Exothermic
The reaction aluminum underwent during the disaster of Hindenburg was exothermic. It is exothermic because during this disaster it gave off heat.
Oxidation
i am pretty sure that it is endothermic because heat it not produced... but I'm not a 100 percent sure so don't quote me on that! k thanx bye! --------------------------------------------------------------------------------------------------------NEW USER You are obviously not very sure upon what endothermic and exothermic means. Obviously, heat was produced in LARGE QUANTITIES in the Hindenburg since COMBUSTION produces heat. So, of course it is exothermic.
When aluminum burns, the reaction is highly exothermic.
Yes it is. When these two chemicals react, the container they are in becomes heated. Exothermic refers to a release of heat and energy.
indothermic
4Al + 3O2 -> 2Al2O3
4Al+3O2-->2Al2O3
no!!!!!the Hindenburg did not explode. its aluminum painted skin caught fire from an electrostatic discharge. that fire ignited ordinary chemical hydrogen/oxygen fires as the lift gas bladders breached.no nuclear fusion was involved. not even a chemical explosion occurred.
The Hindenburg was originally intended to be filled with helium, but a United States military embargo on helium forced the Germans to modify the design of the ship to use highly flammable hydrogen as the lift gas. (At the time the USA was the only country that could produce helium in the amounts required.) The Germans had considerable experience with using hydrogen and implemented necessary safety measures to preempt an accident. Prior to the Hindenburg disaster, their safety record was impressive.
it gives us a new substance that is aluminum bromide therefore it is a chemical change.
