Stoichiometry, mole concept and redox are the first few topics you will learn in your A Level Chemistry. In this course, I've divided it into two parts. Part (1) is on mole concept and stoichiometry, while part in part (2) we will look at redox.
We will start off with mole concept and stoichiometry by revising the following topics learned in O Leve:
Finding relative atomic mass (Ar) and relative molecular mass (Mr)
What's mole and Avogadro's constant
What's molar mass and finding molar mass
Finding moles from mass
Finding mole ratio from chemical equations or stoichiometry
Finding empirical and molecular formulae
Finding volume of gases
Concentration (in mol/dm3 and g/dm3)
Limiting and excess reagents in chemical calculations
Finding percentage purity and percentage yield
Then we will go on to cover the following topics:
Go through A Level Chemistry questions on mole concept and stoichiometry
Next, we will cover redox. In redox, we start off by revising the topics covered in O Level:
Oxidation and reduction ( in terms of oxygen, oxidation number, electrons and hydrogen)
oxidising and reducing agents
Next, we will cover new concepts:
Writing redox half equations in acidic and alkaline medium
Common redox reactions
Go through A Level questions on redox
To be able to do well in this course, you will need to have good basic foundations in chemistry which include writing formula of compounds/ molecules, and writing chemical and ionic equations.
This course covers the first few topics you will learn in A Level Chemistry, and are important topics to help you build your foundation in Chemistry. So try this course, and build up a good foundation in A Level Chemistry, so that you'll ace this subject.
I'll see you inside this course.
