Chemistry tutor near me in Riverside, CA

The Student and Tutor discussed climate change and its relation to chemical reactions. The session focused on stoichiometry, including mole-to-mole and mass-to-mass conversions, with the Student practicing example problems. The Student was assigned a homework problem involving mass-to-mass stoichiometry to complete before the next session.

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.

Nikita and Hannah's organic chemistry lesson centered on conformational isomers. They thoroughly reviewed concepts like Newman projections, eclipsed/staggered conformations, and torsional angles, using ethane, propane, and n-butane as examples. Hannah actively practiced drawing Newman projections for various molecules. They scheduled another lesson to discuss conformations of cyclohexane and address Hannah's questions.

Trusha assisted a student from Syracuse University with a practice exam, covering a comprehensive range of topics. The lesson included de Broglie wavelength, work function and frequency calculations, and essential unit conversions like decigrams to milligrams. They also tackled Heisenberg's uncertainty principle, calculating the number of protons using density and molar mass, and temperature conversions from Kelvin to Fahrenheit. Trusha and the learner plan to meet next on Sunday morning to continue their exam preparation.

Nikita's lesson with Hannah delved into the intricacies of drawing resonance structures in organic chemistry. They covered various systems, including double single positive, double single negative, and double single free radical cases. Hannah actively practiced applying these concepts to different molecules, with Nikita offering expert guidance on electron flow and charge distribution. To solidify her understanding of these chemical principles, Hannah was given practice questions from their discussion to build confidence.

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.
