Oxygen is colourless, support burning but don't smell.
Correct.
Oh Yeah, oxygen does indeed support burning! :)
Yes
The gas will explode in presence of oxygen! (and your match blown out, and hopefully you're not!)D.T.T.A.H.Only if brought in contact with H2 gas WITHOUT ANY O2 it would distiguish through absence of oxygen, but in practice this is IMPOSSIBLE to do (oxygen being present all the time as long as your match is burning, how else would it burn? see?)
cars burning gas and anything using gas
No. It is a compound made of the elements oxygen and hydrogen: H2O.
By burning the fossil fuels. Fossil fuels are natural fuels such as coal or gas, formed in the geological past from the remains of living organisms.
it goes out A glowing splint needs oxygen to basically keep glowing. It is a small fire in a way. When the glowing splint is added into an environment full of carbon dioxide, the splint goes out. Carbon dioxide in this case smothers the flame restricting the use of oxygen in combustion thus putting the flame out.
