**Calculate \(\Delta H\) for the reaction:**

\[ 2\text{NH}_3(g) + \frac{1}{2}\text{O}_2(g) \rightarrow \text{N}_2\text{H}_4(l) + \text{H}_2\text{O}(l) \]

**given the following data:**

\[ 2\text{NH}_3(g) + 3\text{N}_2\text{O}(g) \rightarrow 4\text{N}_2(g) + 3\text{H}_2\text{O}(l) \quad \Delta H = -1010. \text{kJ} \]

\[ \text{N}_2\text{O}(g) + 3\text{H}_2(g) \rightarrow \text{N}_2\text{H}_4(l) + \text{H}_2\text{O}(l) \quad \Delta H = -317 \text{kJ} \]

\[ \text{N}_2\text{H}_4(l) + \text{O}_2(g) \rightarrow \text{N}_2(g) + 2\text{H}_2\text{O}(l) \quad \Delta H = -623 \text{kJ} \]

\[ \text{H}_2(g) + \frac{1}{2}\text{O}_2(g) \rightarrow \text{H}_2\text{O}(l) \quad \Delta H = -286 \text{kJ} \]

**\(\Delta H =\) \_\_\_\_ \text{kJ}**
