Diborane is a potential rocket fuel that undergoes combustion according to the reaction,
`B_(2)H_(6)(g) +3O_(2)(g) rarr B_(2)O_(3)(g) +3H_(2)O(g)`
From the following data, calculate the enthalpy change for the combustion of diborane:

Explanation

To calculate the enthalpy change for the combustion of diborane (B₂H₆), we can use Hess's law, which states that the total enthalpy change for a reaction is the sum of the enthalpy changes for the individual steps of the reaction.

### Step-by-Step Solution:

1. **Write the combustion reaction**:
\[ \text{B}_2\text{H}_6(g) + 3\text{O}_2(g) \rightarrow \text{B}_2\text{O}_3(g) + 3\text{H}_2\text{O}(g) \]
