The words like symbol, equation, ion, valency, atom, particle, molecule, reaction, and so on are all used in chemistry. In short, a chemical symbol signifies a certain element or an atom of that element. Chemical reactions are often simpler to write with chemical symbols than with long chemical names. Several scholars have devised several mechanisms of abstract representation.
The periodic table of elements is commonly used in chemistry to look up chemical elements since it is structured in such a way that it demonstrates periodic patterns in the chemical properties of the elements. The Periodic table normally just reveals the element’s mark, not its full name.
The majority of the symbols are identical to the element’s name, although certain symbols have Latin origins. Gold, for example, is denoted by Ag from its Latin term “Argentum.” Another source is the symbol ‘Fe,’ which represents Iron and is derived from the Latin term “Ferrum,” which means “iron.”
A compound’s chemical composition is a symbolic reflection of its chemical makeup. Chemical formulae show the components that make up a compound’s molecules, as well as the quantities in which certain elements’ atoms interact to form such molecules. The chemical formula H2O, for example, means that two hydrogen atoms unite with one oxygen atom to create one water molecule.
A chemical reaction happens as two or more compounds bind together (or sever bonds), producing or absorbing energy in the process (see our Chemical Reactions module). A chemical equation is a shorthand description of a chemical reaction used by scientists.
Take, for example, the reaction of hydrogen with oxygen to create water. If we had a bottle of hydrogen gas and burned it in the presence of oxygen, the two gases would react and release energy, resulting in the formation of water. To write the chemical equation for this reaction, we will position the reactants (substances reacting) on the left side of the equation and an arrow pointing to the products (substances formed) on the right side of the equation (the products). Given this detail, one might deduce that the reaction’s equation is as follows:
“Mass in an isolated structure cannot be produced or lost, but it can be converted from one type to another,” according to the rule of conservation of mass.
For a low-energy thermodynamic operation, the mass of the reactants must be equal to the mass of the products, according to the law of conservation of mass. We may relate the law to the balancing of simple equations.
The addition of stoichiometric coefficients to the reactants and products is needed to balance chemical equations. This is important since a chemical equation must adopt the laws of conservation of mass and constant proportions, which implies that the reactant and component sides of the equation must contain the same number of atoms of each part.
A chemical equation has drawbacks of its own. They don’t offer you any details about:
In this chapter, we learned about the basics of the language of chemistry. With the information gathered, we can understand the chemical compounds and equations.
