemental percentages and molar masses, including a multi-element example. A revision session focusing on practice problems for all covered topics, including isotopes, was planned for the next class.

The student and tutor reviewed addition reactions in organic chemistry, including the mechanisms, Markovnikov's rule, and anti-Markovnikov addition. They practiced predicting products for various addition reactions and began discussing ozonolysis as a method for cleaving double bonds, with plans to cover more complex addition reactions and mechanisms in the next session.

Student and Tutor focused on organic chemistry topics, including SN1 and SN2 reaction mechanisms, isomerism, chirality, and resonance. They practiced classifying alkyl halides, predicting reaction rates, determining R/S configurations, and drawing resonance structures for carbocations. A follow-up session was scheduled to delve deeper into the role of nucleophile strength in these reactions.

The Student and Tutor reviewed advanced organic chemistry concepts, including drawing resonance hybrids, identifying localized and delocalized lone pairs, and understanding their impact on molecular geometry and hybridization. They also covered Bronsted-Lowry acid-base definitions, pKa calculations, and factors affecting acid/base strength and equilibrium positions. The Tutor will send the Student a link to the textbook, and the Student indicated a break from classes.
