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.
The following reaction is to be used in a carbon sequestration process: CaSiO3 + CO2 → CaCO3 + SiO2 The reaction requires 37 kJ/mole CO2 to heat the reactants up to the correct temperature, and then releases 87 kJ/mole CO2. The atomic weights of Si and Ca are 28 and 40, respectively. Calculate the net energy released per ton of CaSiO3 reacted in this process.
The reaction between ammonia and oxygen is given below:
4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H,0(g)
We therefore know that which of the following reactions can also occur?
2 NH3(g) + 2 02(g) → N20(g) + 3 H20(1)
4 NO(g) + 6 H2O(g) → 4 NH3(g) + 5 O2(g)
N,0(g) + 3 H,0(1) → 2 NH3(g) + 2 02(g)
O None of the Above
