# A student mixes \(50.0 \text{ mL}\) of \(0.10 \text{ M HCl(aq)}\) with \(50.0 \text{ mL}\) of \(0.10 \text{ M NaOH(aq)}\) in a coffee-cup calorimeter and measures a temperature increase. Which of the following is the correct net ionic equation for the reaction that occurs?

A student mixes \(50.0 \text{ mL}\) of \(0.10 \text{ M HCl(aq)}\) with \(50.0 \text{ mL}\) of \(0.10 \text{ M NaOH(aq)}\) in a coffee-cup calorimeter and measures a temperature increase. Which of the following is the correct net ionic equation for the reaction that occurs?

- **A.** \(\text{H}^+\text{(aq)} + \text{OH}^-\text{(aq)} \rightarrow \text{H}_2\text{O(l)}\)
- **B.** \(\text{HCl(aq)} + \text{NaOH(aq)} \rightarrow \text{NaCl(aq)} + \text{H}_2\text{O(l)}\)
- **C.** \(\text{H}^+\text{(aq)} + \text{Cl}^-\text{(aq)} + \text{Na}^+\text{(aq)} + \text{OH}^-\text{(aq)} \rightarrow \text{Na}^+\text{(aq)} + \text{Cl}^-\text{(aq)} + \text{H}_2\text{O(l)}\)
- **D.** \(\text{Na}^+\text{(aq)} + \text{Cl}^-\text{(aq)} \rightarrow \text{NaCl(s)}\)
