Explanation:

Step1: Analyze NaCl decomposition

Electrolysis of solid NaCl breaks into its elements:
$$\text{NaCl}(s) \xrightarrow{\text{elect.}} \text{Na} + \text{Cl}_2$$

Step2: Analyze NH₃ decomposition

Heated ammonia decomposes into nitrogen and hydrogen:
$$\text{NH}_3 \xrightarrow{\Delta} \text{N}_2 + \text{H}_2$$
