Question

How can one make an equation more informative?

Answer 1

Hint: A chemical equation is a symbolic representation of a chemical reaction in the form of symbols and formulae, with the reactant entities on the left and the product entities on the right, with a plus sign between the entities in both the reactants and the products, and an arrow pointing towards the products, indicating the reaction's direction. The absolute values of the stoichiometric numbers are represented by the coefficients adjacent to the symbols and formulas of things.

Complete answer:
As illustrated below, it may be expressed as a word equation:
Carbon dioxide + Water + Methane + Oxygen
However, the chemical makeup of the reactants and products is not provided by this equation. As a result, a chemical equation is used to discover the properties of a chemical process. The chemical formulae of the reaction's chemicals are provided in the chemical equation.
The reactants (compounds or elements that undergo reactions) are displayed to the left of an arrow, while the products (compounds produced) are shown to the right of the arrow.
The reaction's direction is indicated by the arrow. As a result, the aforementioned
 $ C{{H}_{4}}+\text{ }{{O}_{2}}\to \text{ }C{{O}_{2}}+\text{ }{{H}_{2}}O $
However, this is an unfinished chemical equation. Because matter cannot be generated or destroyed, the rule of conservation of matter applies. Chemical reactions do not produce new atoms. A chemical reaction, on the other hand, reorganises them in diverse ways to produce a new molecule. As a result, the number of atoms in the reactants and products must be equal in a chemical equation. In the above equation, the number of hydrogen and oxygen atoms in the reactants and products are not equal. The following equation may be derived by balancing the number of atoms:
 $ C{{H}_{4}}+\text{ 2}{{O}_{2}}\to \text{ }C{{O}_{2}}+\text{ 2}{{H}_{2}}O $
To make a chemical equation more informative, I the physical states of the reactants and products (gaseous (g), liquids (l), aqueous (aq.), and solids (s)) are preserved.
In the equation, conditions like temperature, pressure, and catalyst are mentioned above/below the arrow.
 $ C{{H}_{4}}_{(g)}+\text{ 2}{{O}_{2(g)}}\to \text{ }C{{O}_{2(g)}}+\text{ 2}{{H}_{2}}{{O}_{(g)}} $ .

Note:
A chemical reaction is a process that results in the chemical change of one set of chemical substances into another set of chemical substances. Chemical reactions are often defined as changes in the locations of electrons in the formation and breaking of chemical bonds between atoms, with no change in the nuclei (no change in the elements present), and may be represented using a chemical equation.
