Dynamic Chemistry educator fostering interactive learning through practical exercises and visual demonstrations.

The Student and Tutor reviewed calorimetry, including calculations of heat, calibration factors, and enthalpy changes in solution. They also discussed energy transformations and efficiency. The Student was assigned practice problems from the textbook, and the next session will cover redox reactions and past paper questions related to the topics discussed.

The Tutor and Student practiced problems on limiting and excess reagents, stoichiometry, and thermochemistry, including calculations of heat energy and heat of combustion. The Student worked through examples involving mass, volume, and temperature changes. The next session will continue with solutions to calorimetry problems.

The Tutor and Student reviewed stoichiometry calculations, focusing on mass-mass, mass-volume, and volume-volume relationships in combustion reactions. The Student practiced calculations involving energy release and greenhouse gas production. The Student was assigned practice problems on stoichiometry for the next session, with a plan to discuss limiting and excess reagents.

The Student and Tutor discussed fuels, combustion, energy consumption, and the environmental impact of fossil fuels. They also explored alternative renewable fuels like biogas, bioethanol, and biodiesel, including the concept of carbon neutrality. The session concluded with plans to reschedule the next class to a weekday and a discussion of the Student's recent chemistry results.

The session covered intermolecular forces, polarity, and electronegativity, with the Student practicing identifying polar and non-polar molecules. The relationship between molecular structure, intermolecular forces, and physical properties was examined. The Student was assigned review questions from chapters six and seven in preparation for the next session.

The Student and Tutor reviewed covalent bonding, molecular shapes, and the valence shell electron pair repulsion (VSEPR) theory. They discussed the properties of non-metallic elements and the differences between intermolecular and intramolecular bonds. The Student practiced identifying molecular shapes based on the number of lone pairs and bonding pairs of electrons, and the Tutor assigned further practice problems for the next session.
