Chapter III The characteristic of elements, chemical compound, and mixture

Chemical element is only one substance that can be parted to be another substance by chemical reaction. The element consists of metal and non- metal. The pure substance has characteristic that can be differences with another substances. For example, hydrogen is only arrange of hydrogen atom. Oxygen is only arrange of oxygen atom. The characteristic of oxygen and hydrogen is not appear on the substance that formed both of, such as water(H2O).

Chemical compound is composite of several elements that forming in chemical reaction. The chemical compound has different characteristic with its arrangements. It is written in chemical reaction. The chemical reaction is substance that consists of symbol grouping with specific composition.

The characteristic of chemical compound Comparing the characteristic of chemical element with the chemical compound that formed for arrange the substance. Such as, C2H4 (Etena), H2O (water). Empirical formula is the chemical formula that said about little comparing the atoms quantity of the chemical compound former.

Mixture is composite of several substance with unconstraint comparing without chemical reaction.

Homogeneous Mixture of water with sugar named sugar solution Heterogeneous Land Water of river Foods

NoMixtureChemical compound It is forming without chemical reaction. Comparing of element of mass and compound is inconstant. It is arranged of several elements or chemical compound. The arrangement component characteristic of mixture is depend on each of characteristic. It is process physics the arrangement component of mixture detachable. It is forming with chemical reaction Comparing of element of mass and compound is constant. It is arranged of only several of elements. The arrangement component characteristic of chemical compound is different with in origin. It is process physics the arrangement component of compound detachable.
