Chemistry question (Stoichiometry)
1. The problem statement, all variables and given/known data
During the Apollo missions, each lunar module decelerated toward the surface of the moon by the oxidation of "Aerozine-50" fuel. Aerozine-50 is a blend of hydrazine, N2H4, and dimethylhydrazine, CH3()2N2H2, 50% by mass in each component (known to infinite precision). Nitrogen tetroxide, N2O4, was used as the oxidizing agent.
c. Determine the depth in centimeters of the equivalent water ice layer (density = 0.92 g/cm3) deposited on the surface if spread evenly over a circle 1.8 km in diameter.
2. Relevant equations
Assume that 2701 kg of Aerozine-50 was used in each deceleration, and that each component underwent ideal combustion according to the following unbalanced reactions:
3. The attempt at a solution
All I'm asking is if the ice layer is going to be cylinder or a sphere? I know how to do the problem i'm just not sure which they'd like.
