O Level Sci Chemistry - 2019 Section A

Hi there, This is the video tutorial of the 2019 paper, Section A. Concepts being tested here include: Atomic structure - relative mass and relative charge of sub-atomic particles Organic chemistry (Alkane, Alkene reactions)  Separation Technique (fractional distillation)  Kinetic Particle Theory (arrangement and movements of solid and gas)  Mixture vs Compounds  Speed of reaction (drawing graph and explain the shape of graph)  Writing chemical formula  Video link:  2019 Sci Chem - Section A “Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.” – Thomas A. Edison Till next time!
