Answer:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Step-by-step explanation:
One molecule of propane gas reacts with five molecules of oxygen gas to form three molecules of carbon dioxide gas and four molecules of water vapor.
To every chemical equation, there are products and reactants:
Reactants → Products
Here:
Reactants:
1 mole of propane = C₃H₈
5 mole of oxygen gas = 5O₂
Products;
3 mole of CO₂ = 3CO₂
4 moles of water vapor = 4H₂O
The reaction equation is therefore;
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
