First you need to write a balanced equation. You are given that propane undergoes a combustion reaction that produces carbon dioxide and water.
Unbalanced: C3H8 + O2 ---> CO2 + H2O
Balanced: C3H8 + 5O2 ---> 3CO2 + 4H2O
Givens:
42.0 grams C3H8 (Molecular mass 44.0 g)
115.0 grams O2 (Molecular mass 32.0 g)
Molecular mass of CO2: 44.0 g
Mole ratio 1:5:3:4 (C3H8:O2:CO2:H2O)
Then you need to find which of the reactants are the limiting reactant (lowest value) and which is the excess reactant. The limiting reactant is what you will base the rest of the problem on. To do this, you convert each measurement to moles from grams.42.0 g C3H8 / (44.0 g) = .955 moles C3H8 115.0 g

Take the amount of propane and use stoichiometry to find the amount of water produced in grams.
42.0 g C3H8 / (44.0 g) × (4 moles) × (18 g) = 68.7 grams H2O
In the presence of excess oxygen, propane burns to form water and carbon dioxide. When not enough oxygen is present for complete combustion, incomplete combustion occurs when propane burns and forms water, carbon monoxide, and carbon dioxide.

When methane is burned in oxygen, assuming complete combustion, the products are carbon dioxide and water.

Burning propane is called combustion, in which propane combines with oxygen to form carbon dioxide and water.
When hydrocarbons are burned, carbon dioxide is formed. If the hydrocarbon is burned in low amount of oxygen, carbon monoxide can be formed. Carbon monoxide is harmful for animals.
Yes, indeed, as anyone with a propane-fueled heater can experience!
