Most schools cover the transition element topic last in the H2 A Level Chemistry syllabus. This topic is usually consists of very thick notes, and…
In organic chemistry for O Level Chemistry, students are expected to know the reactions, properties and structures of alkanes, alkenes, alcohols, carboxylic acids, and esters. Here’s a one- page summary of organic chemistry topics as tested in O Level Chemistry.
In this post, we’ll look at a simple electrochemical cell, a simplified setup of it, and how it acts as a cell (to produce electricity).
In this post, we’ll look at the electrolytic cell, a simple setup of it, and how to determine the products at the cathode and the anode.
In this post, we’ll look at what are redox reactions, and define oxidation and reduction in terms of (i) oxygen (ii) hydrogen (iii) electrons and (iv) oxidation number.
In this post, we’ll look at endothermic and exothermic reactions, and examples of such reactions.
In this post, we’ll look at what is needed for a reaction to take place, and the factors that affect rate of reaction.
In this post, we’ll look at what is rusting, the conditions needed for rust to be formed, and how to protect iron from rusting.
In this post, we’ll look at some common properties of metals, and explain the chemistry reason behind them. These properties include why pure metals are soft, why they are good conductors of electricity, and why they have relatively high melting and boiling point.
In this post, we’ll look at the reactivity series of metals (tested in the O Level exam), and then have a look at some of…
