THE Chemistry é a branch of the Natural Sciences that studies matter, its properties, constitution, transformations and the energy involved in these processes.
School subjects it is the main object of study in Chemistry and can be defined as everything that occupies space in space and has mass, that is, the entire material world around us, including ourselves.
Regardless of shape, origin (present on our planet or in the universe) or whether alive or dead, there is no material that is beyond the reach of Chemistry.
The chemistry it has an enormous impact on technology and our society, as its studies play a fundamental role in the development of all branches of science. After all, it is through the study of matter that we can understand the properties and possible transformations that each substance can undergo to then use this knowledge to our benefit.
It is very easy to see the various contributions provided by Chemistry throughout human history. Among them, we can highlight:
The development of processed foods;
Increased shelf life of products;
Increased effectiveness and action of cosmetics;
Development of medications to combat the most varied diseases;
Development of alternative fuel sources;
Production of substances in the laboratory;
Development of techniques and solutions for environmental problems.
Chemistry is a science of three fundamental levels:
1. Macroscopic: Transformations that can be observed, that is, it deals with properties involving large and visible objects;
Do not stop now... There's more after the advertising ;)
2. Microscopic: It is the interpretation of macroscopic phenomena through transformations that we cannot see directly, such as the rearrangement of atoms;
3. Symbolic: Chemical symbols, such as molecular, structural and electronic formulas, as well as mathematical equations and formulas, are used to represent the studied transformations and phenomena.
In this space, you can clarify each of the doubts you have about the most varied themes and questions that involve Chemistry, that is, all the knowledge related to main areas of chemistry required in the entrance exams still in force and in Enem, namely:
General chemistry:

- Bases
- Oxides
- Salts
- Chemical reactions related to the substances highlighted above
