Question

A chemical reaction can be represented using the ________ and ________ of the reactants and products.

• A. symbols
• B. formulae

Answer 1

Using symbols and formulae:

• The equation of a chemical reaction can be represented using the symbols and formulae of the reactants and products.
• For example:
• $\underset{\mathrm{Carbon}}{\mathrm{C}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Dioxide}}{\underset{\mathrm{Carbon}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}}$
• Therefore, a chemical reaction can be represented using the symbols and formulae of the reactants and products.
