The proper mixture of propane vapor, air, and ______ is needed for propane to burn.

Explanation:
Propane burning needs three things: fuel, an oxidizer, and heat. The fuel is propane vapor, and the air provides the oxygen, which is the oxidizer. But you still need a spark or flame — heat from an ignition source — to start the combustion. Without that heat, the propane-air mix won’t ignite, even if the proportions are right. Moisture would tend to cool the mixture and make ignition harder, and nitrogen in the air is inert and doesn’t enable burning. So the missing element that completes the burning mix is an ignition source.
