Propane reacts with oxygen to produce carbon dioxide and water according to the following equation. Which ratio of components is correct?

C3H8 + 5O2 --> 3CO2 + 4H2O

For each mole of propane that reacts, 5 moles of oxygen are produced.
For each mole of oxygen that reacts, 3 moles of carbon dioxide are produced.
For every 3 moles of carbon dioxide produced, 5 moles of oxygen react.
For every 4 moles of water produced, 3 moles of propane react.

The correct ratio of components is: For every 1 mole of propane that reacts, 5 moles of oxygen are required, and 3 moles of carbon dioxide and 4 moles of water are produced.
