5. In general, how are word equations written to describe chemical reactions?
Len [333]

Answer is: Reactants and products are written in words; reactants are on the left, products are on the right side of reaction.

For example, balanced chemical reaction for cellular respiration (convert biochemical energy):  

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O or:

glucose + oxygen → carbon dioxide + water.

Glucose and oxygen are reactants and carbon dioxide and water are products of reaction.

This reaction is exothermic (energy is released).

Word equation is a chemical reaction expressed in words rather than chemical formulas.
