Salt


Salt is any substance that dissolves in water by conducting electricity. The cooking salt is represented by the substance sodium chloride - NaCl - that is an ionic compound constituted by the ions Na + and Cl - organized through a crystalline reticulum. When the crystalline reticulum of sodium chloride comes into contact with water, a separation of ions occurs, a phenomenon called ionic dissociation. The free ions obtained after dissociation are responsible for the electrical conductivity. (Svante Arrhenius).

Periodic table

Imagem
The elements were organized by the professor of the University of St Petersburg, Dimitri Ivanovich Mendeleev, who wrote a book about the chemical elements, were about 63 elements, and Mendeleev organized them by function of the mass of their atoms establishing families and groups. The elements in the table are organized horizontally, in numerical sequence, according to their atomic numbers, and are organized through periods and families. There are seven periods in the table and the amount of electronic layers that the chemical elements present is indicated by the period number, they represent the horizontal rows of the table.  References: Periodic table families.

Photosynthesis

Imagem
Chemical Reaction:6 CO 2 + 6 H 2 0 => C 6 H 12 O 6 + 6 H 2 O The chemical reaction that basically occurs in photosynthesis is that the plant captures sunlight through the pigments in the leaves, absorbs water and minerals from the Earth by the root of the plant and also absorbs the carbon dioxide from the air, passing through a chemical reaction, releasing the oxygen we breathe, and producing the sugar that is its food.
