The Student and Tutor reviewed balancing chemical equations with a practice problem. They then thoroughly discussed various types of chemical reactions, including combination, decomposition (thermal, electrolytic, photolytic), displacement, and double displacement reactions. The session also covered oxidation, reduction, and redox reactions, with the Student identifying oxidized and reduced species in examples. Homework was assigned to practice these concepts further.

The Tutor introduced the concept of chemical reactions and equations, defining key terms like reactants and products. The Student practiced balancing chemical equations, learning how to represent physical states and apply the law of conservation of mass. The next session will cover different types of chemical reactions, and the Student was assigned several balancing problems as homework.

The Tutor and Student worked on forming chemical formulas and calculating atomic masses of compounds. They reviewed concepts of isotopes and isobars, practiced calculating average atomic masses, and then focused on deriving chemical formulas from ion charges. The session concluded with extensive practice on calculating the molecular mass of various chemical compounds.

The Tutor and Student reviewed fundamental concepts in chemistry, including types of substances, mixtures, and atomic structure models from Thomson to Rutherford and Bohr. They practiced calculating atomic components, differentiating isotopes, and forming chemical formulas based on valency and polyatomic ions.

The Tutor and Student explored fundamental concepts in chemistry, starting with matter classification and moving into atomic structure, electron configurations, and chemical bonding. They discussed the formation of ions and molecules, the discovery of subatomic particles, and the properties of elements. The session concluded with a preview of upcoming topics like the periodic table and chemical equations.
