Nothing, but if they are allow to burn water vapours are formed with explosion.
The hydrogen gas (H2) formed would escape and not be detected.
Hydrogen gas is H2. Oxygen gas is O2.
There is no noble gas configuration for hydrogen.
Universally hydrogen is by far the most abundant gas, accounting for about 88% of the atoms in the universe. The second most abundant gas is helium, as both of these elements are formed in stars. On earth hydrogen gas is actually fairly rare. This is simply that due to its extremely low mass it can easily escape the atmosphere, and as there aren't very many natural sources of hydrogen gas what is lost is not replaced. Note that this only applies to hydrogen gas: the element hydrogen is the tenth most abundant on earth.
Jupiter has more hydrogen and helium gas because it has more gravitational pull than any other planet so it pulls almost every gas with a greater efficiency and does not allow to escape from its atmosphere,as in the case of earth gases like (hydrogen) tends to escape easily.
Usually the burning of natural gas in a fixture for safety and to allow light to escape.
Water is split into hydrogen and oxygen gas in a process called electrolysis in which an electric current is passed through water. Pure water conducts electricity very poorly, so adding electrolytes allows a small current to flow through the water easily. Hydrogen and oxygen gas then bubble up from the electrodes in the water.
The escape of hydrogen gas
Because hydrogen gas is less dense than air(mostly nitrogen and oxygen), and the less dense gas flows to go above the more dense(and escape the atmosphere).

Strong smell
hydrogen and hydrogen gas are same hydrogen is gas
biotonic gas
Not yet, but future technologies might allow hydrogen -only engines.
The reaction produces hydrogen gas as will most reaction between an acid and a metal.
No. The flue must be open to allow the carbon monoxide to escape from the house.
