<span>Scientific knowledge
can be gained through experiment by doing a thorough experimental procedure
that will enable to answer the objectives of the experiment that will lead to a
scientific knowledge. Through experimentation you can know the behavior of a
variable with respect to a certain variable. This can also answer some
knowledge gap about certain topic</span>
In this case, in order to establish the different types of chemical reactions, several experiments are carried out the determine whether a chemical reaction is synthesis, decomposition, double displacement, double displacement or combustion. Such experiments consist on the combination of different of reactants under varied conditions in order the appreciate the reaction behavior over the time, changes in color, temperature changes and formed products that suggest the type of reaction.
Once the observations are set throughout the experiments, one provides the scientific knowledge that in this case will help to differentiate such types of chemical reactions.
