Revise Chemistry with Mr B
With over 25 Years of experience Teaching Chemistry at a very successful school, Mr B will help you fulfil your potential in your GCSE chemistry exam. All videos are helpfully arranged into playlists according to which Chemistry topic they are part of. Also check out the exam question "walk through" videos where Mr B explains how to answer different exam style questions.
Private Tuition
If your child would like extra help with their GCSE Chemistry via online tuition on Zoom, please use the link at the top of this page and complete the online form. I will get back to you as soon as possible to discuss how I may be able to help.
Chemistry Paper 1
Atomic Structure
This first part of the topic covers atoms and the subatomic particles that they are made from: Protons, neutrons and electrons. We also find out what isotopes are. The second part of the topic is about separating techniques such as filtering , distillation and chromatography.
The Periodic Table
In this topic you learn about The Alkali Metals (Group 1), The Halogens (Group 7) and the Noble Gases (Group 0). You will also learn the different ways that scientists tried to arrange the elements before Dmitri Mendeleev came up with a Periodic Table similar to the one we have today.
Structure and Bonding
Structure and Bonding is a big topic and one which you really need to know for paper 1. There are also links to many other topics so if you have a good understanding of structure and bonding it will help your overall understanding of chemistry.
Chemistry Paper 2
Rates of Reaction
In these video tutorials you will learn how to calculate the rate of a chemical reaction. You will learn how the rate of reaction can be affected by temperature, concentration, surface area and catalysts. You'll discover what a reversible reaction is. Higher Tier students will learn how Le Chatelier's principle can be used to predict the effects of changing the conditions of a reversible reaction.
Organic Chemistry
Find out what a hydrocarbon molecule is. You will learn how to write the molecular formula and draw the displayed formula of alkanes and alkenes. You will discover how fossil fuels like crude oil and coal were formed. You will find out how we get useful products from crude oil by fractional distillation, cracking and polymerisation.
Chemical Analysis
In this topic you will learn the difference between a pure substance, mixture and compound. You'll discover how a substance's melting point can be used to determine if it is a pure substance or a mixture. You will be able to analyse a substance using chromatography and calculate Rf values. You will also learn the different tests for gases.
