Question

When 0.2780.278 g of sodium metal is added to an excess of hydrochloric acid, 28902890 J of heat are produced. What is the enthalpy of the reaction as written?

 

2Na(s)+2HCl(aq)⟶2NaCl(aq)+H2(g)

 

**Thermochemistry Problem**

*Problem Statement:*

When 0.278 g of sodium metal is added to an excess of hydrochloric acid, 2890 J of heat are produced. What is the enthalpy of the reaction as written?

**Chemical Reaction:**

\[ 2 \text{Na(s)} + 2 \text{HCl(aq)} \longrightarrow 2 \text{NaCl(aq)} + \text{H}_2\text{(g)} \]

*Calculate the Enthalpy:*

- **Given:**
  - Mass of sodium = 0.278 g
  - Heat produced = 2890 J

*Box for Answer:*

\[ \text{Enthalpy of reaction:} \ \ \underline{\hspace{150px}} \ \ \text{kJ} \] 

In this exercise, students are expected to use stoichiometry and thermochemistry principles to calculate the reaction's enthalpy change.
