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!

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
Student and Tutor reviewed and practiced various Chemistry concepts including balancing equations, naming compounds, limiting reagents, gas laws, redox reactions, empirical and molecular formulas, and chemical bonding. They also worked through multiple-choice questions covering these topics, and the Tutor provided a cheat sheet for Lewis structures for Student's further revision.
Chemical Separation Techniques
Chemical Naming Conventions
Determining Empirical and Molecular Formulas
Oxidation and Reduction (Redox Reactions)
Types of Chemical Bonds
Gas Laws and Unit Conversions
Student and Tutor reviewed chemistry homework covering calculations involving moles, grams, scientific notation, and significant figures. They then practiced balancing chemical equations, stoichiometry, identifying limiting reagents, and naming chemical compounds and writing formulas. For future sessions, they plan to cover empirical/molecular formulas, redox reactions, acid-base chemistry, gas laws, kinetics, and bonding, with relevant homework assigned.
Balancing Chemical Equations
Stoichiometry Fundamentals
Identifying Limiting Reagents
Chemical Nomenclature (Compound Naming)
Chemical Formula Derivation
The Tutor and Student reviewed core chemistry concepts, including the periodic table, atomic structure, and mole calculations. They practiced problems involving molar mass, Avogadro's number, molarity, and dilutions, with the Student assigned practice questions for homework.
Atomic Structure and Periodic Trends
Moles and Avogadro's Number
Molarity and Dilution
The student and tutor covered nucleophilic substitution (SN1, SN2) and elimination (E1, E2) reactions in organic chemistry. They practiced identifying reaction types, predicting products, and understanding mechanisms, with a focus on carbocation stability, steric hindrance, and stereochemical outcomes. The tutor also clarified acid-base definitions.
SN1 vs. SN2 Reactions
E1 vs. E2 Reactions
Acids
Bases
and Nucleophiles
Stereochemistry in SN1 and SN2
Zaitsev and Hoffman Products
The Student and Tutor engaged in a comprehensive review session for an upcoming Chemistry exam, working through multiple-choice questions, stoichiometry calculations, and balancing redox reactions. They also discussed the impact of temperature on reaction spontaneity and practiced determining empirical and molecular formulas. The session served as final preparation, with the Tutor encouraging the student to reach out with any further questions before the exam.
Balancing Redox Reactions: Half-Reaction Method
Factors Affecting Chemical Spontaneity
Determining Empirical and Molecular Formulas
Student and Tutor covered key Chemistry concepts including naming ionic and covalent compounds, writing chemical formulas, and reviewing homework on limiting reagents, and empirical and molecular formulas. They also practiced unit conversions and scientific notation. The plan for the next session includes further practice on unit conversions, acids and bases, and working through a full chemistry paper.
