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 6.610E+5g of decaborane and 4.752E+5g of oxygen,
What mass of the other reactant is left over after the limiting reagent in the above mixture has been completely consumed?
If the total mass of both components in a decaborane/oxygen rocket must be 5.319E+5g, what mass of liquid oxygen should be used?
