What happen when you use water and magnesium?
When it reacts, it will burn hot enough to decrease the water molecule, which turns to a Hydrogen
Gas. The Chicago Fire Department performed tests that showed that if you use large quantities of
water quickly, it could be used to cool the magnesium and later be extinguished.
Why magnesium used as flame thrower?
magnesium burns hot enough to separate water molecules and because hydrogen is flammable and
oxygen is what fire needs to get bigger your hose becomes a nice flame thrower :) Magnesium burns
so hot that when Water is added the water is instantly converted to hydrogen and oxygen (both
flammable gases).
What should to use to extinguish magnesium fire?
Any extinguishing agent composed largely of water normally may be expected to increase the rate of
burning. Thus soda-acid extinguishers and mechanical or chemical foam should not be used on a
magnesium fire. Likewise, inert gases such as carbon dioxide and nitrogen are ineffective on
magnesium fires.
What happens to hydrogen in a magnesium fire?
hydrogen burns very well in the presence of oxygen. It forms more water, which then rains down on
the magnesium fire, and makes more magnesium oxide and hydrogen.
why magnesium used in aircraft?
1.Magnesium alloys are also highly machinable
2. 50 percent lighter than aluminium
3. Reduces fuel cost.
4. Reduces carbon emission.
