Decaborane, B10H14, was used as a fuel for rockets in the 1950's . It ignites spontaneously with O2 according to the following reaction:
B10H14 + 11O2 ? 5B2O3 + 7H2O
If a rocket's fuel tanks contain 9.847E+5g of decaborane and 9.938E+5g of oxygen, which of the reactants is the limiting reagent? (Enter the number corresponding to your choice: 1, 2, or 3.
1. Oxygen
2. Decaborane
3. Neither
What mass of the other reactant is left over after the limiting reagent in the above mixture has been completely consumed?
The best design for rockets is one in which both fuel materials run out at the same time to minimize excess mass. If the total mass of both components in a decaborane/oxygen rocket must be 3.011E+6g, what mass of liquid oxygen should be used?
