Chemistry for junior high school, "How to Write Chemical Formulas".

The formula that represents the composition of matter with an element symbol. Chemical formula is a general term for experimental, molecular, structural, and indicative formulas. The chemical formula that uses chemical symbols to express the atomic ratio of each element in a compound is called an experimental formula, such as acetylene and benzene are both hydrocarbons, their composition is carbon-contained, hydrogen-contained, and the atomic ratio of carbon and hydrogen is 1 1, and the experimental formulas of acetylene and benzene derived are CH.

Some inorganic compounds (such as sodium chloride) are composed of ionic crystals, and cations and anions are alternately arranged inside the crystals, and now, the question of how many sodium ions and chloride ions are in the sodium chloride crystal has not been solved, only NaCl 1 1 is known, so only the experimental NaCl can be used to represent sodium chloride. with chemical symbols.

The chemical formula that represents the composition of the molecules of a substance is called the molecular formula, and its meaning is: the elements that make up the compound; the ratio of the atomic number of each element; The sum of the weights of the atoms of each element. The way in which the chemical structure between the individual atoms in a compound is represented by chemical symbols and valence bonds is called.

Structural formula, which points out the order in which the atoms are arranged and connected in a molecule, organic compounds are often represented by structural formulas, which can eliminate the shortcomings of the same molecular formula representing different compounds due to isomerism. For example, n-butane and isobutane both have the molecular formula C4H10 but the structural formula is different.

It can be seen that the structural formula clearly distinguishes n-butane from isobutane. The simplified structural formula that indicates the order of the atoms in a compound is called the indicative formula, such as the indicative formula of ethanol is C2H5OH.

Chemical Formula = Molecular Formula.

A chemical formula is a formula that combines the symbols of elements to represent the composition of substances (including elemental substances and compounds). The chemical formula only indicates a pure substance, and the mixture does not have a chemical formula.

Empirical

form) compared to the molecular formula, which only represents the ratio between the elements in the individual molecules of the compound. For example, hydrogen peroxide (H2O2) is only denoted as Ho in its simplest form, even though it contains two hydrogen atoms and two oxygen atoms in one molecule. Another example is n-hexane (C6H14), which is denoted as C3H7 in its simplest form.

The simplest form cannot represent the specific number of atoms in a molecule, nor can it represent the molecular structure. The minimalist form plays an important role in the analysis of the quantity fraction of an element in a substance.

Structural Simplified = Structural Formula.

The structural formula represents the spatial structure of the molecule, and the organic compound is generally expressed by a simple structural formula (the carbon-hydrogen bond is generally omitted, and sometimes the carbon-carbon single bond is omitted, which is represented by a broken line).

I can't find the real form, sorry....

Common chemical formulas in junior high school CO, HCl HCl, NaCl chloride, aluminum sulfate A12(S04)3, carbon dioxide C02, nitrate HN03, potassium chloride KCL, ferrous sulfate FeSO4, sulfur dioxide S02, sulfuric acid H2S04.

There are a lot of chemical formulas today, and there are a lot of chemical equations that are the supernumerous number of reactions.

There used to be a lot of programmatics. For example, some of our common things can be used for experiments.
