Final answer:
The empirical formula for decaborane is B5H7.
Step-by-step explanation:
The empirical formula for decaborane, B10H14, can be determined by finding the simplest whole number ratio of the atoms present in the compound.
To find the empirical formula, divide the subscripts of each element by their greatest common divisor. In this case, the greatest common divisor of 10 and 14 is 2. Dividing both subscripts by 2 gives the empirical formula B5H7.
Therefore, the empirical formula for decaborane is B5H7.
