Synthesis reactions (also called combination reactions) are the simplest type of chemical reaction.  In a synthesis reaction two or more substances undergo a chemical reaction producing a new substance.  This is written in the general format of:

A +  B  yields  AB

An example of synthesis reaction is hydrogen and oxygen gas reacting to form water.

H2 + O2   yields   H2O

Here, the H2 and O2 combine to form water.  Since we have two substances reacting for form a single substance this is considered a synthesis reaction.

Synthesis reactions in the video:
Fe + O2    yields   Fe2O3    -- at beginning of video
Mg + O2   yields    MgO   -- middle of video

Note that we don’t consider the coefficients used to balance the equations when determining if a reaction is synthesis.  For example:

2Fe + 3O2   yields   2Fe2O3  

It is still considered synthesis.
