Although the examples of chemical change in everyday life are many, the spontaneous formation of this concept in
the context of everyday life is almost impossible, because firstly it depends on an empirical scope of academic
origin and secondly, the notion of chemical transformation is almost absent in both spirit and in everyday language,
and so something burning, for example, is perceived more as a destruction than combustion.
These obstacles are real persistent discomfort at the unconscious level of the student and hinders the formation of
concept model or modeling the concept of chemical reaction is also important in teaching than in learning chemistry
