1. How can you explain why ethanol is flammable while water is not or why table sugar turns black in the presence of heat while table salt do not? 2. You are given a task to separate the components of a black ballpen's ink. How will you do it? Describe the basic steps you probably will do in order to separate it. 3. Why Group 1 elements (i.e., Li, Na, K, Rb) tend to easily loose its valence electron making it cationic while Group 7 elements (F, Cl, Br, I) tend to easily gain electrons making it anionic? Explain your answer.
