Answer:
a) read the word equation: “Propane has plus oxygen gas produces carbon dioxide gas plus water and heat”
b) convert the word equation to a chemical equation and complete the reaction. Be sure to balance the chemical equation.
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O + heat
Step-by-step explanation:
The combustion reaction is an exothermic chemical reaction of a substance or mixture of substances (called fuels) with oxygen (oxidizer). Characteristic of this reaction is the formation of a flame (incandescent gaseous mass that emits light and heat) that is in contact with the combustible substance.
The reaction of the fuel with oxygen produces gaseous substances, the most common being CO₂ and H₂O, and are generically called products, smoke or combustion gases. You must know that the fuel only reacts with oxygen and not with nitrogen, the other component of the air. Therefore the nitrogen in the air will pass entirely to the unreacted combustion products.
In this way, the reaction of propane (C₃H₈) and oxygen must give as products carbon dioxide, water and heat, and the balanced chemical equation will be :
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O + heat
