Propane burns in oxygen to produce carbon dioxide and water. What are the chemical formulas of the reactants and products?

The formulas of the reactants are C3H8, O, and CO2. The formula of the product is H2O.

The formulas of the reactants are C3H8 and O2. The formulas of the products are CO and H2O.

The formulas of the reactants are C3H8 and O2. The formulas of the products are CO2 and H2O.

What is the chemical equation for the burning of propane if all the products and reactants are in the gas phase?

4H2O(g) + 3CO2(g) + 5O2(g) → C3H8(g)

C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)

C3H8(g) + O10(g) → 3CO2(g) + 4H2O(l)

4H2O(l) + 3CO2(g) → C3H8(g) + 5O2(g)
