Question

Give reasons for the following:

A chemical equation is a short and simple way to represent a chemical reaction.

Answer 1

Chemical equations:

• These are symbolic representations of chemical reactions in which the reactants and the products are expressed in terms of their respective chemical formulae.
• Chemical reactions can be represented on paper with the help of chemical equations.
• Thus chemical equation is a short and simple way to represent a chemical reaction.
• For example; $\underset{\mathrm{Hydrogen}}{2{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Water}}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$
