Kelechi Your chemistry tutor
I'm Kelechi Chioma, A Biology and Chemistry tutor with over 24 years of experience. I hold a Bachelor's degree in Biochemistry. My Specialties include tailor-made learning approach, Exam focus teaching, and real world application of concepts. I work with student across all strata including primary, secondary and tertiary levels. I provide engaging sessions to enhance understanding. For students with special needs, I ensure a supportive and inclusive learning environment. I encourage a lot of questioning and practice especially of past exam papers. I push students to also study on their own. devoting study habits and methods for students and learners. I source for the best materials whether online or offline that will help students grasps the concepts better and quicker. Learners are motivated. Lets ace Biology and chemistry together.
Kelechi graduated from Nnamdi Azikiwe University

Chemistry class overview
My tutoring method is interactive, engaging and exam focused, providing personalised tutoring in various chemistry subjects like Chemical bonding, Organic Chemistry and many more. I use a blend of of tech tools, like online collaboration platforms, digital simulations and interactions. I make learning dynamic and hands-on. Following a structured curriculum, I ensure students grasp the complex concepts through a mix of theory and practical applications. I know how to make the hard things simple and explain the complicated aspects of each topic. With over 500 students thought both online and physical I bring to bear over 24 years teaching experience. my hands-on teaching style ensures the deep understanding of the subjects, leading to improved academic performance and exam success. Leaving my students with subject knowledge they will use for a life time.

Chemistry concepts taught by Kelechi
The Student and Tutor covered fundamental biochemistry concepts, including the definitions and interconversion of monomers and polymers via condensation and hydrolysis. They discussed the four major biological macromolecules—carbohydrates, proteins, nucleic acids, and lipids—and their respective building blocks and bonds. The session also involved analyzing the polarity and solubility of various organic molecules and a detailed comparison of DNA and RNA structures and functions, concluding with the differences between prokaryotic and eukaryotic cells.
Carbohydrates – Sugars for Energy & Structure
Prokaryotic vs. Eukaryotic Cells – Fundamental Cell Organization
RNA – The Reactive Information Expresser
DNA – The Stable Genetic Archive
Nucleotides – The Blueprint's Fundamental Units
Proteins & Lipids – Diverse Roles & Unique Structures
Monomers & Polymers – The Building Blocks of Life
The tutor provided an introductory lesson on the core concepts of biology, starting with the definition and characteristics of living organisms. The session then moved to foundational cell biology, covering the cell theory, prokaryotic vs. eukaryotic cells, and a detailed comparison between plant and animal cells, including their organelles and functions.
Prokaryotic vs. Eukaryotic Cells
Plant vs. Animal Cell Organelles
The Cell Theory
Definition and Characteristics of Life (MRS GREN)
The Student and Tutor worked through a series of advanced chemistry problems covering topics such as thermochemistry, intermolecular forces, density, stoichiometry, solution chemistry, and gas laws. They collaboratively solved problems involving calculations for enthalpy of neutralization, percentage yield, partial pressures, and the number of atoms in a hydrate. At the end of the session, the Tutor and Student discussed starting biology basics before the Student's official class begins in August.
Mass from Molarity and Volume
Calculating Atoms in Hydrate Compounds
Partial Pressure (Dalton's Law)
Percentage Yield in Reactions
Density and Volume Displacement
Identifying Intermolecular Forces (IMFs)
Enthalpy of Neutralization (ΔH)
The Student and Tutor reviewed various advanced chemistry concepts and problem-solving techniques, including theoretical yield, molecular formula determination from percentage composition and gas density, writing ionic equations, calculating molar concentrations, and titration. They also covered enthalpy changes from reactions and bond enthalpies, and extensively discussed the definitions and identification of oxidation-reduction reactions and agents. The next session was scheduled to continue their review.
Ionic & Net Ionic Equations
Redox Reactions: Oxidation & Reduction Agents
Enthalpy Change (ΔH) & Heat Released
Titration Calculations
Empirical & Molecular Formulas from Composition
Limiting Reagent & Theoretical Yield
Molar Concentration of Ions in Mixed Solutions
The Student and Tutor reviewed various chemistry concepts, including molecular geometry, VSEPR theory, polarity, and periodic trends such as ionic radius, lattice energy, melting points, ionization energy, and electron affinity. They worked through specific examples provided by the Student and clarified conceptual misunderstandings related to electron domains, bond angles, and the reasons behind periodic trends. The Tutor confirmed availability to assist the Student with biology in the upcoming semester, addressing the Student's future academic plans.
Isoelectronic Series & Ionic Radius Trends
Electron Affinity (EA)
Ionization Energy (IE)
Melting Points: Lattice Energy & Ionic Radius
VSEPR Theory: Molecular Geometry & Polarity
The Student and Tutor worked through several advanced chemistry problems, including calorimetry calculations, bond enthalpy determinations, photon energy and wavelength calculations, and applications of Hess's Law. They focused on correcting the Student's approach to these problems and clarifying formulas and concepts. The Student has an upcoming test on these topics and plans to engage in more practice.
Calorimetry: Calculating Heat Transfer (Q) and Enthalpy Change (ΔH)
Bond Enthalpies: Estimating Enthalpy Change (ΔH)
Photon Energy and Wavelength Calculations
Hess's Law: Combining Reactions for ΔH
