Water is said to be produced when natural gas is burned. Is there some tangible way to measure the amount of this water? or some experiment to capture some, or even just a drop of this moisture produced?
In: Chemistry
all fire makes water. plants use sunlight, water and CO^2 to make burnable stuff and O^2 . Fire is just the opposite, releasing the sunlight, water, and CO^2 from fuel and O^2. you can expirimentally burn it in a sealed room, or you can just do the chemistry math. CH^4 + 2O^2 -> 2H^2 O +CO^2
Sure. Measure out a specific amount of the gas, trap it, burn it in the trap, and measure the water that settles to the bottom after you let the results cool down.
You could even have a condensing column where the hot gas rises through a chimney, cools, and the water droplets that form fall down into a bucket.
Two hydrogen atoms burned become one water molecule, and natural gas is mostly CH4, or 4 hydrogen atoms and a carbon. So every molecule of natural gas burns to make two water molecules and one carbon dioxide molecule.
We know how many molecules are in a given mass of natural gas, so you can calculate how many molecules of water it’ll make, and how many gallons that’d make too.
Capturing some is super easy. Find a metal cup and fill it with ice or cold water. Hold it over the burner of a natural gas stove, a few feet above the flame. Water vapor from combustion will condense on the outside of the cup.
Water is produced when any hydrocarbon burns.
See all the white behind the Saturn V rocket? That’s water vapor, not smoke. Kerosene, which fueled the Saturn V, makes water, CO2 and lot of energy when it burns, just like gasoline, propane, methane, etc.

You say this like it’s some mythical phenomenon, not first year chemistry lol
Anyway, you can catch some water vapor if you hold an upside down bowl above (not too close or it will get too hot!) a gas stove. The vapor will rise up, cool down and condense on the bowl.
