![**Problem Statement:**
Given the standard heats of formation shown in Appendix B in your textbook, what is the \( \Delta H^\circ \) in kilojoules for the reaction:
\[ 3 \text{N}_2\text{O}_4 \text{(g)} + 2 \text{H}_2\text{O} \text{(l)} \rightarrow 4 \text{HNO}_3 \text{(aq)} + 2 \text{NO} \text{(g)} \]
Express your answer to one decimal place and include the appropriate units.
**Calculation Section:**
\[ \Delta H_\text{rxn}^\circ = \]
\( \boxed{\text{Value}} \quad \boxed{\text{Units}} \)
**Action Buttons:**
- A button with four small squares linked by lines, representing matrix or layout view.
- A button with the image of a Greek letter (possibly a subscript or superscript feature).
- Two arrow buttons for undo and redo actions.
- A button with a circular arrow, possibly for refreshing or resetting the form.
- A button with a keyboard icon, likely for switching to keyboard input mode.
- A question mark button for help or additional information.
**Submission Section:**
- "Submit" button: Click this to submit your answer.
- "Request Answer" link: Click this to request the answer if you need additional help.
Use the information and tools provided wisely to calculate the enthalpy change for the given reaction. Make sure to refer to Appendix B in your textbook for the standard heats of formation values needed for this calculation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdb8a321a-76ce-4a36-be9a-9e036c68cc95%2Fc6df0b6b-0a00-444c-b755-5479ffc6129c%2Fk41qj1e_processed.jpeg&w=3840&q=75)
