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 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.
Atomic Structure and Symbolism
Isotopes and Average Atomic Mass
Empirical
Molecular
and Isomeric Formulas
The Periodic Table: Organization and Trends
Chemical Bonding and Nomenclature
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.
Chemical Nomenclature Principles
Intermolecular Forces (IMFs) & Polarity
Bond Order and Molecular Stability
Paramagnetism vs. Diamagnetism
Acid Naming Conventions (Oxyacids)
The Student and Tutor established a General Chemistry 1 study plan, integrating lecture, lab content, and MCAT preparation. They reviewed fundamental concepts including the definition and classification of matter, physical and chemical properties, lab safety, and measurement principles like uncertainty, accuracy, and precision. The session concluded with the Student successfully answering conceptual questions, and the next class is planned to cover atoms, molecules, and ions.
Classification of Matter: Pure Substances vs. Mixtures
Physical vs. Chemical Properties and Changes
Chemical Properties and Changes
Accuracy
Precision
and Uncertainty in Measurements
Scientific Terminology: Law
Theory
Student and Tutor worked through a diagnostic General Chemistry exam focusing on bonding and nomenclature. They reviewed and explained answers related to ionic and covalent bonding, ion formation, formal charge, molecular polarity, octet rule, lone pairs, molecular geometry, resonance, and compound nomenclature. The Tutor identified content gaps in understanding periodic table trends and complex naming conventions and planned to provide a VSEPR chart and condense lectures for these topics for future sessions.
Chemical Nomenclature Rules
Molecular Geometry and VSEPR Theory
Formal Charge Calculation
Bond Polarity and Periodic Trends
Ion Formation & Oxidation-Reduction
Types of Chemical Bonds
The Student and Tutor reviewed rate laws and integrated rate laws, focusing on first-order reactions and the calculation of rate constants. They addressed the Student's difficulties with applying the equations and using a calculator, and planned to restart the topic with dedicated lecture and practice sessions.
Rate Laws and Reaction Orders
Integrated Rate Laws
Experimental Determination of Reaction Order
The student and tutor reviewed and practiced chemistry concepts related to formal charge, resonance, acid-base theory, and molecular hybridization. They worked through practice problems to solidify understanding and identified areas for future study, specifically nomenclature and bonding.
Molecular Polarity: Bonds vs. Overall Molecule
Acidity and Basicity: Factors Affecting Strength
Acid-Base Theories: Brønsted-Lowry vs. Lewis
Resonance Structures and Stability
