The German Zeppelin Hindenburg was filled with hydrogen gas. Not surprisingly, the airship was destroyed in a violent fire near Lakehurst, New Jersey on May 6, 1937.
· The Hindenburg was originally supposed to have a different name. What was it?
· Write the balanced chemical equation for the combustion of hydrogen.
· What do these words mean in terms of chemical reactions? What are observable chemical indicators of each? Is the combustion of hydrogen exothermic or endothermic?

The Hindenburg’s original name was supposed to be the LZ 129. The name Hindenburg was quietly named by Eckener a year earlier.
2H₂₍g₎ + O₂ ₍g₎→2H₂O₍L₎ is the balanced equation for the combustion of hydrogen.
Exothermic is the giving off of energy; endothermic means the absorption of energy. When a chemical reaction is exothermic it is giving off energy, when it is endothermic it is absorbing energy. While practicing thermochemistry if the difference between a final temperature is negative than the chemical reaction is exothermic; if it is positive it is endothermic. More visible indicators would be the oxidation of metals or the setting of concrete. The combustion of hydrogen is exothermic because heat is given off.
