One of the first reactions to explain is Decomposition.Decomposition is the separation of a substance into simpler substances or also basic elements.It can be shown about by exposure to heat,light,and chemical or biological activity.Decomposition …show more content…
Precipitation is another form of a chemical reaction and it shows how a solid will form.It is basically showing when an solid emerges from a liquid solution.That solid would be insoluble which is an object or substance that would be incapable of being dissolved,mostly in liquids. The insoluble object/substance would separate from the liquid and will be called a precipitate.An example of this reaction would be AgNO3 (aq)+ NaI (aq) → AgI (s) + NaNO3 (aq) and shows the solid forming and
