Year 11 Preliminary Chemistry: Main Types of Chemical Reactions (Module 3)

Let’s explore the Main Types of Chemical Reactions (Module 3 Preliminary Chemistry)

Hosted by our Talent 100 Academic Director Dr Nikhil Vasan, we’re going to break down a few of the most important topics for each section of Module 3: Metal Activity Series and Displacement Reactions for Preliminary Chemistry (Year 11).

In this episode of Preliminary Chemistry Talent Teaching Series, we’ll be taking a look at Synthesis Reactions, Decomposition Reactions, Combustion Reactions and Precipitation Reactions which form a really part of Module 3: Reactive Chemistry.

Synthesis Reactions

As the name suggests, Synthesis reactions are when two different substances combine and they form one substance. We can generalise this by saying that:

A + B → AB

The important thing here is that A and B now become chemically bonded. For example if you just put sand in water, that’s not a synthesis reaction because the sand is not chemically bonding with the water. But we can think of some examples were situations where two substances do combine chemically. Now this can be an ionic bond, or it can be a covalent bond as well.
