A word equation describes a chemical reaction using the names of chemicals only. For instance, the word equation for respiration is:
glucose + oxygen => carbon dioxide + water
A formula equation is a visual representation of a reaction using chemical formulas. A chemical formula is an expression that states the number and types of atoms that make up any given molecule using the symbols for the elements and sub-scripted numbers.
Chemical equation uses chemical formulae instead of names and is balanced. An example of this would be methane burning in oxygen:
CH₄ + 2O₂ →CO₂+ 2H₂O
