- Are these systems moderated, explain. A. An aqueous solution of plutonium nitrate B. A tray of uranium trioxide (UO3) powder, containing 1% moisture.The compound diborane (B2H6) was at one time considered for use as a rocket fuel. Its combustion reaction is B2H6(g) + 3 O2(l) → 2 HBO2(g) + 2 H2O(l). The fact that HBO2, a reactive compound, was produced rather than the relatively inert B2O3 was a factor in the discontinuation of the investigation of the diborane as a fuel. What mass of liquid oxygen (LOX) would be needed to burn 234.4 g of B2H6? Answer in units of g. (part 2 of 2) What mass of HBO2 is produced from the combustion of 94.7 g of B2H6?
