Question
Complete the following chemical equations:
\[\ce{Z + 3 LiAlH4 -> X + 3LiF + 3AlF_3}\]
\[\ce{X + 6H2 -> Y + 6H2}\]
\[\ce{3X + 3O2 ->[Δ] B2O3 + 3H2O}\]
Solution
\[\ce{\underset{(Z)}{4BF3} + 3LiAlH4 -> \underset{(X)}{2B2H6} + 3LiF + 3AlF3}\]
\[\ce{\underset{(X)}{B2H6} + 6H2O -> \underset{(Y)}{2H3BO3} + 6H2}\]
\[\ce{\underset{(X)}{B2H6} + 3O2 ->[Δ] B2O3 + 3H2O}\]
