One example of rocket fuel is the reaction of hydrazine with dinitrogen tetroxide.
2N2H4(1) + N204(9)
3N2(g) + 4H2O(g) + heat
This reaction is hypergolic, meaning it does not need an external ignition
source, and highly exothermic. 1.000 liter of hydrazine is reacted with
excess dinitrogen tetroxide. The density of hydrazine is 1.021 g/mL, and
the molar mass is 32.0452 g/mol.
How many moles of water could be produced?

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
