Chirani Your chemistry tutor
I am Chirani Thammita Lennon who is an experience chemistry tutor for nearly a decade. I an experienced in guiding high school and college students with any needs through the guidance to make chemistry an enjoyable subject. I specialize in subjects like biochemistry, organic chemistry, atomic structure, and more in depth knowledge on the lab skills. Grasping complex concepts in chemistry is nothing to do with your knowledge but the way you approach it. Make chemistry a story, game or a fantasy novel. You just need to know the easy tricks all chemists use to gain their success. That’s where I come to play. I excel in covering all bases that is needed for you to excel in homework, lab assignments, group work and assignments that get You points and bonus points. Grades will be nice but understanding the concepts of chemistry is more important. Make sure you are comfortable with this “hard” subject!
Chirani graduated from PennWest University Edinboro

Chemistry class overview
My tutoring style structured, patient, interactive, and engaging, focusing on hands on learning experiences. I specialize in teaching chemistry in all sub groups such as states of , acid, bases and pH. It doesn’t matter if you want help in general chemistry or organic chemistry, i will help you succeed by making you understand the concept with the technique you prefer. Everyone studies and retain information different, spring feel afraid to reach out to tell me what you are compatible and comfortable with. My teaching techniques all include presentations, diagrams, note taking, color coding and many more. The most important method of teaching is communication. I like when You can contact me when you have any questions about any material we covered or any material you don’t understand but needs ur get help with. Therefore, let’s navigate chemistry together!

Chemistry concepts taught by Chirani
The Student and Tutor engaged in a comprehensive chemistry session, covering the nature of light, wave properties, electromagnetic energy, and an introduction to the photoelectric effect and line spectra. They also discussed the foundational concepts of the Bohr model, specifically differentiating between grounded and excited electronic states. The next session is planned to continue with the Bohr model, quantum theory, and electronic configurations, focusing on a one-hour format.
The Photoelectric Effect & Quantum Energy
Electromagnetic Spectrum & Wave Properties
Atomic Emission Spectra: Line vs. Continuous
Rydberg's Formula & Bohr's Atomic Model
The Student and Tutor discussed the Student's current General Chemistry lab, which involves identifying an unknown compound through various tests, and compared it to more rigorous STEM lab formats. The majority of the session was dedicated to the Student completing a practice paper on fundamental chemistry concepts, followed by a thorough review of the answers. For the next session, they plan to cover bonding, molecular structures, and VSEPR theory.
General Chemistry Lab Experience & Structure
Qualitative Analysis: Identifying Unknown Compounds
The Mole Concept and Avogadro's Number
Calculating Molar Mass
The Student and Tutor discussed the Student's General Chemistry lab and lecture experiences, covering lab procedures, group dynamics, and the slow pace of the lecture class. They then focused on reviewing and practicing calculations related to molarity and dilutions, including defining key terms like solvent and solute. The session concluded with planning a practice exam on foundational chemistry topics and outlining future lessons on molecular geometry and stoichiometry.

Digital Lab Notebook: Lab Archives
Solute and Solvent Basics
Determining Lab Glassware Accuracy
Dilution Equation
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.

Percent Composition
Empirical Formula Determination
Molecular Formula Determination
The Student and Tutor reviewed core General Chemistry topics, including atomic structure, isotopes, and the calculation of average atomic mass. They further discussed different types of chemical formulas, such as molecular and empirical, and their interconversion. A significant portion of the session was dedicated to the periodic table, its historical development, group classifications, and key periodic trends. The Student also practiced chemical nomenclature for ionic and covalent compounds and discussed preparation for upcoming lab sessions.

and Isomeric Formulas
Student and Tutor reviewed chemistry concepts, including chemical nomenclature, intermolecular forces, bonding, and bond order, by working through multiple-choice practice questions. They identified areas where the Student needed to reinforce fundamental rules and critical reasoning skills. The Tutor encouraged the Student to continue studying a provided chart on bonding and noted the challenging questions were designed to boost critical thinking.
