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 tutor and student reviewed fundamental concepts of thermal physics, including temperature, thermal energy, heat, and the ideal gas law. They practiced unit conversions, applied the ideal gas law to solve for moles, and discussed the Maxwell-Boltzmann distribution and its relation to particle speed and temperature.
Temperature vs. Thermal Energy vs. Heat
Ideal Gas Law and its Components
Maxwell-Boltzmann Distribution
Absolute Zero and Temperature Scales
The student and tutor worked through practice problems focusing on stoichiometry, molar mass calculations, Avogadro's constant, and thermochemical principles including endothermic and exothermic reactions. They discussed problem-solving strategies for heat and work calculations and applied these to relate reaction enthalpies to mass and moles of substances. Future sessions were planned to cover Lewis structures.
Moles and Chemical Formulas
Stoichiometry and Mole Ratios
Thermochemistry: Endothermic vs. Exothermic Processes
Avogadro's Constant and Molar Mass
Stoichiometric Calculations Using Enthalpy Changes
Calorimetry: Heat Capacity and Temperature Change
The tutor and student reviewed various chemistry concepts including molecular orbital theory, covalent bonding, Lewis structures, formal charges, intermolecular forces (LDFs, dipole-dipole, hydrogen bonding), hybridization, molecular geometry, and resonance structures. They worked through several practice problems and discussed concepts related to bond polarity, bond order, and molecular properties.
VSEPR Theory and Molecular Geometry
Lewis Structures and Formal Charge
Molecular Orbital Theory and Bond Order
Intermolecular Forces (IMFs)
The tutor and student reviewed intermolecular forces (London dispersion forces, dipole-dipole, and hydrogen bonding) and their relationship to boiling points. They practiced predicting boiling points based on molecular structure and intermolecular forces, and discussed the concept of distillation as a separation technique. The tutor also explained 3D molecular representation using wedge and dash notation.
Intermolecular Forces Hierarchy
London Dispersion Forces (LDF)
Hydrogen Bonding
Boiling Point Prediction
Distillation and Boiling Points
The tutor and student reviewed concepts related to enthalpy, exothermic and endothermic reactions, and heat capacity calculations. They practiced solving problems involving calorimetry, including determining heat of combustion, enthalpy of reaction, and temperature changes. The student will continue practicing these concepts for an upcoming test.
Combustion Reactions
Calculating Enthalpy of Reaction
Enthalpy and Reaction Types (Exothermic/Endothermic)
Calorimetry and Heat Capacity
The Tutor and Student reviewed intermolecular forces (IMFs) and their relationship with boiling points, covering London Dispersion Forces, dipole-dipole interactions, and hydrogen bonding. They practiced identifying IMFs in different molecules and predicting boiling points based on IMF strength. The next session is planned for Friday to prepare for a test on Monday.
