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:

  1. Atomic structure - relative mass and relative charge of sub-atomic particles
  2. Organic chemistry (Alkane, Alkene reactions) 
  3. Separation Technique (fractional distillation) 
  4. Kinetic Particle Theory (arrangement and movements of solid and gas) 
  5. Mixture vs Compounds 
  6. Speed of reaction (drawing graph and explain the shape of graph) 
  7. Writing chemical formula 

“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!

Good morning good morning, Two topics coming right up in this post! A summary of popular questions based on the topics: Elements, Compounds and Mixtures Distinguishing the diagrams for elements, compounds, mixtures Note: Elements can exist as atoms / molecules [Refer to question 1, diagram R and S respectively] Common examples of mixtures - air, crude oil / petroleum / seawater / alloys e.g. brass, steel Good to know: the definition of elements, compounds, mixtures as it will guide you towards identifying them.  Video tutorial for elements, compounds, mixtures:  N level Sci Chem - Elements Compounds Mixtures Atomic Structure  The three subatomic particles and their relative charges and approximate relative massess.  'Location' of the three  subatomic particles. Define isotopes and describe similarity / differences in given isotopes (See Section B, question 1)  Writing electronic configuration, drawing electronic structure of atoms and ions  Descr
