Hydrazine, N2H4, can be used as fuel to orient and maneuver spacecraft. The energy used to do so is obtained by reacting the hydrazine with dinitrogen tetroxide to form nitrogen gas and water vapor. Write and balance the chemical equation for this reaction. The spy satellite US-193 had 453 kg of hydrazine on board when it was destroyed. What mass of dinitrogen tetroxide would have had to be on board in order to completely react with the hydrazine? This reaction is a redox reaction. Assign oxidation states to each atom in the reaction, identify what is oxidized, what is reduced, the oxidizing agent, and the reducing agent. Answer in full please.
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
