Based on experimental observations, identify compound E, cation(s) and anion(s) of compound F, and functional group(s) of G.

To answer the questions, the observations from the experiments are required. Since the observation and inference tables are empty in the provided image, it is not possible to determine the identity of compound E, the cation(s) and anion(s) of compound F, or the functional group(s) present in G.

Please provide the observations from the experiments for a complete solution.
