The chemical reaction speed is the change in the concentration and the resultants in a unit time, The chemical reactions differ in the time that they take to occur, At the end of the...
The covalent bond The covalent bond is a bond occurred among the atoms of nonmetals through the participation of each atom with the same number of electrons to complete the outer electron shell.
Physical properties of the water The water has a higher melting point, boiling point, and heat of vaporization than most common liquid. This fact indicates that there are strong forces of attraction between the...
