Why chemistry clicks on a board
Chemistry asks you to picture things too small to see. Litu draws them: the shells of an atom, the shared electrons in a bond, the shape of a molecule. When you balance an equation, it writes each step and rings the coefficient it just changed, so you see the atoms add up on both sides.
Questions you can ask
- How do I balance this equation?
- What actually is a mole?
- Why is water a bent molecule?
- What's the difference between ionic and covalent bonds?
- Why does ice float?
Topics Litu covers
- Atoms and the periodic table: atomic structure, electron configuration, periodic trends.
- Bonding and structure: ionic, covalent and metallic bonding, shapes of molecules.
- Equations and calculations: balancing equations, the mole, concentration, gas volumes.
- Reactions: acids, bases and salts, redox, rates of reaction, equilibrium, basic organic chemistry.
For WAEC, NECO and JAMB chemistry
Litu explains the topics on the senior secondary chemistry syllabus step by step. Snap a past question or a page of your notes and it teaches from your own material. See exam prep with Litu.
How a chemistry lesson goes
- Ask about the reaction, the calculation or the idea that confuses you.
- Litu draws it out and explains each step as it writes.
- A quick question at the end checks it made sense.
