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.

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

Student learned 2 days ago

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.

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.
