What is the equation for the formation reaction for hydrazine N2H4?
Problem: Hydrazine, N2H4, is a liquid used as a rocket fuel. It reacts with oxygen to yield nitrogen gas and water. N2H4 (l) + O2 (g) → N2 (g) + 2 H2O (l)The reaction of 6.50 g N2H4 evolves 126.2 kJ of heat.
How is the combustion of hydrazine N2H4 ):?
Hydrazine, N2H4(l)is used as a rocket fuel. The thermochemical equation for the combustion of hydrazine is: N2H4+ O2→ N2+ 2 H2O ∆H = -622.4 kJ.
Why is hydrazine used as a rocket fuel?
Hydrazine (N2H4) is used as a rocket fuel because it reacts very exothermically with oxygen to form nitrogen gas and water vapor. The heat released and the increase in number of moles of gas provide thrust.

Where is hydrazine found in?
Hydrazine can even be found in fossil fuels and nuclear power stations. As a powerful reducing agent, it acts as an oxygen scavenger, reducing metal oxides back into metals, and literally turning the chemical clock back on corrosion processes.
What is the chemical name of hydrazine?
Hydrazine, N2H4, is a chemical compound synthesized by Theodor Curtius in 1889. Also known as diazane, hydrozine has a density of 1.01g/mL, a melting point of 274K and a boiling point of 384K. Hydrazine is a chemical compound with the formula of N2H4.
What is the enthalpy of formation of hydrazine N2H4 L )?
The new enthalpy of formation of gas-phase hydrazine, based on balancing all available knowledge, was determined to be 111.57 ± 0.47 kJ/mol at 0 K (97.42 ± 0.47 kJ/mol at 298.15 K).
How much hydrazine is on an F 16?
In F-16, the EPU carries ~25l of hydrazine, which permits operation for about 10 minutes under normal load conditions and 15 minutes if the loads are less (i.e. in ground).
What type of fuel is used in rockets?
Today, liquid hydrogen is the signature fuel of the American space program and is used by other countries in the business of launching satellites. In addition to the Atlas, Boeing’s Delta III and Delta IV now have liquid-oxygen/liquid-hydrogen upper stages.
