because a lot of hydrogen is exploding at once :)
It makes a high pitched 'yelp.'
Hydrogen is the lightess, but most common element in the galaxy. It can be used to make balloons rise, be burned to give off heat, or burned to give engine thrust.

take a lighted splint (match) and place beside the test tube. If a squeaky pop sound is made then it is hydrogen
Henry Cavendish, a young English chemist, discovered that hydrogen is a separate substance in 1766. It was also discovered that hydrogen is found naturally in the atmosphere, and when hydrogen is burned it produces water vapor
It depends on the circumstances. Hydrogen will burn in air, to be sure. It will make a pop sound producing a blue flame and forming water when ignited in a test tube. But in the case of the Hindenburg, it just burned with extreme rapidity. Hydrogen mixed with air or oxygen is explosive, but will not explode in "bulk" form.
Car will make when running even if heater core is not burned out.
Water (H2O) is formed when hydrogen is burned by oxygen
Hydrogen is the lightess, but most common element in the galaxy. It can be used to make balloons rise, be burned to give off heat, or burned to give engine thrust.
pop sound when it contact with fire
Hydrogen combines with oxygen when burned, forming H2O (water).
When Hydrogen is burned in air it combines with Oxygen to form water. 2H2 + O2 -> 2H2O
the hydrogen burned in the air to form water.
water
When hydrogen is burned the product is pure water vapor. Here is the equation: 2H2 + O2 = 2H2O.
Hydrogen basically means "water maker" in Greek, because it forms water when burned."Hydro" means water, "gen" means generate. When hydrogen is burned, it produces water (vapor).
"Lambent" blue
