Chapter 5 – Language of Chemistry

The following Topics and Sub-Topics are covered in this chapter and are available on MSVgo:

Introduction

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 ability of an element to blend is known as valency. In other terms, an atom’s valency is determined by the number of electrons it may acquire, share, or destroyed during a chemical reaction. The valency of elements is used to classify them as monovalent, divalent, and so on. Molecules are produced to fulfill an atom’s valency.

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.

  • Chemical formulae contain details regarding a compound’s chemical makeup. 
  • They also demonstrate how the constituent elements interact to form the compound. 
  • When describing a compound in a chemical equation, the chemical formula is important. 
  • Ions, free radicals, and other chemical organisms may also be described using chemical formulae.

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:
2H2+O2→2H2O

“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: 

  • Reactants and substances’ physical conditions As a consequence, the symbols “s” for solid, “l” for liquid, “g” for gas, and “vap” for vapour are applied to the equation. 
  • Temperature, strain, and catalyst also have an effect on the reaction. 
  • Reactant and substance amounts, dilute ‘dil.’ or condensed ‘conc.,’ are added in certain instances. 
  • The chemical reaction’s essence, such as if it’s reversible or permanent. 
  • The reaction’s speed 
  • The sum of heat that is given out or consumed as a consequence of the reaction. 
  • The time it takes for the reaction to end as some equations do not entirely reveal whether the reaction is complete.

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.

  1. What is a chemistry language?
    The words 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. 
  2. What’s the meaning of chemistry?
    Chemistry is the analysis of the properties, composition, and structure of substances (defined as elements and compounds), as well as the transformations and energy produced or absorbed during these processes. 
  3. What are the basics of chemistry?
    Chemical Nomenclature, Atomic Structure, Periodic Table, Lewis Structure, Chemical Reactions, Stoichiometry, Acid-Base Chemistry.
  4. Why doesn’t the mass change during chemical reactions?
    Atoms are neither formed nor destroyed during a chemical reaction. To shape compounds, the atoms of the reactants are simply rearranged. As a consequence, in a chemical reaction, there is no difference in mass.
  5. What is the concept of an ionic equation?
    Ionic equations are chemical equations in which electrolytes are described as dissociated ions.
