In word equation, you write chemical reaction using "words" and not "formuals". For eg, in word equation you would say something like Sodium Chloride and avoid saying NaCl (which is chemical formula)
1. Therefore word equation is : Propane + oxygen gas -------> carbon dioxide + water or Propane combines with oxygen gas to produce carbon dioxide and water is fine as well.
2. Reactants are usually on the left side so : Propane and Oxygen Gas.
3. Products are usually on the right side: Carbon dioxide and water
