Chemical elements are also described using symbols. These short forms of chemical elements are useful to scientists as it has made their job much easier. It would have been time consuming if they were have to write full names while doing their paper work.

∙ 12y agoThe blunt answer is they're not. They don't give any information about the reactivity of compounds. What they do tell you is a rough (slightly misleading) distribution of the valence charges around each of the atoms, and a basic structure. So do they do have some utility as a descriptive tool.

∙ 10y agoA chemical formula tells you what that chemical is made of. It tells you what elements it contains and in what ratio, and even, in the case of organic chemistry, the arrangement of those elements. If you are engaged in any kind of chemistry, for example, the synthesis of that chemical, then you will naturally need that information.

∙ 11y agoSymbols are easier to use rather than their systematic names when it comes to balancing chemical equations as the symbols are shorter and easier to recognize. Let us take the reaction between sodium hydroxide and hydrochloric acid as an example.
Corresponding word equation:
Aqueous sodium hydroxide + Aqueous hydrochloric acid -> Aqueous sodium chloride + Liquid water
Corresponding equation with symbols:
NaOH(aq) + HCl(aq) -> NaCl(aq) + H2O(l)

The chemical formula of decane is C10H22.
To write a sentence using the term "chemical formula," you can say: "H2O is the chemical formula for water." This simple example showcases a chemical formula and relates it to a common substance.
The chemical formula for calcium phosphide is Ca3P2.
The chemical formula for calcium silicate is CaSiO3.
The chemical formula for barium fluoride is BaF2.
The chemical formula of methane is CH4.
The chemical formula for calcium sulfate is CaSO4.
The chemical formula for hydrochloric acid is HCl.
The chemical formula of ammonium hydroxide is NH4OH.
The chemical formula for Sodium Oxide is Na2O.
The chemical formula of dilithium carbonate is Li2CO3.
For correction purposes the correct way to write this is H2O and it is the chemical formula for water.
The chemical formula of chlorous acid is HClO2.
